So first you have to move the -2 over to the opposite side.
8(9x-4)=3+2+2
Then you can simplify the right side
8(9x-4)=7
Then you distribute
8*9x=72x
8*-4=-32
so now you have...
72x-32=7
Then you move the 37 over
72x=39
Then you divide by 72 to isolate x
x=39/72 or x= 13/24 or <span>x=0.54167</span>
Just think 200% = 2x, so 2x of 18 = 36. Now for the 20%. Thats one fifth, so just do 18/5 and you have your answer when you add those together
Answer:
It looks like on step c he took away 10 instead of adding 10
He needs to learn >10 new plays, but has already learned 4. Therefore, the inequality is x+4>10, where x is the amount of new plays he must learn, 4 is the amount he has already learned and >10 (more than 10) is the amount of plays he needs to learn in total.
x+4>10
x>6 is the solved inequality
