I'm a little confused, it's about Combining like terms but I did don't understand​
ella [17]
2(-n-3)-7(5+2n)

First, you need to distribute the numbers in front of the parentheses to those in the parentheses. This means you multiply.

2 times -n= -2n

2 times -3= -6

-7 times 5= -35

-7 times 2n= -14n

This leaves you with

-2n -6 -35 -14n

Next, combine like terms.

(-2n) + (-14n)= -16n
(-35) + (-6)= -41

This gives you

-16n-41, which is B in your answer choices.

Hope this makes sense!! :)

2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?
Talja [164]

Answer:

There are 171 members in the club

Number of boys = 38

Number of girls = 133

Step-by-step explanation:

Let

x = total members of the club

Boys = 2/9x

if there are 95 more girls than boys

Girls = 2/9x + 95

how many girls are there in club?

Total members in the club = boys + girls

x = 2/9x + 2/9x + 95

x = 2+2/9x + 95

x = 4/9x + 95

x - 4/9x = 95

9x-4x/9 = 95

5/9x = 95

Divide both sides by 5/9

x = 95 ÷ 5/9

= 95 × 9/5

= 855/5

= 171

boys = 2/9x

= 2/9 * 171

= 342 / 9

= 38

Girls = 2/9x + 95

= 38 + 95

= 133

Total = 38 + 133

= 171

There are 171 members in the club

Number of boys = 38

Number of girls = 133
