H (x) = 5 x 2^-x
2^-x is the same as saying 1/2^x .
h (x) = 5 x 1/2^x
h (3) = 5 x 1/2^3
= 5 x 1/8
= 5/8
Therefore h (3) = 5/8
Answer:
it would be C.
Step-by-step explanation:
if you have 7 dogs and take away 7 you have 0 dogs.
Well, the speed is 45mph (divided 270 by 6). It would take her 9 hours (divided 405 by 45).
Answer is -3/4
Start with putting parentheses on the given numbers for these variables
Remove parentheses(When there is a in front of an expression in parentheses, the expression remains the same)
Reduce the numbers with the greatest common factor(3)
Calculate the difference 1 -7/4
Alternative form: -0.75
It's just an equation, the number you're looking for is X, and then turn the words into an solvable equation with respect to X.
7X + 3 = 39 - 2X
9X = 39 -3 = 36
X = 4
