X will equal 7.
4(5x-2)=2(9x+3)
20x-8=18x+6
20x-18x=8+6
2x=14
x=7

4(5x-2) = 2(9x+3)
20x - 8 = 2(9x+3)
20x - 8 = 18x + 6
20x - 18x - 8= 6
20x - 18x = 6 + 8
2x = 6 + 8
2x = 14
x = 7

In a volleyball game, Caroline served the ball over the net 16 out of 20 times. What percent did she not make her serve over the

brilliants [131]

16/20. We reduce that and get 4/5.

After this it's much simpler to chage it.

100 dividied by 5 is 20. (20,40,60,80,100)

So the 4th number (4/100)

is 80. 80%.

20% she didn't and 80% she did :) (100-80)
