kiruha [24]

Answer:

C. a = 7

D. c = -3

Step-by-step explanation:

C. 7(2a + 3) + 21 = 100+ 40

     -12c = 56 - 20

     -12c = 36

       c = - 3

Percent error is the difference between the measured and known value, which is divided by the known value, and then multiplied by 100%.

Percent error = (Estimated number- Actual number)/Actual Number × 100.

= 18/42 × 100

= 0.429 × 100
