The length of a rectangle is 5 cm longer than its width.
blondinia [14]

Equation To write :2 {x+ ( x+5) }=30

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

2(x+x+5)=30

Step 1: Simplify both sides of the equation.

2(x+x+5)=30

(2)(x)+(2)(x)+(2)(5)=30(Distribute)

2x+2x+10=30

(2x+2x)+(10)=30(Combine Like Terms)

4x+10=30

4x+10=30

Step 2: Subtract 10 from both sides.

4x+10−10=30−10

4x=20

Step 3: Divide both sides by 4.

4x

4

=

20

4

x=5

So... x+5=10.

Area =5x10=50 cm squared.

andreyandreev [35.5K]

Answer:

$600 in commission for the week paying 15% on up to $1000 daily

Step-by-step explanation:

To find the sales commission, multiply the percentage 15% as 0.15 against each sales up to $1000.

Monday - 0.15 (800) = $120

Tuesday - 0.15 (600) = $90

Wednesday - 0.15 (1000) = $150

Thursday - 0.15 (800) = $120

Friday - 0.15 (800) = $120

In total that's, $600 in commission.
