Answer:
Arnez is 4. Andell is 13. Marianne is 7.
Step-by-step explanation:
Let x represent Arnez's age. If we write out an equation, we end up with this:
24 = (9 + x) + (x + 3) + x
24 = 9 + x + x + 3 + x
24 = (x + x + x) + (9 + 3)
24 = 3x + 12
24 - 12 = 3x + 12 - 12
12 / 3 = 3x / 3
4 = x
C. As that’s the same as 15>8.
Answer:
22.2 pounds and 1g = 7.4p
Step-by-step explanation:
Lets go in an inverse sense, finding firstly the constant variation and then the weight of 3 gallons.
The constant variation is the relation between gallons of diesel volume and pounds of diesel weight. For thise we would like to find how many pounds of diesel weights 1 gallon. We have the following equality:
5 gallons = 37 pounds
Now, lets divide both sided by 5, as we know the equality will still:
5/5 gallon = 37/ 5 pounds
1 gallon = 7.4 pounds
So, this is the constant variations: every extra gallons weights 7.4 pounds. We could also do this in terms of pounds, which means, parting from:
5 gallons = 37 pounds
Divide both sides by 37:
5/37 gallons = 1 pound
0.081 gallons = 1 pound
Every extra pound means 0.081 more gallons.
Now, as we want the weight of 3 gallons we can use our first relation and multiplying by 3:
1 gallon = 7.4 pounds
3 gallons = 22.2 pounds
