You multiply the numbers and add the variable's exponents.
Answer:
4$ for large 3$ for a small
Step-by-step explanation:
(1/5) / 4.5 = 2 / m....1/5 mile to 4.5 minutes = 2 miles to m minutes
cross multiply
(1/5)(m) = (2)(4.5)
1/5m = 9
m = 9 * 5/1
m = 45 minutes <===
For 6 hours charges $330
for 9 hours charges x
---------------------------------
x = 9*330/6 = 495 so choice C. is right
Answer:
A. -10
Step-by-step explanation:
I think you would do like this:
y=2x-5
what about 2y(2x-5) times 2)
so 2y=4x- (-10)
