-6x + 7x + 14 = 3
First, you add the variables x between each other so we can have one number with variable x:
x + 14 = 3
Then, subtract 14 from each side to get the variable x alone of a side, and its value on the other side:
x + 14 - 14 = 3 - 14
x = - 11
You can re-check your answer (very important):
-6x + 7x + 14 = -6(-11) + 7(-11) + 14 = 66 - 77 + 14 = -11 + 14 = 3

Answer:
9
Step-by-step explanation:
Divide them.
Answer: The least number of minutes that he has used his phone in a month is 1248
Step-by-step explanation:
Let m represent the number of minutes that he used his phone in a month.
For his phone service, Michael pays a monthly fee of $16, and he pays an additional $0.04 per minute if use. This means that if he used m minutes in a month, the total cost would be
16 + 0.04m
The least he has been charged in a month is $69.52. This means that
16 + 0.04m ≥ 65.92
0.04m ≥ 65.92 - 16
0.04m ≥ 49.92
m ≥ 49.92/0.04
m ≥ 1248 minutes
Answer:
5 = side a
3 = side c
angle B = 62 degrees
JK is side b
Use the Law of Cosines to find the length of side b.
b^2 = a^2 + c^2 − 2ac cos(B)
b^2 = (5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)
b^2 = (25 + 9) − 30 x 0.469
b^2 = 34 - 30 x 0.469
b^2 = 34 - 14.084
b^2 = 19.916
b = √19.916
b = 4.463
Rounded to the nearest tenth is 4.5 mm.

Step-by-step explanation:
12x+12 because you do the distribution property and this is how 3*9=27 3*4x=12x 3*-5=-15 27-15 = 12 so 12x+12 would be the answer it is really simple.
