Answer:
B. DC = 29 and DE = 44.5
Step-by-step explanation:
I honestly don't know how to get DE but because DC has to be 29, the second option is the only right answer

To solve x:
1. Substract 19 in both sides of the equation:

2. Multiply both sides of the ewuation by 10/9:

<h2>Then, the value of x is 60 (x=60)</h2>
Answer:
<em>X ball bearings will be made in 1 hour and 20 minutes</em>
Step-by-step explanation:
<u>Proportions
</u>
The proportions give us an important tool to easily solve common problems of any type. We know that:
Company ABC can make X ball bearings in 3 hours.
Company DEF can make X ball bearings in 4 hours.
Company GHI can make X ball bearings in 6 hours.
In one hour, each company can make
ABC: X/3 ball bearings
DEF: X/4 ball bearings
GHI: X/6 ball bearings
Working together, they can make
ball bearings. Operating
If they can make 3/4 of a ball bearing in one hour, then one complete ball bearing will need
hours to complete. It's equivalent to 1 1/3 hours or 1 hour and 20 minutes
X ball bearings will be made in 1 hour and 20 minutes
That should be your answer
It would be irrational, there is a math calculator called math papa if you need to check your answer
