Answer:
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
−3/8÷−11/4
Applying the fractions formula for division,
=−3×4 / 8×−11
=−12/88
Simplifying -12/-88, the answer is
=3/22

14 minus the product of a number and 15
Answer:
14 - (y x 15)
Step-by-step explanation:
This is the number because:
1) 14 minus means 14 subtracted from the product of a number and 15
2) The product of a number and 15 is a variable multiplied with 15
3) Finally, if we put these together, we get 14 - (y x 15)

Solve 4(2x - 9) = 3x + 4
Answer:
x = 8
Step-by-step explanation:
First, you distribute
4(2x)+4(-9)=3x+4
8x - 36 = 3x + 4
Subtract 3x from both sides
(8x - 3x) - 36 = (3x - 3x) + 4
5x - 36 = 4
Then add 36 to both sides
5x (-36 + 36) = (4 + 36)
5x = 40
Then divide 5 from both sides
x = 8

Paulo has 39 patches from states he and his relatives have visited he wants to pin the onto a board and arrange them equally in 3 rows how many patches will be in each row
Given:
Total number of patches = 39
Total number of rows = 3
To find:
The number of patches in each row.
Solution:
We have,
Total number of patches = 39
Total number of rows = 3
We need to divide the total number of patches by total number of rows to find the number of patches in each row.
[tex]\text{Number of patches in each row}=\dfrac{39}{3}[/tex]
[tex]\text{Number of patches in each row}=13[/tex]
Therefore, the number of patches in each row is 13.

A televison that regularly sells for $749 is
marked down 15%. After it doesn’t sell, it is
reduced another 20% from the sale price. What
is the total savings from the original price?
Answer:
$239.68 or 32%
Step-by-step explanation:
749÷100=7.49 7.49×85=636.65
636.65÷100=6.3665
6.3665×80=509.32
cost after both reductions= $509.32
749-509.32=239.68
total savings =$239.68 or 32%

Find the equation of the line shown above.
Answer:
y = x + 6
Step-by-step explanation:
The equation for a line in y-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The slope of the line shown is 1/1 (which simplifies to 1).
The y-intercept is 6.
You would write the equation as y = x + 6.

Caroline is planting flowers in her garden. She plants her first 7 flowers in 4 minutes. After 12 minutes, she has planted 21 different flowers.
Which equation represents this direct variation?
The answer is B) y= 7/4x
This is because when you graph it you would go up 7 and over 4- you just had to find the rise over run. I also just made sure it was correct on edmentum!
Caroline is planting her first 7 flowers in 4 minutes and then past 12 minutes, she plants 21 different flowers. That suggests that she is planting the flowers following the given equation y=(7/4)x.
What is dependant variable?The dependent variable is defined as the variable whose evaluation of the independent variable determines the quality of the dependent variable. That is, it is consistently claimed that the word variable's estimate depends on the mathematical condition's free variable.
How to solve it?Let Caroline plant y flowers in x minutes.
By using the unitary method we can observe that
4 minutes → 7 flowers
⇒ 1 minute → 7/4 flowers
⇒ x minutes → (7/4)x flowers
Hence, Caroline is planting y=(7/4)x flowers in x minutes. And y=(7/4)x this equation represents the variation perfectly.
NOTE: We took the number of flowers planted as y because it is a dependent variable. The number of flowers depends on the time elapsed.

Let U be the set of cities in the U.S., A be the set of cities with a professional sports team, and B be the set of cities with a symphony
(3) Describe the complement of A
(4) Describe the union of A and B
(5) Describe the intersection of A and B
Answer:
A', is the set of all elements in the given universal set U .
But the union of sets is an operation performed on two sets, say A and B, which results in a set that has all elements belonging either to set A and set B or both. The operand of union of set is given by '∪'. You can see, U is also a set which collectively shows all the elements of A, B and of itself.
