Answer:

x = 42

Step-by-step explanation:

1 - (2x + 9) = 4(21 - 2)

Distributive property ( multiply whatever is in the parenthesis by (-) for the first one, and (4) for the second one)

1 - * 2x + - * 9 = 4 * 21 - 4 * 2

1 - 2x - 9 = 84 - 8

Combine like terms

-8 - 2x = 76

Add 8 on both sides

-8 + 8 - 2x = 76 + 8

2x = 84

Divide by 2 on both sides to isolate the variable

2x/2 = 84/2

x = 42

Hope this helped!

Ellie runs 5/6 mile in 10 minutes.what is ellie's speed in miles per minute?
olganol [36]

Answer:

1/12 miles/minute

Step-by-step explanation:

To figure out how fast ellie runs in 1 minute, we can set up this equation:

5/6 = 10x (x being the speed per minute)

We can divide both sides by 10

5/60 = x

Then simplify the fraction to get:

1/12 = x
