Bill can hit a bucket of 323 gold balls in 17 hours.
yanalaym [24]
It is important to clearly understand all the important information's already given in the question. Based on those details the answer to the question can be easily determined.
In 17 hours the number of golf balls hit by Bill = 323
Then
In 1 hour the number of golf balls hit by Bill = (323/17) * 1
                                                                     = 19
So
The number of golf balls hit by Bill in 23 hours = 23 * 19
                                                                          = 437
So 437 balls will be hit by Bill in 23 hours. I hope the procedure is clear enough for you to understand. This procedure will help you to solve similar problems in future without requiring any outside help.

How is the answer 35? How do I get it?
vlabodo [156]
I think it's -35. The steps to get that number is subtracting the 3 to the right side. Then you have -2 - 3 which equals to -5. Then you still have x/7= -5. Get rid of 7 from the x and do the same thing to the other side but you multiply 7 and -5. Last you your would be x= -35.

What is the length of cloth needed to make 24 shirts if each shirt is made from .75 yards of material?
RideAnS [48]

Answer:

18 yards of material needed to make 24 shirts

Step-by-step explanation:

The unit rate is

        1 shirt

------------------------------ = 1 1/3 shirts per yard of material = 4/3 shirt/yard

 0.75 yards material

This rate could also be written as 3/4 yard per shirt

Multiply this latter rate by 24 shirts:

 3 yard

-------------- * 24 shirts = 18 yards of material needed to make 24 shirts

 4 shirt
