First, you gotta simplify. There’s really nothing to simplify so just take it out of the parenthesis.
2x-8=2x-4
Now turn the -8 into a +8. Add it on each side.
2x=2x+8
Now turn the 2x on the right into a negative. Do the same thing you did with the 8.
Now it’s:
0 = 8
That means there’s no solution.

Answer: I hope this helps :)
Substitution: 45+15(6-1)
Simplify: 120
Step-by-step explanation:
Calculate within parenthases (6-1) =5 =45+15(5)
Multiply left to right 15(5)=75 =45+75
Add leftg to right 45+75=120
Answer = 120
The prime factorization of 70 is 2*5*7
Further explanation:
First of all let us define prime factorization
Prime factorization consists of all the prime multiples of a number i.e. the factors should also be prime numbers
Given number is 70
The multiples of 70 are
70 = 2*35 => 35 is composite number
70 = 5*14 => 14 is a composite number
70 = 7*10 => 10 is a composite number
70 = 2*5*7 => All factors are prime so
The prime factorization of 70 is 2*5*7

Answer:
520
Step-by-step explanation:
Past number of pupils: p
Increase of 57% = 1.57
Present number of pupils = 817
p x 1.57 = 817
p = 817 divided by 1.57 = 520.382
rounded to the nearest whole number = 520 (this is why the question says "about" how many...)
