We can write a proportion for this question
5 out of 32 students and we have to find how many (x) out of 800
5/32 = x /800
cross multiply
5*800 = 32x
4000 = 32x
divide both sides by 32
125 = x
About 125 students of the 800 ride their bikes to school.
Hope this helps :)

Answer: x=6
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
Step-by-step explanation:
We know that on both 10 & 12 the angles add up to equal 90° so...
10. 8x+7x=90
15x=90
x=6
12. it's the same in pic as 10
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
That is false. The parabola opens to the right.
I'm pretty sure its −1 7/8
