Answer:
132 tiles
Step-by-step explanation:
Each tile cost $4
The adhesive/grouting material costs $17.82.
If the contractor pays a total of $545.82
Let the number of tiles be represented as x
The equation is represented as:
$17.82 + $4 × x = $545.82
17.82 + 4x = 545.82
Collect like terms
4x = 545.82 - 17.82
4x = 528
Divide bother sides by 4
4x/4 = 528/4
x = 132
The number of ceramic tiles the contractor bought = 132 tiles

6. Given: angle 1 and angle 2 are supplementary
Prove: p Il a
Answer:
Look at the picture. M angle1= M angle 3 might be wrong
Angle 1 and angle 2 are supplementary, so p and a are parallel by transversal properties and angle congruence.
as it is already stated that Angle 1 and angle 2 are supplementary.
from the angle 2 and 3 are supplementary according to linear pair postulate
Supplementary angles add up to 180 degrees, so we have:
angle 1 + angle 2 = 180
Using the characteristics of parallel lines and transversals, we can determine that if angles 1 and p are complementary and angles 1 and 2 are congruent, then angles p and 2 are also complementary.
according to transitive property of equality
angle1 +angle 2= angle 3+ angle 4
consecutive interior angle theorem
angle 1 = angle 3
∠1≅∠3
lines converse angles converse.

Evaluate the expression m +(3n - 5)2 when m = 6 and n = 4.
m+ (3n - 5)2 = 6+ (3. 4 – 5)2
What’s the answer
Answer: 55
Step-by-step explanation:
M + (3n - 5)² = 6 + (3 x 4 – 5)^²
* 6 + (7)²
* 6 + 49 = 55
Sorry if the other answer misleads you. Here is the real answer!
The answer to the expression m +(3n - 5)² is 55.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
m +(3n - 5)²
Now, put the value of m= 6 and n= 4 we get
m +(3n - 5)²
= 6 +(3(4) - 5)²
= 6 +(12 - 5)²
= 6 +(7)²
= 6+ 49
= 55
Hence, the answer is 55.

Find the GCF of 12, 16, and 20
Answer:
4
Step-by-step explanation:
4 is the GCF od 12, 16 and 20
Answer:
4
Step-by-step explanation:
The greatest common factor is the largest number that is a shared factor of all 3 numbers (the greatest number they can all divide into). To find the GCF, we can list all the factors of the 3 numbers and then find the largest one that is common to all three sets.
Factors of 12 are: 1,2,3,4,6,12
Factors of 16 are: 1,2,4,8,16
Factors of 20 are: 1,2,4,5,10,20
We can see that 1,2 and 4 are the numbers common to all three sets but 4 is the largest so 4 is our greatest common factor.

Huang Yi works as a paleontologist and a sculptor. She earns \$5{,}500$5,500dollar sign, 5, comma, 500 per month as a paleontologist and \$4{,}500$4,500dollar sign, 4, comma, 500 per month as a sculptor. Huang Yi wants to make more than \$50{,}000$50,000dollar sign, 50, comma, 000 this year. In the inequality shown above, PPP represents the number of months Huang Yi can work as a paleontologist and SSS represents the number of months she can work as a sculptor to reach her goal. If Huang Yi worked for 666 months as a paleontologist this year, what is the minimum whole number of months that she must work as a sculptor to reach her goal?
Answer:
4 months
Step-by-step explanation:
Let P represents the number of months Huang Yi can work as a paleontologist and S represents the number of months she can work as a sculptor to reach her goal.
If she works for P months as an paleontologist, her income would be 5500P while if she works for S months as a sculptor her income would be 4500S.
Her total income = 5500P + 4500S
Since she wants to earn more than $50000, hence:
5500P + 4500S > 50000
Given she worked as a paleontologist for 6 months, therefore:
5500(6) + 4500S > 50000
33000 + 4500S > 50000
4500S > 50000 - 33000
4500S > 17000
S > 17000/4500
S > 3.78
S > 4
The minimum whole number of months that she must work as a sculptor to reach her goal is 4 months

