Answer:
11 17/21 :)
Step-by-step explanation:
When you expand the equation, you will have
9x + 9=25 + x
Next you have to collect like terms
+x will go over the equality sign to become -x. The same applies to +9
9x - x=23 - 9
9x minus x is 8x
8x=14
Divide both sides by 8
x=14/8
You will have 1 6/8
6 is the remainder while 1 is the number of times 8 divided 14.
In decimal, it will be 1.75
Hope that helped. Good luck
Answer:
Part 1) An equation is 15.7=3p+1
Part 2) The approximate population in 1950 was 4.9 million people
Step-by-step explanation:
Let
p -----> the population in 1950 in million people
y -----> the population in 2003 in million people
we know that
y=3p+1 -----> equation A
y=15.7 ----> equation B
substitute equation B in equation A and solve for x
15.7=3p+1
3p=15.7-1
3p=14.7
p=4.9
therefore
The approximate population in 1950 was 4.9 million people
