Answer:
26 year old
Step by step explanation:
Five years ago, John's age was half of the age he will be in 8 years.
this means that (x-5) = (x+8)/2
-----
solving for x, we get:
2 * (x-5) = x + 8
which becomes:
2x - 10 = x + 8
which becomes:
x = 18
-----
john is 18 years old now.
5 years ago john was 13
8 years from now john will be 26
13 = 1/2 * 26
Answer:
(X+8)(x-10
Step-by-step explanation:
The middle number is -2 and the last number is -80.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -2
Multiply together to get -80Try 8 and -10:
8+-10 = -2
8*-10 = -80
Fill in the blanks in
(x+_)(x+_)
with 8 and -10 to get...
(x+8)(x-10)
Answer:
I think the answer is 26.5
