Answer:

Step-by-step explanation:

<u>1.Find the LCM(Least Common Multiple).</u>
That would be 20.
<u>2.Multiply so all denominators are equal.</u>

<u>3. Add</u>
<u></u>
<u>4. Simplify</u>
<u></u>
Leannie bought 5 of Dr. Mumin’s book and 3 of Dan Moyer’s book
For the first problem the answer is -5/2
2x−7+10=−2
Step 1: Simplify both sides of the equation.
2x−7+10=−2
2x+−7+10=−2
(2x)+(−7+10)=−2
(Combine Like Terms)
2x+3=−2
Step 2: Subtract 3 from both sides.
2x+3−3=−2−3
2x=−5
Step 3: Divide both sides by 2.
2x/2=−5/2
x=−5/2
Answer:
x= -5/2
X=25 and y=-2 so then y=-40 and x=? you will have to divide and and multiple and the answer will be x=500
The average of those five amounts is 183,636.7
AVeraging is adding all of the numbers together with the dividing by a number of numbers you have.
