MAXImum [283]2 years ago
4 0

Answer:

In the first step, there is an issue when distributing the -3 to the terms inside of the parentheses. When multiplying the -3 to the -5, you would get an answer of +15, not -15.

The full correct process is:

(4m + 9) - 3(2m - 5) = 4m + 9 - 6m + 15

                                = 4m - 6m + 9 + 15

                                = -2m + 24

Josie took a road trip. She drove for 45 minutes at 70 miles per hour. Then she drove 15 minutes at 20 miles per hour. How far d
Hunter-Best [27]

Answer:

Therefore Josie drove  57.5 miles.

Step-by-step explanation:

Speed: The ratio of distance to time.

To find the distance we use the following formula

Distance= time \times speed

Given that Josie drove 45 minutes at 70 miles per hour.

45 \ minutes= \frac{45}{60}\ h=\frac34\ h

In 45 minutes, she traveled  = (70\times \frac34) \ miles

                                                =52.5 miles.

The she drove 15 minutes at 20 mile per hour.

15 \ minutes= \frac{15}{60}\ h=\frac14\ h

In 15 minutes, she traveled =(20\times \frac 14) \ miles

                                            =5 miles

Therefore Josie drove (52.5+5) miles= 57.5 miles.

How do you work out 5/6y-2=8
aliya0001 [1]
5/6y-2=8
       +2  +2
Add the reciprocal to cancel out the twos andd 8+2=10
so you have left 5/6y=10 and you'll take the reciprocal of 5 divided by 6 times five and cancels the 5/ out and also multiply 10*5 and you're left with 6y=50 then you just divide by six and there you go you have y=12

hope this helped

Solve for u.<br> 36 – 9u = 27
strojnjashka [21]

Answer:

u = 1

Step-by-step explanation:

First, we can use inverse operations to help.

27 + 9u = 36

Next, we can start replacing u with numbers to find which number fits in u.

27 + 9(1) = 36

27 + 9(2) ≠ 36

27 + 9(3) ≠ 36

Now, we know that u = 1
