a whole number by a unit fraction is the same as multiplying a whole number by the of the unit fraction.
Answer:
A whole number divided by a unit fraction is the same as multiplying a whole number by the inverse of the unit fraction.
Step-by-step explanation:
Given
[tex]8 \div \frac{1}{5} = 40[/tex]
[tex]8 * 5 = 40[/tex]
Required
Explain why both expressions are correct
No dropdown to select from. So, I will provide a general solution.
When a number is divided by a fraction.
Take for instance:
[tex]8 \div \frac{1}{5}[/tex]
The above can be expressed as the product of the number and the inverse of the fraction.
The inverse of 1/5 is 5.
So, we have:
[tex]8 \div \frac{1}{5} = 8 * 5[/tex]
The result of the above expression is:
[tex]8 \div \frac{1}{5} = 8 * 5 = 40[/tex]

Function (f) is defined by the equation f(x)=3x-7. Find the value of c so that f(c) =20 is true.
Answer: C=9
explanation:
hope this helps
The value of c so that the function f ( c ) = 20 is when c = 9
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is given by
f ( x ) = 3x - 7
Now , substituting the value of f ( x ) = 20 , we get
when x = c
f ( c ) = 3c - 7
The value of the equation f ( c ) = 20
Substituting the value in the equation , we get
3c - 7 = 20
On simplifying the equation , we get
Adding 7 on both sides of the equation , we get
3c = 27
Divide by 3 on both sides of the equation , we get
c = 9
Therefore , the value of the variable c = 9
Hence , The value of c so that the function f ( c ) = 20 is when c = 9

Answer: 36.84
(lmk if this isnt right)
Step-by-step explanation:
To find the perimeter of the rectangle:
3+3+3+3+3+3=18
or
3(6)=18
To find the diameter of the circle:
12-(3+3)
12-6=6
You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.
C=πd
Substitute
C=3.14(6)
Multiply
C=18.84
Add the perimeter of the rectangle and the circumference of the circle.
18+18.84=36.84

Rachel found that the time it takes for her to make her favorite desert decreases the more times she makes its. The time is takes in minutes(M) can be modeled by: M=72-0.75n, where n is the number of times that rachel has made the desert.
A. how long will it take rachel to make her desert the fifth time?
B. after how many times will rachel be able to make her desert in 63 minutes?
C. How long will it take rachel to make her desert the 40th time? Do you think this is reasonable?
Answer:
A: 68.25 minutes
B: 12 times
C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.
Step-by-step explanation:
a: 72 -0.75*5 = 68.25
b: M=63=72-0.75n
subtract 72 from each side: -9 = -0.75n
divide each side by -0.75: n = 12
so 12 times
c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.
