Which expression modeled by the array?

a: 2 * 6 + 4
b: 3 * 5 + 1
c: 4 * 2 + 8
d: 5 * 2 + 6

Answer is a because first 2 lines are 6

so 2*6
bottom line is 4

2*6+4 is answer

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
