Answer:

x = 25

Step-by-step explanation:

2x-20=30

First, isolate the term with x in it by moving everything else to the other side:

2x = 30 + 20

Simplify like terms:

2x = 50

Further isolate the x by dividing by 2 on both sides:

2x/2 = 50/2

The 2 cancels out on the left, leaving:

x = 25

Answer:

x= 25

Step-by-step explanation:

Simplifying 2x + -20 = 30

Reorder the terms: -20 + 2x = 30

Solving -20 + 2x = 30

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '20' to each side of the equation. -20 + 20 + 2x = 30 + 20

Combine like terms: -20 + 20 = 0 0 + 2x = 30 + 20 2x = 30 + 20

Combine like terms: 30 + 20 = 50 2x = 50

Divide each side by '2'. x = 25

Simplifying x = 25

Mike works in a toy store. One week, he worked 38 hours and made $220. The next week, he received a raise, so when he worked 30
garik1379 [7]

Answer:

$0.21

Step-by-step explanation:

Let x be the amount of money earned per hour before raise and y be amount of money earned per hour after raise.

We have been given that before raise he worked 38 hours and earned $220. We can represent this information as: 38x=220

We are also told that the next week, he received a raise. After raise he worked 30 hours and made $180. We can represent this information as: 30y=180.

Let us solve for x and y.

x=\frac{220}{38}

x=5.7894736842105263

Therefore, before raise Mike earned $5.7894 per hour.

y=\frac{180}{30}

y=6

Therefore, after raise Mike earned $6 per hour.

Now let us subtract 5.7894 from 6 to find Mike's raise.

\text{Amount of raise}=6-5.7894

\text{Amount of raise}=0.2106\approx 0.21

Therefore, amount of Mike's raise to the nearest cent is $0.21.

10 = 10 to the nearest hundredth

10 = 10 to the nearest thousandth

= 0 to the nearest tenth

= 0 to the nearest hundredth

= 0 to the nearest thousandth
