Answer:
A)$ 45
B) $105
Step-by-step explanation:
Bag and a belt cost $255
Let bag = x
Let belt = y
X+y= 255 equation 1
Let total money be z first
Remaining money= z-255
X-30 = z-255
Y +15 = z-255
Equating the left side of the equation
X+30 = y+15
X-y= 45 equation 2
Solving simultaneously
X+y= 255
X-y= 45
2x = 300
X= 150
If x= 150
150-y= 45
150-45= y
105=y
Bag = $150
Belt = $105
Bag Is 150-105 more than the belt
150-105= $45

Answer:
21.2 ft³/h
Step-by-step explanation:
It's a units conversion problem. The conversion factors are each some representation of 1. That is, the numerator value is the same measure as the denominator value, but with different units.
10 L/min × (1 dm³/L) × ((1 ft)/(3.048 dm))³ × (60 min/h) = (10×60/3.048³) ft³/h
≈ 21.2 ft³/h

<em>Additional comment</em>
A decimeter (dm) is 10 cm, or 0.1 m. A cube with this dimension has a volume of 1000 cm³ = 1 liter. A foot is 30.48 cm, or 3.048 dm. I personally find it convenient to use dm as a metric unit of distance in problems involving volumes in liters.
Answer:

15 is how much you are paying consantly
I think if you do 0.25 Subtract 7.5 then you will get you answer then you can multiply the answer you have with the number 0.25 and see if yo can get 7.5
B. 24
-5/4xX-5=-35
The equation is a little bit tough to write out so that might take a little bit longer, I'm sorry.
