The total mass of vitamin C in one apple and two peaches is 17 mg. The total mass of vitamin C in two apples and one peach is 13 mg. What is the mass of vitamin C in an apple and the mass of vitamin C in a pear?

The mass, in milligrams, of vitamin C in an apple is:

The mass, in milligrams, of vitamin C in a pear is:

3 and 7 respectively

Step-by-step explanation:

Let the mass, in milligrams, of vitamin C in an apple be x

Let the mass, in milligrams, of vitamin C in a pear is be y

x+2y=17

2x+y=13

Solving for x and y, we get x=3 and y=7

add an image, and i will answer

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
