3(2m+12) -4m = 20 -3(3m+5)
Step 1. Distribute 3 to (2m+12) and -3 to (3m+5)
Distribution property:
When you are distributing, you multiply the outside number by the numbers inside. For example,
-1(4-2)
-1 times 4, -1 times -2
-4, 2 (negative times negative =positive)
Then you would get
-4+2. You do not distribute with multiplication and division. So then we would do this with our numbers.
6m+36 -4m = 20 -9m-15
______
Step 2. Simplify by adding like terms.
Like terms:
Terms are separated by operation symbols (+,-,*,➗). Like terms are terms with the same variable next to it. 5a and 6a are like terms. Terms with no variables at all are also like terms. 5 and 6 are like terms. 8a and 7 are not like terms. 9a and 9b are not like terms.
6m+-4m= 2m. 20+(-15)=5
_____
2m+36=5-9m
Step 3. Add 9m to both sides
11m+36=5
____
Step 4. Subtract 36 from both sides
11m=-31
____
Step 5. Divide by 11
m=-31/11
If you can please provide brainliest. I took 30 minutes doing this.
Solution:
<u>A few definitions...</u>
- Rational number - Any integer, fraction, terminating decimal, or repeating decimal is classified as a rational number
- Irrational number - All the real numbers which are not rational numbers.
<u>Option A - Rational or Irrational?</u>
Since both are known as fractions, they are rational numbers.
<u>Option B - Rational or Irrational?</u>
√2 is classified as an Irrational number because if it is simplified, it does not result in any integer, fraction, terminating decimal, or repeating decimal.
<u>Option C - Rational or Irrational?</u>
- 1/√4 + 7/2
- => 1/2 + 7/2
- => 8/2 = 4
Since this is an integer, this is rational.
<u>Option D - Rational or Irrational?</u>
- √9 + √4
- => √3 x 3 + √2 x 2
- => 3 + 2 = 5
Since this is an integer, this is rational.
In conclusion...
Option B is correct.

Answer:
multiplication
Step-by-step explanation:
In math, "X of Y" means that X is multiplied by Y*. Here, you need to figure out what values are being multiplied.
The fraction of claims remaining unpaid after the first month is ...
1 - 4/7 = 7/7 -4/7 = 3/7 . . . . fraction of claims unpaid after month 1
The problem statement tells you 2/3 of these are paid in the second month. That is ...
(2/3) × (3/7) = 2/7 . . . . of the total of all claims
2/7 of all claims were paid in the second month.
_____
* The interpretation of the word "of" will depend on the context. Here, we're referring to X being a percentage or fraction, as in "2/3 of 3/7".
In some uses, the word "of" may signify that X is multiplied by a fraction with Y as the denominator, as in "5 of 8" (meaning 5/8), for example. If Y is an object, the X is still a multiplier, as in "3 of the bags of cement".
