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 :-)

In the poportion 1/z =4/5/8 which number is equal to z in the proportion

Nady [450]

Answer:

case 1) $z=10$

case 2) $z=5/32$

Step-by-step explanation:

case 1) we know that

Using proportion

$\frac{1}{z}=\frac{(4/5)}{8}$

solve for z

$\frac{1}{z}=\frac{(4/5)}{8}\\ \\z(4/5)=8\\ \\z=8*5/4\\ \\z=10$

case 2) we know that

Using proportion

$\frac{1}{z}=\frac{4}{5/8}$

solve for z

$\frac{1}{z}=\frac{4}{5/8}\\ \\4z=5/8\\ \\z=5/32$
