There are 39 fewer 2nd graders than 3rd graders there a 67 2nd graders how many 3rd graders are thereThere are 39 fewer 2nd graders than 3rd graders there a 67 2nd graders how many 3rd graders are there​

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
