(5x + 10) + 55 = 90

5x + 10 + 55 = 90

5x + 65 = 90

5x + 65 - 65 = 90 - 65 (the 65 crosses off)

A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother. Which equation expresses the weight of the mother? * n – 1,400 = 7,437 n + 1,400 = 7,437 n x 7,437 = 1,400 n + 7,437 = 1,400

Answers

Answer:

n – 1,400 = 7,437

Step-by-step explanation:

A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.

Let us represent :

Weight of the mother elephant = x

Weight of the baby elephant = y

A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.

y = x - 7437 pounds

Hence,

1400 pounds = x - 7437 pounds

The weight of the mother elephant =

x = 1400 pounds + 7437 pounds

Therefore, the equation that expresses the weight of the mother where, the weight of the mother = n is:

n – 1,400 = 7,437
