Let p = pictures only
let f = pictures with frames
p + f = 100
5p + 10f = 875
Solve for one variable in the first equation then plug into the second
p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75
75 pictures with frames were sold
Answer:
2.2
Step-by-step explanation:
Given
Distribute 9 on the left hand side and 5 on the right hand side (distributive property of addition)
Add 36 to both sides (addition property of equality)
Subtract 15h to both sides (subtraction property of equality)
Divide both sides by -6 (division property of equality)
We are asked to solve for the simplified expression of rectangle ABCD and the restriction on x. The solution is shown below:
L = 3X + 92X -4 = 95X -4
W =5X + 5X +3 =10X +3
The formula is Area = L*W
Area = (95x-4) * (10x +3)
Area = 950x² + 285x - 40x -12
Area = 950x² + 245x -12
x should be greater than zero
