Answer: 14 years
Step-by-step explanation:
Let the cat's age when it died = x.
Therefore, the child's age is 2 + x because he/she got the cat when he/she was 2 years old.
We can set up an equation.
x + (2+x) = 30
2x + 2 = 30
2x = 28
Therefore, x = 14
Answer:
12 feet
Step-by-step explanation:
If we use a rectangle. there would be 4 sides the length we can represent as x and the width would result as 3x. If we use the perimeter formula, we would get 8x. 8x would equal 96, the perimeter.
8x= 96
x= 12
The length would be 12

Answer:
0.05N - 0.1N + 1.7 (in dollars
1.7 - 0.05N (in dollars)
Step-by-step explanation:
Given :
Total number of coins = 17
Number of nickels = N
Number of dimes = 17 - N
1 nickel = 5 cent = $0.05
1 dime = 10 cent = $0.1
The amount of money :
(Value of nickel * number of nickels) + (value of dime * number of dime)
(0.05 * N) + (0.1 * (17-N))
0.05N + 1.7 - 0.1N
0.05N - 0.1N + 1.7
-0.05N + 1.7 = 1.7 - 0.05N
Answer=103 ounces
First we need a conversion equations to get from pounds to ounces
1pound=16ounce
2pounds=2*16=32 ounces of cucumber
3pounds=3*16=48 ounces of lettuce
Now that all of the vegetables are in ounces, we can solve for their total weight.
x=32+8+48+15=103 ounces
He bought 103 ounces of vegetables in total.
