Answer:

x = -2

Step-by-step explanation:

The first step would be to distribute 3 to both the x and 5, which would result in $3x + 15 = 9$ .

The next step would be to subtract 15 from 9 to isolate the 3x, resulting in $3x = -6$ .

The last step would be to divide 3 by -6 to get the value of x.

$\frac{3x}{3} = \frac{-6}{3}$

$\frac{-6}{3} = -2$

$x = -2$

A soccer team uses 5-gallon coolers to hold water during games and practices. Each cooler holds 640 fluid ounces. The team has s

polet [3.4K]

<h3>Answer: 640c - 6.25s - 8.75g</h3>

===============================================

Work Shown:

s = number of small cups

g = number of large cups

c = number of coolers

----------

1 cooler = 640 fluid ounces

c coolers = 640c fluid ounces

1 small cup = 6.25 fluid ounces

s small cups = 6.25s fluid ounces

1 large cup = 8.75 fluid ounces

g large cups = 8.75g fluid ounces

----------

T = total amount of water poured

T = (amount from small cups) + (amount from large cups)

T = 6.25s+8.75g

L = amount of water left

L = (original total amount of water) - (amount of water poured out)

L = 640c - T

L = 640c - (6.25s+8.75g)

L = 640c - 6.25s - 8.75g
