Answer:
Xena earns $144 per a week.
Step-by-step explanation:
Harry earns - $ h
Xena earns - $ x
George earns -$ g
Harry earns $45 a week more than Xena. h= x+45
George earns $18 a week less than Xena. g = x - 18
If Harry earns the same amount in two weeks that George earns in three weeks
2h = 3g
So, we have the system of 3 equations:
h= x+45
g = x - 18
2h = 3g (*)
Substitute values of h and g into equation (*)
2(x+45) = 3(x-18)
2x + 90 = 3x - 54
90+54 = 3x- 2x
x= 144
This is basically saying how much of the pizza did Tashia and Jay both ate, thus combining their portions together.
1/3 + 3/8 = fraction of pizza eaten
To add fractions, you must have a common denominator. Which is 24 in this case because 3*8 = 24.
So you multiply 1/3 with 8 and multiply 3/8 with 3.
1/3*8= 8/24
3/8*3= 9/24
Now you add the fractions.
8/24+9/24= 17/24. You add the numerator, the denominator stays the same.
17/24 of the pizza was eaten.
3/4 of the total students = 1230...
3/4x = 1230
x = 1230 * 4/3
x = 4920/3
x = 1640 <=== total students
