-13 (q + 4) = 7q + 16

I think to solve it you do this first:

-13q + -52 = 7q + 16

And then I think you do:

-6q + -36

And thats all I can remember sorry ):

That -6q + -36 might be the answer I think (:

Hope I could help (:

Simplify the expression -3x+5y-2+7x-8y+5

Natasha2012 [34]

To simplify this expression we need, at first, to find like terms.

-3x+5y-2+7x-8y-3x+5 = (-3x+7x)+ (5y-8y) -2+5 = 4x + 3y +3

4x + 3y +3 is the answer.

Based on the image and stated scale, what is the value of y?

GenaCL600 [577]

PLEASE HELP !!!!! ASAP

Well, the first ballon appears to be halfway to the second (the second being 300 meters from the ground) so the first, being at approximately 150 meters, both away from the ground and the balloon, would have to travel a further 150 meters.

Number 13 is what I need done

Nadusha1986 [10]

Instead of using an = sign we use $\leq$ becuase its less than or equal to 100 dollars.

The equation of the line is y=10x+7

sub in 100 for y and the inequallity sign

10x+7 $\leq$ 100

solve so x is isolated

10x $\leq$ 93
x $\leq$ 9.3

technically the answer is 9 because you cant buy a fraction of a CD

Answer:

x=27

Step-by-step explanation:

The formula for the volume of a pyramid is L*W*H/3

We know all three, being x, x, and x/9

So after we plug those in, we see that x^3/27 = 27

then solving for x we get √27*27 which is 27
