Question

Does anyone know the answer to these questions? 2/3(9m-6)=20 -5(2k-1)=17-2k 0.4(5+2x)-0.5=3(0.3x+7)

Answer 1

(2/3)(9m - 6) = 20

9m - 6 = 30

9m = 36

m = 4

-5(2k - 1) = 17 - 2k

-10k + 5 = 17 - 2k

-12k = 12

k = -1

0.4(5 + 2x) - 0.5 = 3(0.3x + 7)

2 + 0.8x - 0.5 = 0.9x + 21

0.8x + 1.5 = 0.9x + 21

0.1x = -19.5

x = -195
