Question

Given: x + a = b

If x = 4.907 and b = 13.089, what is the value of a?
A) 7.781
B) 8.182
C) 9.812
D) 17.996

Answer 1

Answer:

B) 8.182

Step-by-step explanation:

x + a = b

We know  x = 4.907 and b = 13.089.  Substitute these values into the equation

4.907 +a = 13.089

Subtract 4.907 from each side

4.907 - 4.907 +a = 13.089-4.907

a =8.182
