Respuesta :
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)
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!!
