Answer:
$0.80
Step-by-step explanation:
percent times the original number equals the part
(%)(start or total cost)= (part of the total cost). you need to know the total cost, so you would fill in the part and the percent. 0.9x=0.72. you use x because you don't know what the total cost is. then you divide both sides by 0.9 to get x by itself and you get that x = 0.8, meaning that the present costs $0.80.
<span>DH = x + 2, HF = 2y, GH = 3x – 3, and HE = 5y + 1
DH = HF
</span>x + 2 = 2y
and
GH = HE
3x – 3 = 5y + 1
so now you have
x + 2 = 2y
3x – 3 = 5y + 1
re-write and simply
x = 2y - 2
3x = 5y + 4
substitute x = 2y - 2 into 3x = 5y + 4
3x = 5y + 4
3(2y - 2) = 5y + 4
6y - 6 = 5y + 4
y = 10
x = 2y - 2
x = 2(10) - 2
x = 20 - 2
x = 18
answer
x = 18 and y = 10
