(part/whole)*100%=20%
(360/whole)=20/100
360/whole=0.2
whole *0.2=360
whole =360/0.2 =1800
PQ + QR = PR
7 + 10 = PR
17 = PR
The answer is 17
Answer:
-9/2 or -4.5
Step-by-step explanation:
-1/2 - 4
= -9/2 or -4.5
Basically, simplifying variables is the same as regular equations (like 5-3=2 and 5x-3x=2x)
So 7x-x is the same as 7x-1x which equals 6x
And -3p+6p is the same thing as -3+6 but with a p. With this in mind, the answer is 3p
Hope this helps
