Answer:
The third one, x+(x+1)+(x+2)=-21 because x, x+1 and x+2 are three consecutive numbers.
You just have to make 36/10 into 3 6/10. After that, it would become 3.6
Take the total amount which is $20 and multiply by the reciprocal of 120% (5/6)
$20*5/6=$16.66= most expensive item that you can order
No is the answer. If she works 20 hours at Kroger ($8 x 20 hours = 160) and 15 hours babysitting($15 x 15 hours = 225) 160 + 225 = $385
-8(3 - s) = 32
So you expand the brackets
-24 + 8s = 32
And then solve
+ 24
8s = 56
÷ 8
s = 7
Hope this helps!
