(b)+(b+45)=215
b = # of boys
there are 45 more girls than boys and 215 students total.
minus 45 on both sides leaving you with
(b)+(b)=170
combine like terms leaving you with
2b=170
divide both sides by 2
b=85
there were 85 boys
85+45=130
(the 45 for the # of girls more than boys)
there were 130 girls.
Since percent is mostly common as a fraction with a denominator of 100, we'll convert the fraction 37/50 to x/100. To convert 50 to 100, you multiply 50 by 2, so you are also going to multiply 37 by 2, which is 74. Now we have the fraction 74/100, so now since the fraction is over 100, we can convert it to a percentage.
So 74% is equal to the fraction 37/50.
Answer:
x= 1/3
Step-by-step explanation:
15x+7=12
Subtract 7 from both sides, we got:
15x + 7 - 7 = 12 - 7
15x = 5
Divide both sides by 5, we got:
15x / 5 = 5/5
15/5*x = 1
3x = 1
Divide bith side by 3, we gotL
3x/3 = 1/3
1x = 1/3
x = 1/3
Hope this help you :3
The function g(x) factors as
g(x) = (x-4)(x-6)
so the x-intercepts are at x=4 and x=6.
The appropriate choice is
(4, 0) and (6, 0)
Answer:
I feel like my answer is wrong but all of them are false
first one: it's between 0 and 5
second one: it's between 5 and 10
third one: it's between 10 and 15
but you could also say that they are all true because between the numbers they gave, they are doing what they said
