First expand the brackets by multiplying each thing inside the brackets by 2:
4x−10=6x+4. then minus the 4x so there are only x 's on one side:
−10=2x+4. then minus the 4 so there are only numbers on one side and x 's on the other:
−14=2x. then divide by 2 to get the value of x
Answer:
A.
Step-by-step explanation:
We fill in the following formula:

So in this case we get

Therefore the answer is 85%
7k/3 = 21
x 3 x3
7k = 63
/7 /7
k = 9
(7(9)/3 = 21 = 63/3 = 21 = 21 = 21)
180÷(300-30)×9+199
180 ÷ (270)×9+199
180÷270=
.66×9=
5.94+199=
204.94, approximately 205
