VikaD [51]

Answer:

40+2s=60-3s

Step-by-step explanation:

The red balloon starts 40 feet off the ground and rises 2 feet per second. This means the height of the red ballon is 40+2s.

The blue balloon starts 60 feet off the ground at starts falling 3 feet per second. This means the height of the blue balloon is 60-3s.

Because we want to find out when the balloons will be the same height, we set them equal to each other.

40+2s=60-3s

Answer:

Step-by-step explanation:

follow a few exponent rules and you can figure this out

when expoenents are to the power of something you can mutilply the expoents.. and when there is a minus sign in the exponent.. it's like the reciprocal $x^{-2}$ is 1/ $x^{2}$ soooo...

mutilply the -2/3 by each of the exponents in the question the 8 is tricky b/c it has an invisible 1 on it :o

= $8^{-2/3}$ $w^{-14/3}$ $x^{10/3}$ $y^{-6/3}$ $z^{18/3}$

= 1/ $\sqrt[3]{8*8}$ * 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$

= 1/ $\sqrt[3]{64}$ * 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$

= 1/4* 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$
