Solve the following A/5+3=8
Answer:
Your answer is going to be a=1
Step-by-step explanation:
First things first, we want all the letters on the left side and all the numbers on the right side. So, you have to get rid of the three. In order to get rid of the three you have to take it away, so A/5=8-3. Then it will become A/5=5. After that you want to have A all by itself so divide it by 5, A/5=5/5. Then it will become A=1. Hope this helps! :)
Answer:
A=25
Step-by-step explanation:
A/5+3=8
A/5+3-3=8-3

Answer:
1 and 2
Step-by-step explanation:
If x is 1: 2 x 1 + 7 = 2 + 7
= 9 This works.
If x is 2: 2 x 2 + 7 = 4 + 7
= 11 This works
If x is 3: 2 x 3 + 7 = 6 + 7
= 13 This does not work since 2x + 7 has to be less than 13.

What is the sum of the exterior angles of a 10-gon figure?
Answer:
The sum of the exterior angles of a regular polygon will always equal 360 degrees.
find the measure of m
Answer:
m=42
Step-by-step explanation:
because all straight line equal 180, we can find angle C
180-98=82
now, all triangles add up to 180. If we add up all the values we can find x
82+6x+8+5x+2=180
92+11x=180
11x=88
x=8
Now, just plug the variable into the angle measure
5(8)+2
40+2

Many families in California are using backyard structures for home offices, art studios, and hobby areas as well as for additional storage. Suppose that the mean price for a customized wooden, shingled backyard structure is $3,200. Assume that the standard deviation is $1,200. (a) What is the z-score for a backyard structure costing $2,300
Answer:
-0.75
Step-by-step explanation:
To get the z score we have to use this formula
Z = X-mean/standard deviation
X = 2300
Mean = 3200
The standard deviation = 1200
When we plug these values into the z formula above, we have:
2300-3200/1200
= -900/1200
= -0.75
the z-score for a backyard structure costing $2,300 is therefore -0.75
Write 3/5 as a division
Answer:
3/5 as a division is 0.6
Step-by-step explanation:
To write a fraction as a division, we basically divide the values, since the fraction represents a division.
In this question:
We want 3 divided by 5.
3 is less than 5, so we can multiply 3 by 10(getting 30), and adding a 0 to the quotient.
So now 0.(30/5) = 0.6, which means that 3/5 as a division is 0.6.
If three-fifths of seventh-grade class has missed at least one day of school, what percentage of 7th grade has missed at least a day of school?
The percentage of 7th grade class who has missed at least a day of school is 60 percentage.
What is percentage?
A percentage is a number or ratio expressed as a fraction of 100.
It is usually represented by using the symbol %
Given data ,
Fraction of 7th grade class that missed at least one day of school = 3 / 5
Now , to calculate the percentage of 7th grade that has missed at least one day of school , we multiply the fraction by 100
Therefore , Percentage = 3 / 5 x 100 %
= 3 x 20 %
= 60 %
Hence , the percentage of 7th grade class who has missed at least a day of school is 60 percentage.

What is mzA? Enter your answer as only a number
Answer:
A = 25
B = 65
Step-by-step explanation:
Remark
I hope you mean what is the size of <A? If not leave a note. If I am correct than A and C are complementary (equal 90o) since B is a right angle.
Solution
2x + 1 + 5x + 5= 90 Combine like terms
7x + 6 = 90 Subtract 6 from both sides
7x = 90-6
7x = 84 Divide by 7
x = 84/7
x = 12
==========================
Now that is not quite the answer.
A = 2x + 1
A = 2*12 + 1
A = 25
B = 5x + 5
B = 5*12 + 5
B = 60 + 5
B = 65

A jewelry box contains two gold hoop earrings and two silver hoop earrings. You randomly choose two earrings. What is the probability that both are silver hoop earrings? Write your answer as a fraction or percent rounded to the nearest tenth.
The probability that both are silver hoop earrings is:
Answer:
2 + 2 = 4 total earrings in the box.
If you put the earring back into the box before taking out the second, it would be 1/2 * 1/2 = 1/4, 25%.
Answer:
1/6 or 16.7%
Step-by-step explanation:
There are a total of 4 earrings in the box: 2 pairs of earrings + 2 pairs of earrings.
If you return the first earring to the box before removing the second, the answer is 1/2 * 1/2 = 1/4, or 25%.
If you remove the first earring from the package, the response is 1/2 * 1/3 = 1/6, or 16.7%.
The price of an item has been reduced by 15%. The original price was $87.
Answer:
The new cost is $73.95
The discount was $13. 05
Step-by-step explanation:
Turn the % into a decimal so it would be 0.15.
Then multiply it to the total, 87 x 0.15 = 13. 05
so the discount subtracted $13.05 off of the original price.
87 - 13. 05 = 73.95
The sum of two numbers is 12 times larger than one set and 29 times larger than the other set. What are those numbers and what is their sum?
Answer:
Step-by-step explanation:
This is a very impossible question to solve because we are not given any idea what both sets are, or at least either of them is. And thus, even if we write down an inequality equation, I doesn't solve the question, it rather makes one ask more questions.
If the two numbers are, say, a and b, and the first set is x, while the second set is y then we have an inequality in the sense that
a + b = 12x
a + b = 29y
How to proceed with no idea what x or y is, is well, not possible
