Question

9)Solve e/4 – 10 = -20 (CHECK on your graph paper.)
10) Solve 0.4k – 4 + 1.6k = 14 (CHECK on your graph paper.)

Answer 1

Answer:

9) e=-40 10) k=9

Step-by-step explanation:

9) e/4-10=-20  add 10 on both sides

e/4=-10  Multiply everything by 4

e=-40

10) 0.4k-4+1.6k=14   combine like terms

2k-4=14   Add 4 on both sides

2k=18   divide both sides by 2

k=9