A ticket to see your favorite baseball team cost $43.32. The price decreases by $0.25 for every game loss during the regular season. What equation could you use to find the cost C of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 24 games. What is the price of a ticket after the team loses 24 games?
Answer:
$37.82Step-by-step explanation:
Given that the cost of the ticket is
$43.32
and the price decrease is by $0.25
let the cost be C
and let the number of losses be L
the expression for the cost we be
C=43.32-0.25L
for the number of losses which is 22 we have
C=43.32-0.25(22)
C=43.32-5.5
C=37.82
Therefore the price after 22 losses is $37.82

amount charged for the egg breakfast.
(b) Graph the equations in the system
(c) Use your graph to estimate how much each item cost.
Answer:
Answer:
(a) The system of equations is:
2r + b = 8.40
3r + b = 9.35
(b) The graph is attached down
(c) By using the graph
The cost of the refill is $0.95
The cost of the egg breakfast is $6.5
Step-by-step explanation:
Let r is the amount charged for a refill and b for the amount charged for the egg breakfast
∵ r is the amount charged for a refill
∵ b is the amount charged for the egg breakfast
∵ You ordered 2 drink refills and the egg breakfast, for a total of $8.40
∴ 2r + b = 8.40 ⇒ (1)
∵ Your friend ordered 3 refills and the egg breakfast for $9.35
∴ 3r + b = 9.35 ⇒ (2)
(a) The system of equations is:
2r + b = 8.40
3r + b = 9.35
(b) The graph is attached down
From the graph
The red line represents equation (1)
The blue line represents equation (2)
The two lines intersected at point (0.95, 6.5)
(c) By using the graph
The cost of the refill is $0.95
The cost of the egg breakfast is $6.5

What expression is equivalent to: 100
Answer:
10 x 10, 2 x 50
Step-by-step explanation:
a water turck is filling a swiming pool. the euqation that represents this relationship is y = 19.75x where y is the number of gallons of water in the pool and x is the number of minutes the truck has been filling the pool choose true or false for each statement
Answer:
TrueStep-by-step explanation:
Given the expression
y = 19.75x
let us see the solution from this angle
we know that
speed=distance/time
distance=speed*time
i.e quantity=rate*time
y = 19.75x
y=the quantity =number of gallons
19.5= the rate of flow
therefore
x= the time in minutes
Two rival cleaning companies charge to dust houses. Captain Dustsalot charges
$20 per house call plus $ 12 per room, and Dedusters charges $30 per house call
plus $10 per room. Abigail wants to know how many rooms she must get dusted
so that Captain Dustsalot is more expensive than Dedusters. Which inequality
should she use to figure this out if x represents the number of rooms she gets
dusted?
Answer:
6 rooms
Step-by-step explanation:
20+12x=30+10x
12-10=2
20+2x=30
30-20=10
2x=10
10/2=5
5 rooms to make them equal so 6 rooms to make captain datalot more
The inequality is 20+12x> 30 +10x.
what is an inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
Captain Dustsalot charges
$20 per house call
$ 12 per room
Dedusters charges
30 per house call
$10 per room
let x represents the number of rooms she gets dusted.
so, inequality that represents rooms she must get dusted so that Captain Dustsalot is more expensive than Dedusters.

Please help! A line has a slope of -2 and a y-intercept of -3. Graph the line using the slope and y-intercept. Which of the following points lie on this same line? Check all that apply.
Answer:
2. -1.5, 0
3. -6, 9
5. 3, -9
Step-by-step explanation:
Given parameters:
Slope = -2
y - intercept = -3
Unknown:
The point that lies on the line = ?
Solution:
To do the equation of the line,
y = mx + c
y and x are the coordinates
m is the slope
c is the y -intercept
Input the parameters:
y= -2x -3
The points that lie on the line will conform with the equation:
y + 2x = -3
1. -2, 0
y = 0 and x = -2
0 + (-2)2 = -4
2. -1.5, 0
y = 0 and x = -1.5
0 + 2(-1.5) = -3
3. -6, 9
y = 9, x = -6
9 + 2(-6) = 9 - 12 = -3
4. 2, -3
y = -3 and x = 2
-3 + 2(2) = -3 + 4 = 1
5. 3, -9
y = -9, x = 3
-9 + 2(3) = -9 + 6 = -3
6. -4, 4
y = 4 , x - 4
4 + 2(-4) = 4 - 8 = -4
The boldened coordinates line on the same line.
