THE RATIO OF ZOE’S MONEY TO PERRY’S MONEY WAS 2:3. AFTER PERRY GAVE ½ OF HIS MONEY TO ZOE, ZOE HAD $210. HOW MUCH MONEY DID ZOE HAVE TO START?

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:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

your answer is c. y = [x] + 1

a.

step-by-step explanation:

a constant is a number without a variable, and m will always have a variable, therefore making m a constant. a term is just a part of an equation, so that makes any part of an equation always a term, so the answer will not be term.
