Answer:
36
Step-by-step explanation:
(7+ )(7- )
this is in the form of a^2-b^2 formula
a^2-d^2=(a-b)(a+b).so write,
(7)^2-( )^2
=49-13
=36
3oo tickets <span>÷ 2 =
150 tickets
150 tickets </span><span>÷ 3 =
50 tickets
Your answer is 50 people</span>
First simplify:
15h/5h becomes 3 (because 15h & 5h are divisible by 5h)
3+10h/5h+25/5h=x+y+5/h
10h/5h becomes 2 (because 10h & 5h are divisible by 5h)
3+2+25/5h=x+y+5/h
25/5h becomes 5/h (because 25 & 5 are divisible by 5)
3+2+5/h=x+y+5/h
Add 3+2=5
5+5/h=x+y+5/h
subtract -5/h from both sides, which cancel's each one out.
5=x+y
Now depending on whether you are solving for x or y, subtract the opposite, leaving the one you are solving for left by itself, as the one you subtract will cancel itself out on the right side.
5-y=x or x=5-y
or
5-x=y or y=5-x
8(5) + 1
40+ 1 = 41
41 is the answer.
