There are three baby giraffes at the zoo. one weighs 148 pounds one weighs 125 pounds and the other weighs 137 pounds. what is the combined weight

The combined weight is 410 pounds

Step-by-step explanation:

* Lets explain how to solve the question

- There are three baby giraffes at the zoo

- One weighs 148 pounds

- One weighs 125 pounds

- The other weighs 137 pounds

- We want to find the combined weight

∵ Combined weight means the sum of their weight

∴ The sum of their weight is the sum of 148 , 125 and 137

- We can find this sum by easy way if we do that:

∵ 148 = 100 + 40 + 8

∵ 125 = 100 + 20 + 5

∵ 137 =  100 + 30 + 7

         = 300 + 90 + 20

∵ 300 + 90 + 20 = 410

∴ 148 + 125 + 137 = 410

∴ The combined weight is 410 pounds

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
