To find out the last operation, we must solve the entire problem.
We are given:
Let's simplify the signs so they don't clutter our equation.
We always need to be sure to use PEMDAS. Since there is no expression to solve in parenthesis and no exponents are present, we will move on to multiplication. We can multiply -9 and -6 in the denominator. When we do that, we get:
Next, all you need to do is combine like terms in the numerator and the denominator.
Simplify.
To answer the question, the last operation to be performed when finding the value would be division.
Answer:
3+6n=
Step-by-step explanation:
Answer:
a. k = 6 b. $66
Step-by-step explanation:
= 6 k is 6
(I know where this question goes so I'll do the rest)
b.
y = 6x
y = 6 · 11
y = 66
The dry cleaner would charge $66

Answer:
- 64 weeks
- 4 months
Step-by-step explanation:
1. Let y represent gallons in the tank, and x represent number of weeks.
<u>tank 1</u>
y = 256 -3x . . . . . starts with 256 gallons, loses 3 per week
<u>tank 2</u>
y = 384 -5x . . . . . starts with 384 gallons, loses 5 per week
The amounts in the tanks will be equal when the y-values are equal.
y = y
256 -3x = 384 -5x
2x = 128 . . . . add 5x-256
x = 64 . . . . . . divide by 2
The amount of water in the two tanks will be equal after 64 weeks.

2. Let s and f represent the total cost of membership at Silver Gym and Fit Factor, respectively. Let x represent the number of months of membership.
s = 25 +30x
f = 65 +20x
The costs are the same when s=f.
s = f
25 +30x = 65 +20x
10x = 40 . . . . . . subtract 25 +20x
x = 4 . . . . . . . . . divide by 10
The two memberships will be the same price after 4 months.
Answer:
19.5
Step-by-step explanation:
half the total of each value for the 2 pairs of letters
bd=24÷2=12 which would be your d
be=15÷2=7.5 which would be e
