Answer:
-56
Explanation:
From the equation:
0.75(x + 20) = 2 + 0.5(x - 2)
Open brackets
0.75x + 15 = 2 + 0.5x - 1
Collect like terms
0.75x - 0.5x = 2 - 1 - 15
0.25x = - 14
Divide both sides by 0.25
x = -56
I think so I never took one in 8th grade tho
B) -4
5b=6a+16
9a=7b-20
b=(6/5)a+(16/5)
9a=7((6/5)a+(16/5))-20
9a=(42/5)a+12/5
(3/5)a=12/5
a=4
5b=6(4)+16
5b=24+16
5b=40
b=8
3(4)-2(8)
12-16=-4
Answer:
To make a cheer dance routine in a solo performance I would still do the usual sections a group routine has, without the ones that are done with a partner. For example, I would have an opening to show my abilities, then I would do a standing tumbling sequence and finally different jumps. I would mix all these sequences with different dance moves.
hope that helped <3
