Given:
A number is q, multiply it by 2 and add 5.
You get the same answer as when you minus 2 from q.
To find:
The value of q.
Solution:
The algebraic representation of the statement "a number is q, multiply it by 2 and add 5" is
Multiply q by 2 = 2q
Multiply q by 2 and then add 5 : 2q + 5
So, the first result is 2q+5.
When you minus 2 from q = q-2
So, the second result is q-2.
According to the question, both results are equal. Equate both results to get the value of q.
[tex]2q+5=q-2[/tex]
Isolate variable terms.
[tex]2q-q=-5-2[/tex]
[tex]q=-7[/tex]
Therefore, the value of q is -7.

An isotope of iodine has a mass of 134 amu. How many neutrons does the
isotope contain?
A. 67
B.153
C. 81
D. 74
Answer:
The correct option is C: the isotope of iodine contains 81 neutrons.
Step-by-step explanation:
The mass (A) of the iodine isotope is given by:
[tex]A = Z + N[/tex]
Where:
Z: is the number of protons
N: is the number of neutrons
For iodine Z= 53, so if A = 134 the number of neutrons is:
[tex] N = A - Z = 134 - 53 = 81 [/tex]
Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.
I hope it helps you!

Jasmine and Scott want to chart their reading rates to see how much they improve each quarter. Below are the results of their first quarter tests. Write their results as unit rates. Jasmine can read 120 words per minute. 2. It takes Scott one minute to read 130 words.
Answer:
a) 120 words per minute
b) 130 words per minute
Step-by-step explanation:
A unit rate (also called a single-unit rate) is a type of ratio that compares 1 unit of one quantity to a different number of units of a another different quantity. When expressing in unit rate, the second quantity is in one unit.
a) Jasmine can read 120 words per minute
Jasmine reading unit rate = total number of words read / time taken
Jasmine reading unit rate = 120 words / 1 minute = 120 words per minute
b) It takes Scott one minute to read 130 words
Scott reading unit rate = total number of words read / time taken
Scott reading unit rate = 130 words / 1 minute = 130 words per minute

Harley was eating pizza and had already eaten six pieces before his sister, Samantha, got home. Samantha was worried that she was not going to get a fair share of the pizza and wanted to know how many pieces were in the pizza originally. Harley told her, "I have only eaten 3/8 of the pizza. How many slices where in the pizza when it was whole
Answer:
16 pieces of pizza when the pizza was whole.
Step-by-step explanation:
You know that 6 pieces are equal to 3/8 of the pizza.
Let x represent the total number of pieces and write an equation:
3
-- times x = 6
8
Multiply each side of the equation by 8:
8 times 3
-- x = 8 times 6
8
3x = 48
Divide each side of the equation by 3:
3x 48

I cant get an accurate answer for this problem Help!
Answer:
No solutions
Step-by-step explanation:
3(2y + 4) = 7y + 4 - y
~Simplify both sides
6y + 12 = 6y + 4
~Subtract 12 to both sides
6y = 6y - 8
~Subtract 6y to both sides
0 = 8

In 25 minutes Jezebel can run 10 laps around the track. Part I) Determine the unit rate for the number of laps she can run per minute. Part II) Find the constant of proportionality for this situation.
Answer: See explanation
Step-by-step explanation:
a. Determine the unit rate for the number of laps she can run per minute.
This will be calculated as the number of minutes used divided by the number of laps which will be:
= 25 / 10
= 2.5 minutes per lap.
b. Find the constant of proportionality for this situation.
We will use the formula y = kx
where y = 25, x = 10, k = constant of proportionality.
Therefore, y = kx
25 = 10k
k = 25/10
k = 2.5
The constant of proportionality is 2.5
Which is the graph of the linear inequality x – 2y > –6?
Answer:
uhhh d????
Step-by-step explanation:
Graph D represents the linear inequality x – 2y > –6.
The given inequality is x – 2y > –6.
We rearrange the inequality as y < (1/2)x + 3
Now we have the inequality in slope-intercept form, y < mx + b, where m is the slope (1/2) and b is the y-intercept (3).
To graph this inequality, you can start by plotting the y-intercept, which is the point (0, 3).
The slope of the graph is 1/2.
However, the inequality is y < (1/2)x + 3, which means the shaded region is below the line.
Hence, graph D represents the linear inequality x – 2y > –6.

Find DE
13x-37
2x+13
Answer:
DE = 27
Step-by-step explanation:
From the picture attached,
Points D and E are the midpoints of the segments AC and BC and DE is the mid-segment joining these points.
By the mid-segment theorem,
A segment joining midpoints of the two sides of a triangle is parallel to the third side. length of mid-segment is half of the 3rd side in measure.
DC = [tex]\frac{1}{2}\text{AB}[/tex]
(2x + 13) = [tex]\frac{1}{2}(13x-37)[/tex]
2(2x + 13) = (13x - 37)
4x + 26 = 13x - 37
13x - 4x = 26 + 37
9x = 63
x = 7
DE = 2x + 13
= 2(7) + 13
= 14 + 13
= 27
