Answer:
m = 56
Step-by-step explanation:
So, this is a standard one-step equation so we do the inverse thingy:
8 x 7 = 56
And because 56/7 = 8
m = 56
The answer is 61.
66 + 7 = 73
13 + 8 = 21
52 + 9 = 61 (The answer)
10 + 10 = 20
Answer:
n = m - a
Step-by-step explanation:
Given:
a = m − n
Where,
Actual cost of the item = a
Original price of the item = m
Amount of Coupon = n
Solve the formula for the amount of the coupon
Making n the subject
a = m − n
Subtract m from both sides
a - m = m - n - m
a - m = - n
Divide both sides by -1
(a - m) / -1 = -n / -1
- a + m = n
Can also be written as
n = m - a
5. since .6 is greater than 5, we round up.
