how do you solve twelve less than the quotient of a number and 7 is -2
Answers
Remark
One of the things you need to do is learn to read phrase by phrase.
What is the quotient of a number and 7? That meas you have a number, x, and it is divided by 7. What you do that the answer you get is the quotient.
x/7 is what you know so for. Now the first part says you take 12 away from that.
x/7 - 12 is what you have after doing that.
The result you get is - 2
x/7 - 12 = - 2 Add 12 to both sides
x/7 - 12 + 12 = - 2 + 12
x/7 = 10 Now multiply by 7
x = 10 *7
x = 70 <<< Answer the number is 70

LM=7, LN=10, MN=5, What can you conclude about the angle measures
Answers
.. ∠L ≈ 27.66°
.. ∠M ≈ 111.80°
.. ∠N ≈ 40.54°
The smallest angle will be opposite the shortest side; the largest angle will be opposite the longest side.
Given the lengths stated, we conclude that triangle LNM is a right triangle. Angle LNM would be the right angle, and angles NML and NLM can be calculated with trigonometry if necessary.
Explanation:Given the lengths of triangle LNM with LM = 7, LN = 10, and MN = 5, we can infer that this triangle is a right triangle. This is concluded through the use of the Pythagorean theorem, which defines that in any right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. Specifically, in this case, we can observe that 10² (LN) equals to 7² (LM) + 5² (MN), because 100 equals 49 + 25. Consequently, since LN is the hypotenuse, angle LNM is the right angle, and angles NML and NLM can be found using trigonometric functions if needed.

Laura’s cell phone service costs $65 per month, plus an additional $0.10 per text message sent. The table below shows the cost for Zach’s cell phone service based on the number of texts messages he sends. How much cheaper is Zach’s cell phone service than Laura’s when no text messages are sent?
Answers
When no text messages are sent, Zach's cell phone service is $55 cheaper than Laura's each month.
Explanation:Laura's cell phone service costs $65 per month regardless of how many text messages she sends. On the other hand, Zach's cell phone service cost is represented by the variable equation $10 = $2× QRT + $.05 × QPC. However, since no text messages are sent in this scenario, the number of text messages (QPC) is 0. Therefore, all the terms in the equation that involve QPC becomes zero. Hence, Zach's cell phone service costs $10 per month when no text messages are sent. So if we compare Laura's cell phone costs to Zach's without sending any text messages, Zach is paying $65 - $10 = $55 less than Laura each month.

Step-by-step explanation:
All you would have to do is multiply all the numbers together and then choose your answer
Rebecca needs 4,464 square inches of wrapping paper to completely cover the boxes.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Each box has six sides, and the dimensions of each side are:
12 x 10, 12 x 10, 12 x 3, 12 x 3, 10 x 3, and 10 x 3 inches.
The total surface area of each box is:
2(12 x 10) + 2(12 x 3) + 2(10 x 3) = 240 + 72 + 60
= 372 square inches.
Since there are 12 boxes, the total surface area of all the boxes is:
= 12 x 372
= 4,464 square inches.

Samantha works at a nursery where she pots plants. It takes her 1 1/2 hours to pot 12 plants. How many plants can Samantha pot in hour?
Answers
Samantha can pot 8 plants in one hour.
To calculate how many plants Samantha can pot in one hour, we need to determine the rate at which she pots plants. She currently pots 12 plants in 1 1/2 hours, which is equal to 1.5 hours.
To find the rate, we divide the number of plants by the number of hours:
12 plants /1.5 hours=8 plants per hour
Therefore, Samantha can pot 8 plants in one hour.
Gloria Trench checked her gas mileage and found that she had used 16.6 gal of gas to travel 372 mi. At this rate, how many gallons will she use to travel from San Francisco to Washington, D.C., a distance of 2,850?
Answers
Using the rate of miles per gallon for Gloria's car, we calculated that she will need approximately 127.2 gallons of gas to travel from San Francisco to Washington, D.C.
Explanation:To solve this problem, we'll use the principle of ratios.
First, we find the rate of miles per gallon for Gloria's car by dividing the distance travelled by the gallons used:
372 miles ÷ 16.6 gallons = 22.4 miles per gallon
With this information, we can calculate how many gallons Gloria will need to travel from San Francisco to Washington D.C., which is a distance of 2850 miles:
2850 miles ÷ 22.4 miles per gallon = 127.2 gallons
So, Gloria will use approximately 127.2 gallons of gas to travel from San Francisco to Washington, D.C., at her current rate.

What is the 32nd term of the arithmetic sequence where a1 = −33 and a9 = −121? −396 −385 −374 −363
Answers
The formula to find the general term of an arithmetic sequence is,
[tex] a_{n} =a_{1} +(n-1)d [/tex]
Where [tex] a_{n} [/tex]= nth term and
[tex] a_{1} [/tex] = First term.
Given, a9 = −121. Therefore, we can set up an equation as following:
[tex] -33+(9-1)d = -121 [/tex] Since, a1 = -33
- 33 + 8d = -121
-33 + 8d + 33 = -121 + 33 Add 33 to each sides of the equation.
8d = -88.
[tex] \frac{8d}{8} =\frac{-88}{8} [/tex] Divide each sides by 8.
So, d = - 11.
Now to find the 32nd terms, plug in n = 32, a1 = -33 and d = -11 in the above formula. So,
[tex] a_{32} = -33 +(32 -1) (-11) [/tex]
= -33 + 31 ( -11)
= - 33 - 341
= -374
So, 32nd term = - 374.

So, we have 2185 student in Rose.
Lily School has 307 more students than Rose, so Lily has,
2185 + 307 = 2492 Students in Lily School.
Since question a. is asking you to round off to the nearest ten, your answer to part a is 2490.
For part b. add 2185 and 2490.
2185 + 2490 = 4675 students.
The questions want you to round to the nearest hundredth, so,
4700 is the answer to part b.
For simplicity, let L and R represent the numbers of students in Lily school and Rose school, respectively. The first sentence tells you
.. R = 2185
The second sentence tells you
.. R = L - 307
a) This question asks you the value of L. Use the given information to find it.
.. 2185 = L -307
.. 2185 +307 = L
.. 2492 = L
You are asked to round this number to the nearest 10. This means you look at the 1s digit (2) and decide if it is 5 or more (it is not). If it is, you add 1 to the tens digit (here, you don't) and then report the number with the 1s digit made zero:
.. There are 2490 pupils in Lily school.
b) This question asks you the total number in both schools. That will be
.. L +R = 2492 +2185 = 4677
You are asked to round this number to the nearest 100. This means you look at the 10s digit (7) and decide if it is 5 or more (it is). If it is, you add 1 to the hundreds digit (here, you do) and then report the number with the 10s and 1s digits made zero:
.. There are 4700 pupils total in the two schools.
