Answer:
x = 25
Step-by-step explanation:
2/5x - 1 = 9
Add 1 to both sides
2/5x = 10
Multiply both sides by the reciprocal of 2/5, which would be 5/2
x = 25
Answer: X= -7
Step-by-step explanation: A negative time a negative is a positive so -12x-7 is equal to 84. 84 plus 16 is equal too 100.
Answer <span>B.X= 3 1/8
</span><span>X+7/8=4
x = 4 - 7/8
x =3 8/8 - 7/8
x = 3 1/8</span>
You can just plug in 16 for X
F(16) when F(x)=4x-8
F(x)=4(16)-8
F(x)=64-8
F(x)=56
