Answer:

5x + 32 < 50

Step-by-step explanation:

On a particular airline, bags checked in must weigh less than 50 pounds. Betty packed 32 pounds of clothes and five gifts that weigh the same amount.

If each gift weighs w pounds, then the weight of five gifts will be 5w pounds and an additional 32 pounds of clothes will make it total (32 + 5w) pounds.

scZoUnD [109]
The property of real numbers illustrated by the equation 16(3t+4v)=48t+ 64v.

 Therefore, the answer is: Distributive property.

 As you can see, you have the equation 16(3t+4v), and when you apply the Distributive property, you obtain:

 16(3t+4v)
 (16)(3t)+(16)(4v)
 48t+64v

Help me solve this please an explain it to me
sertanlavr [38]
You need to use the order of operations to solve this, which is PEDMAS; however, there is no real order of if division should come before multiplication or vice versa, so you do it in the order it appears in the problem. This is true for addition and subtraction as well.

-8 / -2 = 4

4 • 6 = 24

5+24 = 29

Your answer is 29
