65;100 which is equal to 13;20
The total amount of girls in the gymnastics class is 65.
The total number of students is boys+girls (65+35) which is equal to 100
the ratio would be 65;100
if you simplify that, it would be 13/20
Hope this helps :)
Answer:
parallel slope = , perpendicular =
Step-by-step explanation:
to find slope, formula:
:
:
if parallel, same slope, so slope = 13/8
if perpendicular, slope = -1/n = -1/13/8 = -8/13 is the perpendicular slope.
(btw if i write 4x^3 it means 4x to the power of 3)
1) (2x+3)(x-2)
2x^2 -4x + 3x -6
2x^2 -x -6
2) x^2 +10x +24
(x+12)(x-2)
3) 6x^2 -13x +6
(2x )(3x ) not sure on this one
4) x^2 +8x +15
(x+3)(x+5)
x= -3 x=-5
5) x^2 -4x -45
(x+5) (x-9)
x=-5 x=9

Answer:
You can always compare to cost together but the big thing to look for is that you could be spending less for more on a product or the other way around, spending more for less product. you always want to go with the product that you are spending less money to get more product out of it.

and
50 pencils for 10 dollarsthan
you would want to buy the second pack of pencils because you are getting each pencil for 50 cents rather than 2 dollars for each pencil in the first pack.
Answer:
the domain is all real numbers except x=3
Step-by-step explanation:
The domain is the values that x can take
X can be all real number except when the denominators equal zero
x-3 ≠ 0
x≠3
the domain is all real numbers except 3
