Answer:
$15
Step-by-step explanation:
let the hourly rate of pay for Ben = B
let the hourly rate of pay for Judy = J
Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75;
4J + B = 75 ----- i
Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120
2J + 6B = 120 --- ii
Now, we should solve the expression;
Multiply equation ii by 2 and equation i by 1;
4J + B = 75 ----- i x 1 ; 4J + B = 75 -- iii
2J + 6B = 120 --- ii x 2 ; 4J + 12B = 240 ---iv
Now,
equation iv - iii;
11B = 165
B = $15
So, solving for J;
4J + B = 75
4J + 15 = 75
4J = 75 - 15 = 60
J = $15
7 and a half cups.
Step-by-step explanation:
Dvide 60 by 8
Step-by-step explanation:
Weight before diet: 208 pounds
After diet: 192 pounds
Difference in weight: 16 pounds
(16÷208)*100= 7.7%
13 is not the same as 1/3! The division symbol is not a symbol used to connect two numbers, it is used to find their quotient. For example, 6/2 would be like saying: You have 6 cookies, and 2 friends. How many cookies does each friend get? The answer is obviously not 62, it is 3! So, the exact quotient is 0.3 repeating. You could memorize this or use the fact that 0.9 repeating is 1.
