Help (with right answer) I will cash app you 5

9) 25

10) 100

Step-by-step explanation:

9)

if the total class is 5x, and the people who wear glasses is 2x,

that means that the people who do not wear glasses would be 3x

(because 5x - 2x = 3x)

the problem tells us that there are 15 people who do not wear glasses.

15 = 3x

15/3 = 3x/3

15/3 = x

5 = x

since x is 5, the total number of students is 25

because 5 * 5 = 25

10)

to start, divide 250 by 50.

250/50 = 5

250 is 5 times greater than 50.

since the ratio of dollar to game point is proportional,

you just need to multiply 5 by 20$ to get the answer

5 * 20 = 100$

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
