Question

5. Solve each equation.
​

Answer 1

Answer:

A. - 35= - 0.51

= - 0.51 + 35

= 34.49

B. 2/5 k = -2

=>k = -2 -2/5

=>k = -10-2/5

=>k = -12/5

C. 25 - r = 30

=> -r = 30 -25

=> -r = 5

=> r = 5

Answer 2

Answer:

A. f = 70

B. k = -5

C. r = -5

Step-by-step explanation:

A. -35 = -0.5f

-35 ÷ - 0.5 = f

70 = f

B. (2/5)k = -2

k = -2 ÷ 2/5

k = -2 × 5/2

k = -5

C. 25 - r = 30

25 - 30 = r

-5 = r
