Solve the equation: -4 (8+y) = 90

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle

Divide. –4.2 ÷ 6 = a –0.7 b 0.7 c –7 d 7 me
