2(p+1)=24
divide both sides by two
p+1=12
subtract 1 from both sides
p=11
Answer:
Step-by-step explanation:
5x + 38 = 8x - 19
by transposing method,
5x - 8x = -19-38
-3x = -57
3x = 57
x = 57/3
x = 19

Step-by-step explanation:
let the price be x before increased.
After it is increased then it becomes 1.03x
i.e. 1.03x= 720
x=699.03 which is the price after it is increased.
M + w + c = 2838
w = 3c + 5
m = 4w - 3......4(3c + 5)- 3 = 12c + 20 - 3 = 12c + 17
(12c + 17) + (3c + 5) + c = 2838 .....combine like terms
16c + 22 = 2838
16c = 2838 - 22
16c = 2816
c = 2816/16
c = 176 <==== children
w = 3c + 5
w = 3(176) + 5
w = 533 <=== women
m = 12c + 17
m = 12(176) + 17
m = 2129 <=== men
