Answer:
C
Step-by-step explanation:
you are adding
Answer: the store charged $40 for the bike helmet before tax.
Step-by-step explanation:
Let x represent the amount that the store charge for the bike helmet before tax.
If the sales tax rate was 8%, it means that the amount of tax that was charge is
8/100 × x = 0.08 × x = 0.08x
Monica paid sales tax of $3.20 when she bought a new bike helmet. This means that
0.08x = 3.2
Dividing the left hand side and the right hand side of the equation by 0.08, it becomes
0.08x/0.08 = 3.2/0.08
x = 40
Answer:
f'(x)= 2x - 14
Step-by-step explanation:
change f(x) to y y = 1/2x + 7
switch x and y x = 1/2y + 7
multiply everything by 2 to cancel the denominator 2x = y + 14
solve for y 2x - 14 = y
then change y to f'(x) f'(x) = 2x - 14
Answer:
50
Step-by-step explanation:
32 - 6 = 26
26 + 18 = 44
44 - 3 = 41
41 + 18 = 59
59 - 9 = 50
