Answer:
Step-by-step explanation:
u had 11 and u spent 7
7/11 <=== the fraction of money u spent is 7 out of 11
Let the number of adults be x, then number of male students is 1 + 7x and the number of female students is (1 + 7x)/2.
x + 1 + 7x + (1 + 7x)/2 = 82
2x + 2 + 14x + 1 + 7x = 164
23x = 164 - 2 - 1 = 161
x = 161/23 = 7
Therefore, number of male students is 1 + 7(7) = 1 + 49 = 50
and the number of female students is 50/2 = 25.

Answer:
Let's simplify step-by-step.
3−3/4x−1/4x−7
=3+ −3/4x+ −1/4x+ −7
Combine Like Terms:
=3+ −3/4x+ −1/4x+ −7
=(−3/4x+ −1/4x)+(3+ −7)
=−x+ −4
Answer:=−x−4
Step-by-step explanation:
answer:-4
Answer:
10x^2-25x-35
Step-by-step explanation:
FOIL means first, outer, inner, and last.
The first term of each pair is 2x and 5x.
The outer term of each pair is 2x and 5.
The inner term of each pairs are -7 and 5x.
The last term of each is -7 and 5.
Now we just have to multiply the terms I pairs above:
First: (2x)(5x)=10x^2
Outer: (2x)(5)=10x
Inner: (-7)(5x)=-35x
Last: (-7)(5)=-35
------------------------------Add the terms:
10x^2-25x-35
