Question

Select all the equations where d=4 is a solution

Answer 1

A) 2d + 3 = 11 → 2d = 8 → d = 4, this is right

B) 11d + 15 → this is an expression, so no

C) 5d + 7 = 27 → 5d = 20 → d = 4, this is right

D) 9 + 2d = 16 → 2d = 7 → d = 3.5, this isn't right

E) 3d = 7 → d = 2.3, this isn't right

That means the answers are A and C

Hope this helps!!

Answer 2

A. 2 • 4 = 8 + 3 = 11 (select)

B. 11 • 4 = 44 +15 = 59 (select only if the solution is 59; the answer was not included)

C. 5 • 4 = 20 + 7 = 27 (select)

D. 2 • 4 = 8 + 9 = 17 (do not select)

E. 3 • 4 = 12 (do not select)
