Acell phone company offers you a plan that charges a flat rate of $25 per month for 200 minutes of airtime. the rate of any time in excess of 200 minutes is $.12 per minute.

a. write an expression for the monthly dollar amount spent for the cell phone service if you want to use x minutes of airtime in excess of 200 minutes.

b. write an equation which indicates that you have budgeted no more than $40 per month to spend on the service.

c. determine the maximum number of minutes you can use in excess of 200 minutes so that you do not exceed your $40 per month budget.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
