What is the value of x? X-3/7 equals 4

Mathematics

Greeley [361]3 years ago

For this case we must find the value of the variable "x" of the following expression:

\frac {x-3} {7} = 4

So:

We multiply by 7 on both sides of the equation:

x-3 = 4 * 7\\x-3 = 28

We add 3 to both sides of the equation:

x = 28 + 3

Equal signs are added and the same sign is placed.

x = 31

Answer:

x = 31

Step-by-step

X-3/7 = 4

take -3/4 to the other side

x = 3/7 + 4

x = 3/7 + 28/7 (<=another way to write 4)

x = 31/7

PLEASE HURRY WILL GIVE BRAINLIEST A truck can be rented from Company A for $90 a day plus $0.30 per mile. Company B charges $70
rjkz [21]

Answer:

  40 miles a day

Step-by-step explanation:

The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:

  A: 90 + 0.30·40 = 102

  B: 70 + 0.80·40 = 102
