Well standard form is Ax+By=C, so just move the -7x to the front so -7x+47=16
Answer:
=s
Step-by-step explanation:
The area of a square can be found by multiplying two of the sides of the square. So P=s*s, of "Perimeter equals side length time side length". We also know that all the sides of a square are the same side, so the perimeter of the sqaure can be found using the square by doing p=
.
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:
The answer for x=2 is, 15. And the answer for x=-2 is, -1.
Step-by-step explanation:
When you input x=2, it turns out to be (4.2)+7 which is 15. When you input x=-2, this will lead us to (4.(-2))+7 which is -1.
