13.5 tablespoons of concentrate need to be mixed with 9 gallons of water.
Given that the directions for a weed spray concentrate state that 3 tablespoons of the concentrate should be mixed with 2 gallons of water, to determine how many tablespoons of concentrate need to be mixed with 9 gallons of water, the following cross multiplication calculation must be performed :
- 2 = 3
- 9 = X
- 9 x 3/2 = X
- 27/2 = X
- 13.5 = X
Thus, 13.5 tablespoons of concentrate need to be mixed with 9 gallons of water.

x + x + 4 = 20
x + x = 16
16 / 2 = 8
Mike is 8, and Mark is 12.
Answer:
6.
Step-by-step explanation:
2.3 repeating = 2 1/3
So 3 2/3 + 2 1/3
= 5 + 1
= 6.
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
First, add 9 to both sides
3/4x - 9 (+9) = 27 (+9)
3/4x = 36
Next, multiply 4/3 to both sides
(4/3)(3/4)x = 36(4/3)
x = 36(4/3)
Simplify.
x = 12(4)
x = 48
48 is your answer for x.
hope this helps
