HELP ASAP DUE TOMORROW!!!
On a family outing, Tyler bought 5 cups of hot cocoa (x)
and 4 pretzels (y) for $18.40. Some of his family members
would like a second serving, so he went back to the same
food stand and bought another 2 cups of hot cocoa (x) and
4 pretzels (y) for $11.20.
Answers:
x = 2.40
y = 1.60
This means 1 hot cocoa costs $2.40 and 1 pretzel costs $1.60
=======================================
Work Shown:
x = cost of 1 cup of hot cocoa
y = cost of 1 pretzel
5x = cost of 5 cocoas
4y = cost of 4 pretzels
5x+4y = cost of 5 cocoas+4 pretzels
5x+4y = 18.40
----------------
2x = cost of 2 cocoas
4y = cost of 4 pretzels
2x+4y = cost of 2 cocoas+4 pretzels
2x+4y = 11.20
----------------
The system of equations we have is
[tex]\begin{cases}5x+4y = 18.40\\2x+4y = 11.20\end{cases}[/tex]
Note how 4y shows up twice. This is handy to be able to get rid of the y terms completely.
How? By subtracting the equations straight down
The x terms subtract to 5x-2x = 3x
The y terms subtract to 4y-4y = 0y = 0 and they go away
The right hand sides subtract to 18.40 - 11.20 = 7.20
After those three separate subtractions, we have this new equation:
3x = 7.20
Divide both sides by 3 to isolate x
3x/3 = 7.20/3
x = 2.40
Each hot cocoa costs $2.40
Now use this x value to find y. You can pick any equation you want as long as it has x,y in it. I'll pick the first equation
5x+4y = 18.40
5(2.40)+4y = 18.40
12+4y = 18.40
4y = 18.40-12
4y = 6.40
y = 6.40/4
y = 1.60
Each pretzel costs $1.60
If we picked on the second equation, we should get the same y value
Let's find out
2x+4y = 11.20
2(2.40)+4y = 11.20
4.80+4y = 11.20
4y = 11.20-4.80
4y = 6.40
y = 6.40/4
y = 1.60
We get the same result as before.
To check the answers, you need to plug those values back into the two original equations and simplify. You should get the same thing on both sides.

Answer:
3
Step-by-step explanation:
lxl+6=3
|x|=3-6

the | | sign is the inequality sign which aignifies the +and - value
+x=-2 or -x=-2
hence x=2 or -2

A square-shaped canvas painting was enlarged by adding a 4-centimeter wide decorative frame to the length and width of the canvas. If the area
of the framed painting is 625 square centimeters, what is the side length of the bare canvas?
A
17 centimeters
B.
19 centimeters
C
21 centimeters
D
25 centimeters
Answer:
21cm
Step-by-step explanation:
Area if the canvas = L²
If the length is increased by 4
A = L²
625 = L²
L = √625
L = 25cm
If the 4cm is added to the length of the canvas, the original length will be 25-4 = 21cm. hence the length of the bare canvas is 21cm

HELP I NEED THE ANSWER FAST its says true or false false ( the absolute of a number can be negative
Answer:
False
Step-by-step explanation:
Answer: False
Step-by-step explanation: Absolute value is the number of whole numbers the number is away from zero. So it can only be positive because you cannot have a number negative spaces away from zero
Naomi works in a music shop and earns $42 per day. She earns an extra $2 for each CD she sells. If Naomi wants to earn at least $80 per day, which inequality shows the minimum number of CDs, n, that she should sell?
42 + 2n ≤ 80, so n ≤ 19
42 + 2n ≥ 80, so n ≥ 19
42 + 2n ≥ 80, so n ≥ 36
42 + 2n ≤ 80, so n ≤ 36
Answer:
B. 42 + 2n ≥ 80, so n ≥ 19
Step-by-step explanation:
42 + 2n ≥ 80
Subtract 42 from both sides
2n ≥ 38
Divide both sides by 2
n ≥ 19
Hope I helped :)
Please consider Brainliest :)
Answer:
42 + 2n ≥ 80, so n ≥ 19
Step-by-step explanation:
If she wants to make at least $80 the she would need to sell a number of cedis in addition to her $42
That is:
Let n be the number of CDs
42 + 2n
and to get at least $80, (at least meaning $80 dollars or more)
So that will be:
42 + 2n ≥ 80
So to get at least 80 dollars, she'll have to sell 19 CDs
Why 19 CDs? 42 + 2n which is 42 + 2(19) = 80
Which is why 42 + 2n ≥ 80, so n ≥ 19

Mai and Priya were on scooters. Mai traveled 15 meters in 6 seconds. Priya travels 22 meters in 10 seconds. Who was moving faster?
Answer:
Priya
Step-by-step explanation:
We can use division
Mai: 15/6 = 2.5 meters per second
Priya: 22/10 = 2.2 meters per second
Since Priya is going 2.2 meters per second, she is going faster.
REASONING An even integer can be represented by the expression $2n$ , where $n$ is any integer. Find three consecutive even integers that have a sum of 54. The three consecutive even integers, in order from least to greatest, are , , and . Explain your reasoning. Expressions for the next two consecutive even integers after $2n$ are and . Solving the equation $=54$ , and substituting the solution into the expressions for the three integers results in the three integers given above.
Answer:
First Integer = 16
Second Integer = 18
Third integer = 20
Step-by-step explanation:
An even integer is represented by 2n
Where n is any integer
Let :
First Integer = 2n - 2
Second Integer = 2n
Third integer = 2n + 2
The sum of three even consecutive numbers = 2n - 2 + 2n + 2n + 2
= 2n + 2n + 2n - 2 + 2 = 54
= 6n = 54
n = 54/6
n = 9
First Integer = 2n - 2 = 2(9) - 2
= 16
Second Integer = 2n = 2(9)
= 18
Third integer = 2n + 2 = 2(9) + 2
= 20
