Answer:

M=-2

Step-by-step explanation:

3m+2−1/4m=1/2(m−5)

Step 1: Simplify both sides of the equation.

3m+2−1/4m=1/2(m−5)

3m+2+−1/4m=(1/2)(m)+(1/2)(−5)(Distribute)

3m+2+−1/4m=1/2m+−5/2

(3m+−1/4m)+(2)=1/2m+−5/2

(Combine Like Terms)

11/4m+2=1/2m+−5/2

11/4m+2=1/2m+−5/2

Step 2: Subtract 1/2m from both sides.

11/4m+2−1/2m=1/2m+-5/2−1/2m

9/4m+2=−5/2

Step 3: Subtract 2 from both sides.

9/4m+2−2=−5/2−2

9/4m=−9/2

Step 4: Multiply both sides by 4/9.

(4/9)*(9/4m)=(4/9)*(−9/2)

m=−2

Answer:

m=−2

I need help with this, it's due in 15 mins-
LiRa [457]

Answer:

Mean: 3.5263157894737

Median: 3

Mode: 3

Step-by-step explanation: The mode is 3 because the mode is for which number pops up the most, which is 3.

I got the median by crossing out 8 from the left and the right of the number set and got 3 as the last number.

I got the mean by adding up all the numbers and divided it by the amount of numbers in the set.

the length of a rectangular sign is 5 times its width. If the sign's perimeter is 24inches, what is the signs area
anastassius [24]

Answer:

20 square inches

Step-by-step explanation:

Set width of sign to x.

Set length of sign to y.

5x=y

2(x+y)=24 inches

2(x+5x)=24 inches

12x=24 inches

width = 2 inches

length = 10 inches

Area = 20 square inches

3a² + 11a – 42<br><br>this is factoring in algebra 2 (high school) <br>​
N76 [4]

To factor,

<h2>[[[</h2>

1) First multiply coefficient of a² and constant no,

That is,

3×(-42)=-126

Since the<u> resultant no is negative</u>, you should find two such factors of 126 <u>which</u> <u>will give us the coefficient of a (=11)</u> on subracting those factors.

2) Find the factor

126=2×3×3×7

=18×7

18 and 17 are factors of 126

Also,18-7 =11.

So they are required factors for factoring,

<h2>]]]</h2>

Once you have understood above steps you can solve on your own. All you need to do is split 11 into factors ,take common terms and you will get answer.

<u>Answer:</u>

3a²+11a-42

=3a²+(18-7)a -42

=3a²+18a-7a-42

=3a(a+6) -7(a+6)

=(a+6)(3a-7)
