Answer:
3.68
Step-by-step explanation:
I assume what you want ti find is the value of m?
You try to have an quation of the form "m=" where on the one side there is nothing but m.
so first, let's get rid of the bracket:
-2(4-m)=10
-8+2m=10
now, let's add 8 to both sides:
-8+8+2m=10+8
2m=18
and divide by 2:
m=9
and that's our solution
I can't really do the "show your work" part as well on a computer, but I'll do my best.
(a) $14.94 (2.49*6=14.94)
(b) $18.75 (150/8=18.75)
(c) $17.59 ($164.94 in total. So 182.53-164.94=17.59)
Hope this helps.
