If 60% out of the 2,660 students are males, then
40% out of t<span>he same 2,660 students are females
Ten the number of females is 40% x 2660 = 0.4 x 2660 = 1,064 females</span>
Answer:
(x+11)(x-2)
Step-by-step explanation:
To factorise: x^2+9x-22
You must first divide the centre term in such a way that the sum of the 2 values will be divisible by x squared and minus 22 respectively.
So x^2+9x-22 = x^2 -2x + 11x - 22.
Now factorize x^2 - 2x and 11x-22 individually.
x^2 - 2x = x(x-2)
11x - 22 = 11(x-2)
Since these both have the same value in the brackets, use 5at one of the brackets and the other is the combination of them together:
(x+11)(x-2)

Answer:
110 and 70
Step-by-step explanation:
opposite sides of parallelograms are equal so you can set 2x+30 equal to 5x-90
when you do this:
2x+30=5x-90
-2x -2x
30=3x-90
+90 +90
120=3x
/3 /3
40=x
now you can plug 40 in for 5x-90
example:
5(40)-90
200-90
110
m<r=110
<r and <s are supplementary because they are consecutive angles
supplementary is when two angles add up to 180
since <r is 110, do 180-110 and get 70
m<s = 70
