Answer:

C. Julie drive 15.5 miles from her home to the grocery store. Julie drives the same path going back home. What is x, the total amount of miles traveled to the grocery store and back home?

Step-by-step explanation:

The situation in the 3rd option represents the equation, 15.5 = x/2.

Distance driven by Julie to the grocery store = 15.5 miles

Distance driven by Julie back home following the same path = 15.5 miles

Total amount of miles travelled to and fro the store, x, = 2*15.5

This means, the mile's covered going to the store or coming back home can be expressed as ½ the total amount of miles, x, covered. Which is: 15.5 = ½x

Therefore, the third option represents the equation, 15.5 = x/2.

Deon plans to ride a 20-mi bicycle trail. If his average speed is 10 mi/h, how many hours will the ride take? Part 1: Solve the
pentagon [3]

Answer:

The ride will take 2 h

Step-by-step explanation:

From the question,

Deon plans to ride a 20-mi bicycle trail, that is the total distance he plans to cover is 20-mi

Distance, d = 20 mi

Also, his average speed is 10 mi/h

rate of speed, r = 10 mi/h

To determine how many hours the ride will take,

From the formula,

d = rt

where

d is the distance covered

r is the average rate of speed

and t is the time.

We can solve for t, such

d = rt becomes

t = d/r

Now, from the question

d = 20 mi

r = 10 mi/h

∴ t = (20 mi) / (10 mi/h)

t = 2 h

Hence, the ride will take 2 h (hours)

Write the following decimal number in its equivalent fraction form. Show all work for full credit.
Zigmanuir [339]
<span>Let x=0.8888... 

x=0.8888 Start with the given equation 

10x=8.8888 Multiply both sides by 10. The goal is to move the decimal point to the next repeating portion (which is just one spot to the right) 



 Now subtract the equation x=0.8888 from 10x=8.8888 to get 
10x-x=8.8888-0.8888 

9x=8 Combine like terms. Notice how the decimal portions cancel out. 

x=8/9 Divide both sides by 9 to isolate x 

So the answer is x=8/9 which means that 8/9=0.8888 (where the 8's repeat)</span>
