Nevaeh went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 400 mg of sodium and each frozen dinner has 600 mg of sodium. Nevaeh purchased a total of 7 cans of soup and frozen dinners which collectively contain 3600 mg of sodium. Graphically solve a system of equations in order to determine the number of cans of soup purchased, x, x, and the number of frozen dinners purchased, yy.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

central angle of a triangle has the same measure as its intercepted arc.
