X/0.5 = 24
X/0.5(0.5) = 24(0.5)
X = 12

Substitute the value of x = 2 to the equation:

I would use 100 as the denominator because it can not be simplified as a whole number
Answer:
$11
Step-by-step explanation:
This is because If you subtract 19 from 30 your answer will be 19.
A.
(7^2)^x = 1
(49)^x = 1
thus x = 0
B.
<span>(7^0)^x=1
(1)^x = 1
thus x can be any real number.
