show your work : 17-8n=-2(4n-7)-3
Answer:
i think so
Step-by-step explanation:
17‒8n=‒2(4n‒7)‒3
17‒8n=‒8n+14‒3(add ‒17 on both sides)
‒8n=‒8n+14‒3‒17
‒8n=‒8n‒6
‒8n+8n=‒6
0=‒6
so the equation doesn't have solution
find measure of angle a.
find measure of 1 interior angle in the regular polygon
find measure of angle
Answer:
150
Step-by-step explanation:
First a diagram which looks like a 12 sided figure where all the sides are equal.
Now draw 2 consecutive radii.
There are 12 such triangles in a 12 sided polygon.
These triangles have an apex angle of 360 / 12 = 30 degrees.
The other two angles making up the triangle are both equal. Therefore x + x + 30 = 180
2x = 150
x = 75
But 75 is 1/2 of the interior angle. There are 2 such angles making up the interior angle 75 + 75 = 150

Three times the sum of 2 and e
Answer:
6 + 3e
Step-by-step explanation:
The expression in the mathematical form will be 6 + 3e.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Three times the sum of 2 and e. Then the expression in the mathematical form will be
The sum of 2 and e will be
⇒ 2 + e
Then the three times the sum of 2 and e will be
⇒ 3(2 + e)
⇒ 6 + 3e
The expression in the mathematical form will be 6 + 3e.

Two thirds a number x plus 6 is 9
Answer:
please mark brainliest!
Step-by-step explanation:
[tex]\frac{2}{3}x + 6 = 9[/tex]
2/3 of x is (2/3x)
6 added to that makes it (2/3 +6).
Saying this is 9 means it is equal to 9.
2/3x +6 = 9
Answer:
2/3x+6=9

Kip walks 5/9 mile in 5/8 hour. What is kips rate of speed? How far can kip walk in one hour?
Step-by-step explanation:
5/8 hr = 5/9 mile
1 hr = 5/9 ÷ 5/8
= 8/9 mile
Speed = distance / time
= 5/9 mile / 5/8 hr
= 8/9 miles per hr?

Mr. Wagner is on a diet. He currently weighs 250 pounds. He loses 3 pounds per month. Write an equation that represents his weight after m months. After how many months will Mr. Wagner reach his goal of 220 pounds.
Answer:
y=mx+b
Step-by-step explanation:
In this case, x is represented by m. B is how much he weighs at the start which is 250. How many pounds does he lose per month ? 3. Thus, we conclude:
220=3x+250
Answer:
10 months
Step-by-step explanation:
220+3m = 250
Subtract 220 from both sides, now it is 3m=30. So now divide 3 on both sides. So now we have our answer m=10.

a random sample of 21 students from the U and at A&T were surveyed about their music listening habits. Their responses (in hours, each square represents 0.5 hour) were recorded and displayed using the following histograms. The left represents U. The right represents SHSAT. Which data set(U or SHSAT students) has a larger standard deviation? Explain.
Answer: U
Step-by-step explanation:
Looking at the graphs, U is skewed right and SHSAT is more of a normal distribution. Generally, this means the standard deviation would be greater for the data set that is skewed.
Let's find the standard deviation for each data set to confirm our theory.
Step 1) Find the mean number of hours
Step 2) Subtract each data value from the mean
Step 3) Find the mean of Step 2
U
hours x frequency: 1(3) + 2(5) + 3(4) + 4(3) + 5(3) + 6(2) + 9(1) = 72
Step 1: mean = (hours x frequency)/frequency = 72/21 = 3.4
Step 2: 2.4(3) + 1.4(5) + 0.4(4) + 0.6(3) + 1.6(3) + 2.6(2) + 5.6(1) = 33.2
Step 3: standard deviation = (sum from step 2)/ frequency = 33.2/21 = 1.58
SHSAT
hours x frequency: 1(1) + 2(3) + 3(4) + 4(5) + 5(3) + 6(3) + 7(2) = 86
Step 1: mean = (hours x frequency)/frequency = 86/21 = 4.1
Step 2: 3.1(1) + 2.1(3) + 1.1(4) + 0.1(5) +0.95(3) + 1.9(3) + 2.9(2) = 28.5
Step 3: standard deviation = (sum from step 2)/ frequency = 28.5/21 = 1.36
The calculations confirm that U has the greater standard deviation
