Carla roller skates 3 miles each weekday and 5 miles each day on the weekend.Which expression represents how many miles she roller skates in w weeks?
Answer:
23w
Step-by-step explanation:
For 6days, She skates 3 * 6 = 18 miles
on weekend she skates 5 miles
Thus, In one week, she skates 23miles
In w week, she skates: 23w
in this exercise we have to know conversion, so it will be necessary to correct the space in time, which will represent in weeks:
28 weeks
So first, we have to calculate the total distance traveled in every day, like this:
[tex]days: 6*3=18\\weekends: 5*2=10\\total:18+10=28[/tex]

If b is a perfect square, which represents the solutions to the equation?
HELP PLEASE
Answer:
[tex]\{\sqrt b, -\sqrt b\}[/tex]
Step-by-step explanation:
Given
[tex]a^2 - b = 0[/tex]
Required
Determine the solution
Since b is a perfect square, the equation can be expressed as:
[tex]a^2 - (\sqrt b)^2 = 0[/tex]
Apply difference of two squares:
[tex](a - \sqrt b)(a + \sqrt b) = 0[/tex]
Split:
[tex](a - \sqrt b)= 0 \ or\ (a + \sqrt b) = 0[/tex]
Remove brackets:
[tex]a - \sqrt b= 0 \ or\ a + \sqrt b = 0[/tex]
Make a the subject in both equations
[tex]a =\sqrt b \ or\ a =-\sqrt b[/tex]
The solution can be represented as:
[tex]\{\sqrt b, -\sqrt b\}[/tex]

How might doing math slowly help with problems that are difficult to understand or hard to solve?
Q: How might doing math slowly help with problems that are difficult to understand or hard to solve?
A: It calms you down. When you are stressed, you are most likely to get it wrong because you are panicking. This also helps because you can read the problem correctly and make sure you are doing it right, because in math, If you get 1 small thing wrong, you usually get the entire thing wrong.

Find the GCF for the list.
−15x^3 , 6x^4
Answer:
the GCF is 3x^3
Step-by-step explanation:
Identifying the greatest common factor of an expression like this one involves finding the GCF of each term when the terms are placed side by side: the GCF of -15x^3 and 6x^4 is 3x^3, because 3 and x^3 are the largest factors of their type (constant, power of x) that will divide evenly into -15x^3 and 6x^4.
The end result is 3x^3(-5, 2x). Once again, the GCF is 3x^3.

The graph of the function f(x) is shown on the corrdinate plane.
Which value is closest to f^-1(7)?
A-5
B-3
C,3
D, 5
The closest to the inverse notation is (d) 5
How to determine the closest to the inverse notationFrom the question, we have the following parameters that can be used in our computation:
The graph of the function f(x)
The notation f'(7) implies that we determine the inverse of the function
From the graph, we have the following equation
f(5) = 7
This means that
f^-1(7) = 5
Hence, the closest is (d) 5

You are paying off a student loan in monthly installments. After
the 4rd payment the remaining balance is $13,900. After the 5th
payment your remaining balance is $13,500. If n is the number of
payments that have been made, what is the nth term rule?
Answer:
The loan will be paid after 39 monthly installments.
Step-by-step explanation:
Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:
13900 - 13500 = 400
400 x 5 = 2000
2000 + 13500 = 15500
15500/400 = 38.75
Thus, the loan will be paid after 39 monthly installments.
