The answer is A 3x(32-19)

Reasoning: Triple the difference of 32 and 19 would be a 3x multiplication of 32-19, you need parenthesis in order to do 32-19 first because of PEMDAS. SO the answer would be 3x(32-19 because none of the other options would show the equation correctly.

Select all the equations where z=5z=5z, equals, 5 is a solution.

Serhud [2]

Answer:

A, D and E

Step-by-step explanation:

A.

$8 = z + 3$

Subtract 3 from both sides

$8 -3 = z + 3-3$

$5 = z$

$z = 5$

B.

$z - 1 = 6$

Add 1 to both sides

$z - 1+1 = 6 + 1$

$z = 7$

C.

$20 = \frac{40}{z}$

Multiply through by z

$z * 20 = \frac{40}{z} * z$

$20z = 40$

Divide through by 20

$\frac{20z}{20} = \frac{40}{20}$

$z = 2$

D.

$12z = 60$

Divide through by 12

$z = 60/12$

$z = 5$

E

$12 + z = 17$

Subtract 12 from both sides

$-12 + 12 + z = 17 - 12$

$z = 5$

Hence:

You are driving 2760 miles across the country. During the first 3 days of your trip, you drive 1380 miles. If you continue to dr

prohojiy [21]

The entire trip will take 6 days.

(Encircle this answer, as said on the directions)

Step-by-step explanation:

We know that the first three days of the trip, we traveled 1380 miles.

Find the UNIT RATE of MILES PER day:

1380/3 = 460

Unit rate = 460 miles per day

If we were to drive at this (460 mi per day) rate EACH day and the whole journey takes 2760 miles across the country.

FInd the NUMBER of DAYS of the ENTIRE TRIP:

2760/460 = 6

It will take us 6 days to drive to the destination.
