=====================================================
Explanation:
The mixed number 4 & 1/2 converts to the decimal form 4.5
The unit price is 27/(4.5) = 6 dollars per kilogram

Dividing both parts of that ratio by 4.5 will lead to
1 kg : 6 dollars
X=1 because when u put it in then u will find out.y=-1
Answer:
4x +3y=36
Step-by-step explanation:
Equation of line is (y-y1) = m(x-x1)
(y+4) = (-4/3)(x-12)
3(y+4) = (-4)(x-12)
3y +12 = -4x + 48
4x+3y = 36
Answer:
The more expensive book cost $90, the other two combined cost $60.
Step-by-step explanation:
x = cost of more expensive book
y = subtotal cost of the other books
x = 50% more than y, so x = 1.50y = 1.5y
x + y = total cost = $150
1.5y + y = 150
y = 150/2.5 = 60
x = 1.5y = 1.5(60) = 90
Answer:
60
Step-by-step explanation:
15 times 5 is 75 75 minus 15 is 60 so the answer is 60
