Answer:

Well the answer is 57.

Step-by-step explanation:

Okay think about it 10+10 is 20 how do you know this well 1+1=2 and add a zero. So in 10+47 4+1=5 and keep the 7 because the other number is a zero which has no affect on the number unless both numbers are zero.

1. Evaluate the expression -6.3a +2(a - b) for a = -2 and b = 1.1.
sasho [114]

Answer:

D or 6.4

Step-by-step explanation:

-6.3*(-2) + 2(-2 - 1.1)

- 6.3 * - 2 = 12.6 Notice that the two minus signs become a +

(-2 - 1.1)= (-3.1)   Multiply -3.1 * 2 = - 6.2

12.6 - 6.2 = 6.4
