Answer:

Step-by-step explanation:

The ratio of yellow paint to blue paint is 4:3. We can make the largest amount of green paint by using all of the 20 quarts of yellow paint so we have to solve for x in 4:3 = 20:x, since 4 * 5 = 20, 3 * 5 = x so we use 15 qts of blue paint, therefore we will have 20 + 15 = 35 qts of green paint.

13 + 11s = -15 + 8s − 20

koban [17]

Answer,

S = -16

Explanation,

Step 1: Simplify both sides of the equation.

13 + 11s = − 15 + 8s − 20

13 + 11s = − 15 + 8s + − 20

11s + 13 = (8s) + (− 15 + − 20) (Combine Like Terms)

11s + 13 = 8s + − 35

11s + 13 = 8s − 35

Step 2: Subtract 8s from both sides.

11s + 13 − 8s = 8s − 35 − 8s

3s + 13 = − 35

Step 3: Subtract 13 from both sides.

3s + 13 − 13 = − 35 − 13

3s = − 48

Step 4: Divide both sides by 3.

3s/3 = −48/3

s = -16

Hope this helps :-)

What is the slope of the line with an equation of 5x - 3y = -12

Hoochie [10]

Answer: $m=\frac{5}{3} =1.67$

Step-by-step explanation:

Original equation: $5x-3y=-12$
Subtract 5x from both sides of the equation: $-3y=-5x-12$
Divide both sides of the equation by -1: $3y=5x+12$
Divide both sides of the equation by 3 to get y on the left, leaving the equation in $y=mx+b$ form: $y=\frac{5}{3}x+4$
Evaluate. Slope is equal to m in this form, so the slope is $m=\frac{5}{3}$ .
