Answer:
1. 24 qt
2. 200 people
Step-by-step explanation:
1. Use a proportion.
1.5 qt to 8 people = x qt to 128 people
1.5/8 = x/128
Cross multiply.
8x = 1.5 × 128
8x = 192
x = 24
Answer: 24 qt
2.

number of people at pool = 360
5/9 × 360 = 200
Answer: 200 people

A. 5-2
B. (7+x)^2
C. 5(y-2)
D. 4/x^2
Answer:
Step-by-step explanation:
Let x be the larger number.
Let y be the smaller number.
x - y = 5
x^2 - y^2 = 65 Factor the left.
(x - y)(x + y) = 65 Substitute the first equation into this equation.
5 *(x + y) = 65 Divide both sides by 5
x + y = 65/5
x + y = 13
Now list the two binomials one after the other.
x + y = 13
x - y = 5 Add
2x = 18 Divide by 2
2x/2 = 18/2
x = 9
x + y = 13 Substitute 9 for x
9 + y = 13 Subtract 9 from both sides.
y = 13 - 9
y = 4
Answer
- <em>x = 9</em>
- <em>y = 4 </em>
