-7(8x - 3) + x =
-56x + 21 + x =
-55x + 21
Answer:
8 is -7 and 9 is 108
Step-by-step explanation:
sorry that im late
2/3 - 3/4
x - 3
x= (2/3 * 3) / (3/4) = 2 * (4/3) = 8/3 = 2 and 2/3 of tablespoon of salt
Rate is ...
... r = d/t
Multiply both sides of the equation by time to find distance.
... rt = d
The equation for d is ...
... d = r·t
First combine like terms.
4n-2n = 2n
now it's a one step equation:
2n=18
divide both sides by 2
n=9
