Katelyn is training for a marathon. This week she ran 6 miles less than 2 times the number of miles she ran the previous week. She ran a total
of 42 miles in the two weeks.
Which system of equations can be used to find the number of miles she ran this week, r, and the number of miles she ran the previous week,
p?
Answer:
The system of Equations =
r = 2p - 6........ Equation 1
r + p = 42 ........Equation 2
Hence:
the number of miles she ran this week = r = 26 miles
the number of miles she ran the previous week = p = 16 miles
Step-by-step explanation:
Let the number of miles:
the number of miles she ran this week = r
the number of miles she ran the previous week = p
Katelyn is training for a marathon. This week she ran 6 miles less than 2 times the number of miles she ran the previous week.
r = 2 × p - 6 miles
r = 2p - 6........ Equation 1
She ran a total of 42 miles in the two weeks.
r + p = 42 miles
r + p = 42 ........Equation 2
Which system of equations can be used to find the number of miles she ran this week, r, and the number of miles she ran the previous week,p?
The system of Equations =
r = 2p - 6........ Equation 1
r + p = 42 ........Equation 2
We substitute 2p - 6 for r in Equation 2
2p - 6 + p = 42
3p = 42 + 6
3p = 48
p = 48/3
p = 16 miles
Solving for r
r = 2p - 6........ Equation 1
r = 2(16) - 6
r = 32 - 6
r = 26 miles
Hence:
the number of miles she ran this week = r = 26 miles
the number of miles she ran the previous week = p = 16 miles

8. The high school FFA is selling fruit. Together, Kay and Ayan sell a total of 25 boxes. Kay sells 13 less than Ayan.
How many boxes does each girl sell?
Define your variables:
X =
Y =
boxes.
boxes, and Ayan sold
Kay sold
Answer:
Kay sold 6 boxes and Ayan sold 19 boxes
Step-by-step explanation:
Let x = number of boxes Kay sells
y = number of boxes Ayan sells
Then the equations will be:
[tex]x+y = 25\\x = y-13[/tex]
We can solve the system by using substitution method
Putting x = y-13 in equation 1
[tex]y-13+y = 25\\2y -13 = 25\\2y = 25+13\\2y = 38[/tex]
Dividing both sides by 2
[tex]\frac{2y}{2} = \frac{38}{2}\\y = 19[/tex]
Putting y = 19 in equation 2
[tex]x = y-13\\x = 19-13\\x = 6[/tex]
Hence,
Kay sold 6 boxes and Ayan sold 19 boxes
Need help with this question, thanks.
Answer:
AE
Step-by-step explanation:
Times 11 for all sides get
11<x+13<33
then 11<x+13
-2<x
x+13<33
x<20
so
-2<x<20
so

Is 5/18 a rational number ?
Answer:
5/18 is a rational number because a rational number is any integer,fraction terminating decimal,or repeating decimal.
5/18 is rational number.
What is Rational Number?The word "ratio" is where the word "rational" first appeared. Rational numbers are therefore closely tied to the idea of fractions, which stand for ratios. In other terms, a number is a rational number if it can be written as a fraction in which the numerator and denominator are both integers.
Any number of the form p/q, where p and q are integers and q is not equal to 0, is a rational number. The letter Q stands for the set of rational numbers. Look at the following illustration to see what a rational number looks like.
Given:
5/18
For rational we need to first divide the fraction and then check whether the fraction is a decimal or not.
Or if it is a decimal then it is terminating or non terminating
5/18 = 0.2777777777777778
Hence, it is terminating because rational number is any integer, fraction terminating decimal or repeating decimal.

En una baraja completa de naipes ingleses (108 naipes), se selecciona un naipe, ¿Cuál es la probabilidad de que esta sea un joker rojo?
Por cada baraja de naipes de 54 cartas hay 1 joker rojo. Si esta baraja tiene 108 cartas, entonces habran 2 joker rojos.
Probabilidad de sacar 1 joker rojo = 2 / 108 = 1 / 54 = 0.185185 = 1.85%
En las votaciones para alcalde de la ciudad "Copito de Nieve" en una de las urnas, la probabilidad de sacar un voto para el candidato A es de 0,3, mientras que la probabilidad de obtener un voto para el alcalde B es de 0,5 ¿Cuál es la probabilidad de seleccionar un voto nulo o blanco?
probabilidad de sacar un voto nulo o blanco = 1 - probabilidad de sacar un voto para el alcalde B - probabilidad de sacar un voto para el candidato A = 1 - 0.5 - 0.3 = 0.2 = 20%
La probabilidad de que, al seleccionar una persona, esta guste del basquetbol es de 0,5, la probabilidad de que esta guste del futbol es de 0,7, la probabilidad de seleccionar a alguien que guste de alguno de los dos deportes es del 0,85 ¿Cuál es la probabilidad de seleccionar a una persona que guste de ambos deportes?
probabilidad que le gusten los dos deportes = probabilidad que le guste el futbol x probabilidad que le guste el basquetbol = 0.5 x 0.7 = 0.35 = 35%

What is the equation of the line in slope-intercept form?
Answer:
y = 4/3x + 4
Step-by-step explanation:
y = mx + b is the formula for finding the slope intercept form equation
m = slope
b = y intercept
If you look at points (-3, 0) and (0, 4), you can calculate the slope
You have to go over, from point (-3, 0), 3 times, and up four to get to the point (0, 4)
Slope is change in y over change in x, so, if we look to see where the line crosses the y-axis, or vertical axis, we can see it reach the number four on the y-axis, b = 4
Now, lets create your equation...
y = 4/3x + 4

This month the Middle School Media newspaper has 25 pages. Twenty-five schools order the paper for each of their students. Each of the schools has 25 classrooms with 25 students in each classroom. What expression with an exponent shows the total number of pages in all of the newspapers? Explain how you found the answer. Use words, numbers, and/or pictures to show your work. Write your answers on the paper provided. I will give brainiest to best answer.plz help
Answer:
The total number of pages in all the newspaper is 390,625 pages
Step-by-step explanation:
The number of pages in the newspaper = 25 pages
The number of schools ordering the newspaper = 25 schools
The number of class rooms in each school = 25 classrooms
The number of students in each classroom = 25 students
Therefore;
The total number of pages in all the newspaper = 25 pages per paper × 25 schools × 25 classroom per school × 25 students per classroom
The total number of pages in all the newspaper = 25 × 25 × 25 × 25 = 25⁴
The total number of pages in all the newspaper = 25⁴ = 390,625 pages
