Answer:
1. $2.50
2. 2/5lb
Step-by-step explanation:
1. 2lbs=$5.00 so that means 1lb=$2.50.
2. 1lb=$2.50 so that means 1/5lb=$0.50 which you can then conclude that 2/5lb=$1.00
Answer:
4 Years
Step-by-step explanation:
With the simple Interest formula you take the starting money, multiply it by the interest rate and then multiply that by how many times interest is given. Since the question mentions years I'm assuming the interest is given annually.
Here we are missing a piece of that but have the final answer. Anyway, if we say the starting money is P, the interest rate is R and the number of times interest is taken is T and the final amount is A we can plug in
PRT = A
7511 * .02 * T = 600.88
T = 600.88/(7511 * .02)
T = 4
So that's 4 years

Answer:
Explanation:
12x = 48 - 8y
10x + 8y = 38
———————
12x + 8y = 48
10x + 8y = 38
———————
12x + 8y = 48
-1(10x + 8y = 38)
————————
12x + 8y = 48
-10x - 8y = -38
————————
2x = 10
x = 10/2 = 5
If x = 5 then:
10x + 8y = 38
10(5) + 8y = 38
50 + 8y = 38
8y = 38 - 50
8y = -12
y = -12/8
y = -3/2
Therefore, x = 5 and y = -3/2
