Which expression is equivalent to 14x^8y^10
Answer:
The answer for this problem is 2xy^6 * 7x^7y^4 (C).
2x + y = 19
-2y - 2x = -22
please show step by step
Answer:
the value of x = 3 and y = 3
Step-by-step explanation:
2x + y = 9 ------------ (1)
-2y -2x = -22 ------------ (2)
Subtract (1) from (2)
-2x -2y = -22
2x + y = 19
----------------------
-y = -3
y = 3
Put the value of y in equation 1
2x + y = 9
2x + 3 = 9
2x = 9 - 3
2x = 6
x = 6/2
x = 3
Therefore, the value of x = 3 and y = 3

Answer:
2x / 5 = 4
x = 10
Step-by-step explanation:
Twice a number divided by 5 gives 4
2x / 5 = 4
2x / 5 = 4
Multiply both sides by 5
2x = 20
Divide both sides by 2
x = 10

A 13 inch piece of steel is cut into three pieces so that the second piece is twice as long as first piece, and the third piece is one inch more than three times the length of the first piece. Find the length of the piece
Answer:
The first piece is 2 inches, the second piece is 4 inches, and the third piece is 7 inches.
Step-by-step explanation:
Since a 13 inch piece of steel is cut into three pieces so that the second piece is twice as long as first piece, and the third piece is one inch more than three times the length of the first piece, to find the length of the pieces, the following calculation must be performed:
1 = X
2 = 2X
3 = 1 + 3X
X + 2X + 3X + 1 = 13
6X = 13 - 1
X = 12/6
X = 2
Therefore, the first piece is 2 inches, the second piece is 4 inches, and the third piece is 7 inches.

4th grade math question
Answer:
1 1/6
Step-by-step explanation:
the problem is asking you to do 1/6 7 times. Lets break it down and make it 1/6 plus 1/6 plus 1/6 plus 1/6 plus 1/6 plus 1/6 plus 1/6
so lets add the all the numerators 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 is 7
the numerator value is 7 and you dont add the denominator so it stays as 6
so the answer is 7/6 or 1 1/6 as a mixed number
Answer:1 1/6
Step-by-step explanation: The answer is one and one sixth because when you imagine that the 7 is over one, when you times it you get 7/6 and that is 1/ 1/6

The cost of a week long vacation in a city has a mean of 1000 and a variance of 1200. The city imposes a tax which will raise all tourism related costs by 10%. Find the coefficient of variation for the cost of a week long vacation in this city after the tax is imposed.
Answer:
The coefficient of variation after the tax is imposed is 0.033
Step-by-step explanation:
Given
[tex]\mu =1000[/tex] --- mean
[tex]\sigma^2 = 1200[/tex] --- variance
[tex]tax = 10\%[/tex]
Required
The coefficient of variation
The coefficient of variation is calculated using:
[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]
After the tax, the new mean is:
[tex]\mu_{new} = \mu * (1 + tax)[/tex]
[tex]\mu_{new} = 1000 * (1 + 10\%)[/tex]
[tex]\mu_{new} = 1100[/tex]
And the new variance is:
[tex]\sigma^2_{new} = \sigma^2 * (1 + tax)[/tex]
[tex]\sigma^2_{new} = 1200 * (1 + 10\%)[/tex]
[tex]\sigma^2_{new} = 1320[/tex]
So, we have:
[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]
[tex]CV = \frac{\sqrt{1320}}{1100}[/tex]
[tex]CV = \frac{36.33}{1100}[/tex]
[tex]CV = 0.033[/tex]

I need help I have been stuck on this for years. Plz anything helps
9514 1404 393
Answer:
see below
Step-by-step explanation:
Perhaps you're stuck because it is too simple. If any value in the x-column is repeated, the relation is not a function.
Of the two relations shown, the first is not a function (x=3 is repeated), and the second one is a function (all the x-values are different).

The whole journey took 5 h 24 min.
How far is the school from home, in
kilometres
A 9
B. 12
C. 24
D. 27
Answer:
12 km
Step-by-step explanation:
5h 24min = 5.4 hrtime = distance / speed--------------------------------
time out + time back = total time
d/5 + d/4 = 5.4
multiply both sides by 20 to clear the fractions
4d + 5d = 108
9d = 108
Divide both sides by 9
d = 12 km

28-8=20
hope that helped!!
Answer:
y = 8/27
Step-by-step explanation:
given
x = 7
y = 4x*y - 4(2)
y = 4*7*y - 8
y = 28y - 8
8 = 28y - y
8 = 27y
8/27 = y
to prove
y = 4x*y - 4(2)
8/27 = 4*7*y - 8
8/27 = 28*8/27 - 8
8/27 = 224/27 - 8
8/27 = 224 - 27*8/27
8/27 = 8/27
hence it is proved that y is 8/27 .

= 5/( -10+8)
= 5/-2

Your checking account is in debt $20. You use this account to make a $10 purchase. Then, you deposit $38 into the account. What is the balance of the checking account?
Answer: 8
Step-by-step explanation
Answer:
$8
Step-by-step explanation:
If we just keep track of the money in the account, we can solve this pretty quickly. If the balance is -20, and we subtract another 10 from it, it gives us -30. $38 is then deposited into the account, giving us a balance of $8.

La abuela de Jorge, cuando llegan las fechas navideñas, reparte 120 € entre los tres nietos de la siguiente forma: Jorge, como es el mayor, recibe 10 € más que su prima Alejandra, y esta 10 € más que la prima pequeña Marina. ¿Cuánto dinero recibe cada uno?
Answer:
Marina recibe 30 euros, Alejandra recibe 40 euros y Jorge recibe 50 euros.
Step-by-step explanation:
Dado que la abuela de Jorge, cuando llegan las fechas navideñas, reparte 120€ entre los tres nietos de la siguiente forma: Jorge, como es el mayor, recibe 10 € más que su prima Alejandra, y esta 10 € más que la prima pequeña Marina, para determinar cuánto dinero recibe cada uno se debe realizar el siguiente cálculo:
J = A + 10
A = M + 10
M = M
J + A + M = 120
A + 10 + M + 10 + M = 120
M + 10 + 10 + M + 10 + M = 120
3M + 30 = 120
3M = 120 - 30
M = 90 / 3
M = 30
Por lo tanto, Marina recibe 30 euros, Alejandra recibe 40 euros y Jorge recibe 50 euros.

Find the mean for the given sample data. Unless indicated otherwise, round your answer to one more decimal place than is present in the original data values. The local Tupperware dealers earned these commissions last month: $1077.28, $2661.13, $4642.11, $4264.15, $1019.55, $3444.20, $2525.92, $3740.26, $3533.07, $1633.84 What was the mean commission earned? Round your answer to the nearest cent.
Answer:
the mean commission earned is 2854.15
Step-by-step explanation:
The computation of the mean commission earned is shown below'
The mean is
= ($1077.28 + $2661.13 + $4642.11 + $4264.15 + $1019.55 + $3444.20 + $2525.92 + $3740.26 + $3533.07 + $1633.84) ÷ 10
= 2854.15
Hence, the mean commission earned is 2854.15
The same should be considered and relevant
