If these are the choices:
A. 8m – 38

B. 8m + 7

C. 8m + 31

<span>D. 2m – 38

Solution:

6(2m - 1) - 4(m + 8)

distributive property of multiplication:
6(2m) + 6(-1) -4(m) -4(8)
12m - 6 -4m -32

combine like terms:
12m - 4m - 6 - 32
8m - 38  choice A. </span>

LekaFEV [45]

Answer:

There were 300 videos.

Step-by-step explanation:

Since there are 24 videos that got awards, and that's only 8% of the total videos, you put those together. We want the number of 100% of the videos. I would solve this by setting up a ratio and solving for x. This is would look like:

\frac{24}{8} =\frac{x}{100}  

In order to get to 100, you must multiply 8 by 12.5. Therefore, you can multiply 24 by 12.5 to complete the ratio. That would make the ratio look like:

\frac{24}{8} =\frac{300}{100}

Therefore there are 100% of the videos in the contest is 300.

Noah wants to save $700 in 10 months. He thinks he can earn $11 interest. Why is it reasonable that he should save $69 a month?
konstantin123 [22]
Alright not entirely sure but here is my theory 
69x100=690 if he has the 11$ interest rate it would be 701$ in 10 months 
so he would have 1 more dollar  <span />

The Murphy family is on a road trip. On the first day, they traveled 30% of their total distance. On the second day, they travel
Otrada [13]

Answer:

5/12

Step-by-step explanation:

Total distance travelled = 30% + 1/4

To add these numbers, convert 30% to fraction

30% = 1/3

1/3 + 1/4 = 7/12

Remaining distance = 1 - 7/12 = 5/12

Aubrey and Charlie are driving to a city that is 120 miles from their house. they have already traveled 20 miles ,and they are d
Phoenix [80]

Answer:

The linear function is y=50x+20

The reasonable domain is 0\ hours \leq x\leq 2\ hours

Step-by-step explanation:

Let

x ----> the time in hours

y ---> the distance in miles

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem

The slope is m=50\ \frac{miles}{hour}

The y-intercept is b=20\ miles

substitute

y=50x+20

<em>Find the domain for x</em>

For y=120 miles

Find the value of x

substitute the value of y in the linear equation and solve for x

120=50x+20

50x=120-20

50x=100

x=2\ hours

therefore

The domain is the interval [0,2]

0\ hours \leq x\leq 2\ hours
