So there are two potential ways you could do this. First just multiple the g=7 into the equation and then add. Or another possibility is to first add the 14g and 3g to get the 17g and then multiply it by the g value and subtract 98. So if we combine the g's and then multiply it by 7, the 17g becomes
. So now subtract 98 from 119,
. So the overall answer to the expression is 21 when g equals 7.
Let x is number of girls going (x>0).
Since the bus cost 360, each of them paid:
If they got 3 more, each would pay:
According to statement:
- 6 =
⇒(360 - 6x)(x+3) = 360x
⇒360x - 6x^2 +3*360 -18x = 360
⇒6x^2 + 18x - 3*360 = 0
⇒6(x-12)(x+15) = 0
⇒x = 12 (because x > 0)
Thus, 12 girls went.
No, because on the Moon, the gravitational pull is not as strong as Earth's. If he were on Earth with that space suit, he would have hard time moving because of Earth's strong pull.
I hope this helps! :D
3x-9=0
3x=9
x=3
hoped that helped
