X=3 y=-2
4x - 6y
4(3) - 6(-2)
12 - (-12) (two negatives cancel out)
12 + 12 = 24
answer: 24
Given:
Lacy work 15 hours last week and she was paid $127.50.
To find:
The hourly pay of Lacy.
Solution:
We have,
15 hours pay = $127.50
To find the hourly pay of Lacy, we need to divide total pay by number of hours.



Therefore, the hourly pay of Lacy is $8.50.
Answer:
Rational numbers
Step-by-step explanation:
This is because you can write it as a fraction, percentage, and it stops at some point.
H=-3x^2-6x+5 subtract 5 from both sides
h-5=-3x^2-6x divide both sides by -3
(5-h)/3=x^2+2x halve the linear coefficient, square it, add it to both sides....
(2/2)^2=1 add 1 to both sides...
(5-h+3)/3=x^2+2x+1, now the right side is a perfect square...
(8-h)/3=(x+1)^2 multiply both sides by 3
8-h=3(x+1)^2 divide both sides by -1
h-8=-3(x+1)^2 add 8 to both sides
h=-3(x+1)^2+8
h(x)= -3(x+1)^2+8
Second answer down from the top :)
If both containers of orange juice are being sold at the same unit rate, the ratio of ounces to dollars would be the same for the two.
solve the equation by making an inequality:
96 oz. is to $4.80, as 128 oz. is to x
96/ 4.80 = 128/ x
cross multiply 128 and 4.80 to get 614.4
next divide the 614.4 by 96
to get an answer of 6.4
answer: $6.40
