Answer:
<em>The answer is 200</em>
Step-by-step explanation:
<em>To solve the question given, let us recall the following,</em>
<em>Let r4=200 miles apart</em>
<em>r=50 mph combined speed
</em>
<em>Where </em>
<em>2f+10=50
</em>
<em>2f=40
</em>
<em>f=20
</em>
<em>f+10=30
</em>
<em>or we can express it in another way,</em>
<em>which is</em>
<em>f x4+(f+10)x 4=200
</em>
<em>f x4+f x4+40=200
</em>
<em>8f+40=200</em>
<em>Then</em>
<em>8f is =160
</em>
<em>f=20
</em>
<em>f+10=30
</em>
<em>Therefore,</em>
<em>4x 20+4 x 30=200
</em>
<em>80+120=200
</em>
<em>200=200</em>

Answer: a) No Solution
b) Infinite Solutions (All Real Numbers)
<u>Step-by-step explanation:</u>
4(g + 8) = 7 + 4g
4g + 32 = 7 + 4g <em>distributed 4 into g + 8</em>
32 = 7 <em> subtracted 4g from both sides</em>
Since the statement is false because 32 ≠ 7, then there is NO SOLUTION
-4(-5h - 4) = 2(10h + 8)
20h + 16 = 20h + 16 <em>distributed</em>
16 = 16 <em>subtracted 20h from both sides</em>
Since the statement is true because 16 = 16, then there are INFINITE SOLUTIONS so x can be all real numbers.
Answer:
Add the numbers together and divide by the number of numbers. (The sum of values divided by the number of values). Arrange the numbers in order, find the middle number. (The middle value when the values are ranked).
Factor by grouping.

Answer:
The width of the rectangle is 14'8", and the length is 33'4"
Step-by-step explanation:
We're given two pieces of information:
The length is eight more than twice the width:
The perimeter is 96 feet:
We also need to apply one more piece of information that is not provided here, and that is the relationship between the perimeter of a rectangle, and it's length and width:
We can solve for w by plugging the other two values into the last:
Now we can find the length by plugging w into the first equation:
One third of a foot is four inches, so the width is 14'8" and the length is 33'4"
To make sure our answer is correct, we should plug those numbers back into the area equation and see if we're right:
So we know our answer's correct
