Answer:

x= -4

Step-by-step explanation:

First you have to do the parenthesis in the fraction so, it would be

4x+16/5=-4-x

I would then multiply both sides by 5 so,

4x+16=-20-5x

Add 5x to each side

9x+16=-20

Add 20 to both sides

9x+36=0

Subtract 36 to both sides

9x=-36

Divide by 9 to both sides

x= -4

Answer:

x=-4

Step-by-step explanation:

Let's solve your equation step-by-step.

4(x+4) /5  =−4−x

Step 1: Simplify both sides of the equation.

4(x+4) /5  =−4−x

Step 2 Distribute

4/5x+16/5=-x-4

Step 3 Add x to both sides

4/5+16/5+x=-x+4+x

Subtract 16/5 from both sides

9/5x=-36/5

Multiply by 5/9

x=-4

Can someone help with problems 22, 23 & 25
Sonja [21]

#22: 10.2 gallons for $2.59 each = 10.2 x 2.59, which rounded is $26.42.

#23: 12 pieces that are 6.45 in wide each = 12 x 6.45, which is 77.4 in.

#25: Aaron started with $38.

$22.47 + $8.53 + $6.50 is $37.50.

38.00 - 37.50 is .50 or 50 cents.


Hope that helps!
