Determina cuáles de las siguientes expresiones son ecuaciones y cuales no Justifica, tu respuesta.

a. 40 + x = 15

b. 27 + 40 + 16 = 83

C. P -89 = 46

d. {[3 + 2 + (9-7) 4 (3+ 4)}}

e. m + 25 + 32 91

f. 32 +251 - 361-55

g. y - 3 = -7

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

i think it would be c
