#4) 4x+8 is same as choice 2) 4(x+2), 4) 2(2x+4), 5) 8+4x(order is not important in this case because the result stays the same), 7) 1/2(8x+16) ( divide 8 by 2 and also 16 by 2) #5) 7x+2x+6y=3(3x+2y) ( first we need to add 7x and 2x. 7x+2x equals 9x so does 3x multiplied by 3.)

O=2a+2,  

o/2-a/2=4  this is your system of equations, 

It you wish to solve for apples, then simply substitute o from the first equation into the second equation...

(2a+2)/2-a/2=4  multiply both sides of the equation by 2

2a+2-a=8  combine like terms on the left side

a+2=8  subtract 2 from both sides 

a=6   

So Javier has 6 apples in the basket.

Which graph has a slope of 1/2?
ryzh [129]
A slope of 1/2 means for every two units to the right we move up one.

We have to be careful here because the graphs don't always use the same scale for x and y.

The bottom left uses the same scale and does indeed go two units to the right for every unit up, so that one is the answer.
