Answer:
w=7
Step-by-step explanation:
-12=9-3w
3w-12=9
3w=21
w=7
-12=9-21=-12
-12=-12
Answer:
X=7
Step-by-step explanation:
-12=9-3w
Subtract nine from both sides
-12=9-3w
-9. -9
-21=-3w
Divide by -3
-21/-3=7
X=7

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

a>b
a≥b
a≤b
a
Answer: a<b
Step-by-step explanation:
Given statement: "a number a is always less than another number b."
We use "<" or ">" sign to show less than or more than comparison in a mathematical statement.
If a is less than b then it can represented as
a < b
The expressions expresses the relationship between a and b would be:
a < b

A bathtub drains at a rate of 4 1/5 liters of water in 1/5 of a minute. How many liters of water does the bathtub drain per minute
Answer:
I think the answer is 252 liters a minute.
Step-by-step explanation:
I got 252 liters a minute because I had to first put 4 1/5 as a fraction and it was 21/5. In ever minute there are 60 seconds. I then multiplied 21/5 times 60 to get me to 252 liters. To double check your work you have to divide 252 by 60. When you divide 252 by 60 you would get 4.2 which reduces to 4 1/5 which makes 252 liters per minute the right answer. Hope this helps.
can someone pls help me? :)
Example:
2x + 4x - 3x = 18
6x - 3x = 18 (2x + 4x = 6x)
3x = 18 (6x - 3x = 3x)
x = 6 (18 divided by 3 = 6)
Example:
10s - 4 = 7s + 8
10s - 7s = 8 + 4
3s = 12 (12 divided by 3 = 4)
s = 4

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

how many 4-digit number are divisible by 7,8,10 and 25
9514 1404 393
Answer:
7
Step-by-step explanation:
In order for a number to be divisible by all of 7, 8, 10, and 25, it must be a multiple of the least common multiple of those numbers.
LCM(7, 8, 10, 25) = 7×8×25 = 1400
There are floor(10,000/1,400) = 7 4-digit numbers divisible by 7, 8, 10, and 25. They are ...
1400, 2800, 4200, 5600, 7000, 8400, 9800

Which of the following sentences is the word equivalent of the expression above?
A.The product between 3 and a number is no less than 9.
B.The product between 3 and a number is greater than 9.
C.The product between 3 and a number is no more than 9.
D.The product between 3 and a number is less than 9.
Answer:
Let's define the symbols:
x < y
means that x is strictly less than y.
x ≤ y
means that x is less than or equal to y.
(both of these signs can be in the other direction, take that in mind).
A) " a is always less than another number b"
Here we should have:
a < b.
a is always less than the other number b.
This is not in the options, so i suppose that there is a mistake in the question.
B) The expression "above" is not shown here, so i will just writhe the correspondent expression for each option, and you can see which one matches with the expression above.
a) "The product between 3 and a number is no less than 9"
3*n ≥ 9.
b) "The product between 3 and a number is greater than 9."
3*n > 9
c) "The product between 3 and a number is no more than 9"
3*n ≤ 9
d) "The product between 3 and a number is less than 9"
3*n < 9

En una baraja completa de naipes ingleses (108 naipes), se selecciona un naipe, ¿Cuál es la probabilidad de que esta sea un joker rojo? 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? 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?
Answer:
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%
