are girls with blond hair.
b. Of all the students, are boys without brown hair.
Step-by-step explanation:
a. You know that 
of the students are girls (This means that 
of the studes are boys) and 
of these girls have blond hair.
Then, of is:
Therefore, of all the students, are girls with blond hair.
b. You know that 
of the boys have brown hair.
Then, of is:
Of all the students, are boys without brown hair.
Answer:
50 inches
Step-by-step explanation:
Hi there!
where l is the length of the rectangle and w is the width of the rectangle
Plug in the length (15 inches) and width (10 inches)
Therefore, the perimeter of the frame is 50 inches.
I hope this helps!
P is (18, -16)
to find the answer, u would solve it in reverse order of the midpoint formula by first doing the x-values:
5(2)= 10-(-8) = 18
and then the same to y-values:
-10(2)= (-20)-(-4) = -16
to get:
(18, -16)
Right this is pretty simple all you do is sub the points to the equation given.
So first try the first point (2,-1) in y=-3x+7
==> -1=-3(2)+7
==>-1=1 this is not equal therefore not the right points
Then try (1,10)
==>10=-3(1)+7
==>10=4 this is incorrect therefore not the right points
Next try (3,-2)
==>-2=-3(3)+7
==>-2=-2 this is equal therefore this is the coordinates to the linear equation.
Finally try the last points to make sure you are correct.
==> -8=-3(-5)+7
==>-8=22 this is incorrect also.
Therefore the only coordinates that satisfies the equation is (3,-2)
