Ivahew [28]3 years ago
4 0

Answer:

X=3

Step-by-step explanation:

Equation 1:

7×3=21

21+18=39

Equation 2:

10×3=30

30+9=39

If you replace x with 3 on both equations then you get 39 and if you get 39 on both equations that means it is equal.

A person is purchasing a new golf club bag. The compartment for the golf balls is approximately the shape of a rectangular prism
Lerok [7]

Answer:

The answer to your question is: ≈ 178 balls

Step-by-step explanation:

Data

rectangular prism = 8 in x 11 in x 5 in

golf balls = 1.68 in diameter

Formula

Volume rectangular prism = l x w x h = 8 x 11 x 5 = 440 in³

Volume of ball = (4/3) πr³ = (4/3) (3.1416) (0.84)³ = 2.48 in³

# of balls inside the compartment = volume rectangular prism / volume ball

# of balls = 440 / 2.48

               = 177.4 ≈ 178 balls

PUT THESE NUMBERS IN ORDER GREATEST TO LEAST ✔✔ I WILL ADD BRAINLIST
Fiesta28 [93]

Answer:

2 12/16, 2 18/25, and lastly 2.

Step-by-step explanation:

Since 2 is least, we can put that at the end. That leaves us with 2 18/25 and 2 12/16. Since 12/16 is greater, we will put that as the greatest. 2 18/25 is in the middle. Hope this helps!
