Answer:
Step-by-step explanation:
Let the number of children = c
The number of adults = a
Total people = 528
c + a = 528 ------------------------(I)
Total price = $ 985
1.25c + 2.25a = 985 ---------(II)
Multiply equation (I) by (-1.25).
(I)*(-1.25) -1.25c - 1.25a = - 660
(II) 1.25c + 2.25a = 985 {add, c will be eliminated}
a = 325
Number of adults = 325
Plugin the value of a in equation (I)
c + 325 = 528
c = 528 - 325
c = 203
Number of children = 203

Answer:
7/23
Step-by-step explanation:
Multiples of 4 are 4 and 8
4 was spun 4 times
8 was spun 3 times
total spins = 2+3+2+4+5+3+1+3=23
P( 4 or 8) = number of times spun / total
= (4+3) / 23

Use the graph of g to solve.
Find g(-16)
Answer:
g(-16) = 6
Step-by-step explanation:
We want the value of the function when x = -16
The function is constant from x = -8 to the left. The value is 6
g(-16) = 6
Answer:
g(-16) = 6
Step-by-step explanation:
The upper horizontal line with an arrow to the left means that the value of function g remains at 6 from x = -8 as it approaches negative infinity. Since -16 is in the interval from -8 to -infinity, then
g(-16) = 6

A train goes at a constant speed. If it covers 150 miles in 2/1 2 hours,
e
How long would it take for that train to cover 270 miles?
Answer:
x =4.5 hours
Step-by-step explanation:
We can use ratios to solve
150 miles 270 miles
--------------- = --------------
2.5 hours x miles
150 *x = 270*2.5
Divide each side by 150
150x/150 = 270*2.5/150

Answer:
[tex]x=0.5[/tex]
[tex]y=anything[/tex]
Step-by-step explanation:
15−x+y=14−(−x−y)
15-x+y=14+x+y
Subtract 14 from both sides
1-x+y=x+y
Subtract y from both sides
1-x=x
Add x to both sides

cost for each chocolate gift basket?
A) $20 B) $25 C) $30 D) $54
PLS HELP ME ASAP!
Answer: The cost for each chocolate gift basket is b)$25.
Step-by-step explanation:
Hi, the correct equations are:
6x + 5y =300
3x + 7y = 285
So, if we multiply the second equation by 2, and subtract the first equation to the second equation:
6x +14 y= 570
-
6x +5y =300
_________
9y = 270
Solving for y:
y = 270/9
y = 30
Substituting y=30 on any equation:
6x + 5y =300
6x + 5(30) =300
Solving for x (cost for each chocolate gift basket)
6x+150 =300
6x =300-150
6x = 150
x =150/6
x = $25
A can contains 414 mL of chicken broth. Roland poured 4 cans of broth into a pot for a soup recipe. How many liters of broth did Roland pour into the soup?
Answer:
1.656 litres
Step-by-step explanation:
1 can = 414ml
4 cans = 414 x 4
4 cans = 1,656ml
1,656ml = 1.656 litres
The amount of broth poured into the soup is 1.656 L.
Given data:
To determine the number of liters of broth Roland poured into the soup, we need to convert the volume of the broth from milliliters (mL) to liters (L).
Given that each can contains 414 mL of chicken broth, and Roland poured 4 cans of broth into the pot, we can calculate the total volume in milliliters:
414 mL/can * 4 cans = 1656 mL
On simplifying the equation:
To convert milliliters to liters, we divide by 1000 since there are 1000 milliliters in a liter:
1656 mL / 1000 = 1.656 L
Hence, Roland poured 1.656 liters of broth.

Which equation in the form y = mx + cs models Emma's situation?
O y = 20x + 0.15
O y = 20x + 15
O y = 20x + 0.15s
y = 20x + 15s
Help!!!!
Answer:
the answer would be y = 20x + 0.15s
Step-by-step explanation:
In this problem you would just plug in your facts. 20 would plug in for m, 15% would change to 0.15 then you would plug 0.15 into c.
The equation represents Emma's situation is y = 20x + 0.15s. The correct option is C.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The equation in the form y = mx + cs models Emma’s situation is
y = 20x + 0.15s

What is the factorization of 729x^15 + 1000?
729x¹⁵ + 1000
This is a case of a sum of cubes.
729 is the cube of 9
1000 is the cube of 10
x¹⁵ is the cube of x⁵
A sum of perfect cubes can be factored into
(a + b) (a² - ab + b²)
(9x⁵+ 10) ((9x⁵)²-(9x⁵)(10) + 10²)
(9x⁵ + 10) (81x¹⁰ - 90x⁵ + 100) THIS IS THE FACTORIZATION
9x⁵ (81x¹⁰ - 90x⁵ + 100) + 10(81x¹⁰ - 90x⁵ + 100)
729x¹⁵ - 810x¹⁰ + 900x⁵ + 810x¹⁰ - 900x⁵ + 1000

subtract 2x from each side
4x-2x = 2x+6-2x
2x = 6

He uses place value and finds the sums of the hundreds, tens, and ones.
What is the sum of the tens? Enter your answer in the box.
Answer:
[tex]Sum = 100[/tex]
Step-by-step explanation:
Given
468 and 241
Required
Sum of the Tens
Breaking 468 to smaller bits; we have
Hundred = 400
Tens = 60
Units = 8
Breaking 241 to smaller bits; we have
Hundred = 200
Tens = 40
Units = 1
The question requests for the sum of the Tens;
The sum of the tens goes thus;
[tex]Sum = Tens_{468} + Tens_{241}[/tex]
[tex]Sum = 60 + 40[/tex]
[tex]Sum = 100[/tex]
Hence, the sum of tens of 468 and 241 is 100
