That is the answer. hopefully I can help you.
198=-4x+2(-6x+3), 198=-4x-12x+6, 198=-16x+6, collect the like terms, 198-6=-16x, 192=-16x, divide both sides by -16, 192/-16=-16x/-16, x=-12
<span>906.25</span>
<span>because 720 multiplied by 1.25 equals 906.25</span>
1) x+17=20
x-10=30
2) x/4=20
x/30=2
3) 4(x+5)=40
4) x+3.2=6
5) A pizza place sells pizza for $5 per box. If I had $20 how many pizzas can I buy in all? (5x=20)
Hope this helps! Have a wonderful day.
Answer:
9
Step-by-step explanation:
The equation is
9x + 1.50 = 82.50
You must isolate the 9x , to do so you have to subtract 1.50 from both sides.
9x + 1.50 = 82.50
-1.50 -1.50
9x = 81
isolate the variable (x), to do so you have to divide both sides by 9
9x = 81
/9 /9
=
x = 9
