Answer:
x=11
z=16
Step-by-step explanation:
5x+3z=70
3x+4z=64
2x-z=6
z=2x-6
5x+3(2x-6)=70
11x=88
z=2(11)-6
=16
here go the answer hope it help
first do the parenthesis
4x-3(3x+3x)>18
4x-3(6x)>18
4x-18x>18
-14x>18
I'm not sure if this helps but I tried
i cant see the picture its blocked
200% of 90 is 180.
13/20=65/100 so
.63 < 13/20 < 68%
r(14) = 29
r(x) = 3/2x+8
r(14) = 3/2*14+8 = 21+8 = 29
