Answer:
y = 1, x = -8
Step-by-step explanation:
[tex]x + 8y = 0\\-4x - 10y = 22[/tex]
we can multiply the top equation by 4 and cancel out the x's
[tex]4x + 32y = 0\\-4x - 10y = 22\\22y = 22\\y = 1[/tex]
[tex]x + 8(1) = 0\\x = -8\\-4(-8) - 10(1) \\32 - 10 = 22\\[/tex]
Which sentence is a statement of the Multiplicative IdentityProperty? A. The sum of any realnumber and its opposite is zero. B. The product of any realnumber and its reciprocal is one. C. The sum of zero and any other realnumber is the number itself D. The product of one and any other realnumber is the number itself.
Answer:
D. The product of one and any other real number is the number itself.
Step-by-step explanation:
Multiplicative Identity Property can also be referred to as the identity property.
It states that when a number , a real number is multiplied by 1, the result is that same real number itself.
For example:
2 × 1 = 2
-5 × 1 = -5
Therefore, option D. The product of one and any other real number is the number itself. Is the correct option.

Step-by-step explanation:
You run 2 1/2 miles as a part of an exercise routine. You run 1/3 of that distance on a hill. You run down a slope for the last 1/2 of the hill. On how many miles of your run do you run down the slope? Write your answer as a fraction or mixed number in simplest form.
Given:
Total distance for daily exercise is [tex]2\dfrac{1}{2}\text{ miles}[/tex].
You run 1/3 of that distance on a hill.
You run down a slope for the last 1/2 of the hill.
To find:
The distance you run down the slope.
Solution:
We have,
Total distance [tex]=2\dfrac{1}{2}\text{ miles}[/tex]
You run 1/3 of that distance on a hill.
Distance on a hill [tex]=\dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]
You run down a slope for the last 1/2 of the hill.
Distance you run down the slope [tex]=\dfrac{1}{2}\times \dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]
[tex]=\dfrac{1}{6}\times \dfrac{2\times 2+1}{2}\text{ miles}[/tex]
[tex]=\dfrac{1}{6}\times \dfrac{5}{2}\text{ miles}[/tex]
[tex]=\dfrac{5}{12}\text{ miles}[/tex]
In cannot be expressed as mixed fraction because 5<12.
Therefore, the distance you run down the slope is [tex]\dfrac{5}{12}\text{ miles}[/tex].
if you deposit $1,000 into an account with 4% interest, how much money will be in the account in three years
Answer:
$1124.86
Step-by-step explanation:
1000(1+0.04)^3=1124.864
Answer:

4% of 1,000 is 40
$40*3 years is 120
add that to 1000 and you get 1,120
Martha put $4.84 in her coin bank. Each day she added 1 quarter, 1 nickel and 6 pennies how much does she add each day? How much money was in her coin bank after 6 days?
Answer:
-Martha would add $0.36 each day.
-Martha would have $7 in her coin bank after 6 days.
Step-by-step explanation:
1 quarter= $0.25
1 nickel= $0.05
1 penny= $0.01
To find the amount she adds each day, you have to add the results of multiplying each coin added on a day for its value:
1*0.25+1*0.05+6*0.01=0.25+0.05+0.06=0.36
This means that Martha would add $0.36 each day.
Then, to find the amount of money that was in her coin bank after 6 days, you have to add the amount she put on the coin bank plus the amount she added each day for the number of days:
$4.84+($0.36*6)=$4.84+$2.16=$7
According to this, Martha would have $7 in her coin bank after 6 days.

Jaylenʻs betta fish tank holds 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. What is the flow rate of the water in gallons per minute? Show your work.
Answer:
2.4 gallons every minute
Step-by-step explanation:
Since we are given three values and one variable that needs to be solved in a ratio problem we can use the Rule of Three to solve for the flow rate of the water with this being represented as x.
4 [tex]\frac{1}{2}[/tex] or 4.5 gallons <============> 1 [tex]\frac{7}{8}[/tex] or 1.875 minute
x gallons <==============> 1 minute
(1 * 4.5) / 1.875 = x
2.4 gallons = x
Therefore, we can see that the flow rate is 2.4 gallons every minute, meaning that every single minute that the hose is on, it will deposit 2.4 gallons of water into the fish tank.

Convert 3.16 repeating to a fraction. Explain your strategy or show steps you used to convert the number.
What is 3.16161616161616161616 as a fraction?
To write 3.16161616161616161616 as a fraction you have to write 3.16161616161616161616 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
3.16161616161616161616 = 3.16161616161616161616/1 = 31.616161616162/10 = 316.16161616162/100 = 3161.6161616162/1000 = 31616.161616162/10000 = 316161.61616162/100000 = 3161616.1616162/1000000 = 31616161.616162/10000000 = 316161616.16162/100000000 = 3161616161.6162/1000000000 = 31616161616.162/10000000000 = 316161616161.62/100000000000 = 3161616161616.2/1000000000000 = 31616161616162/10000000000000
And finally we have:
3.16161616161616161616 as a fraction equals 31616161616162/10000000000000
Step-by-step explanation:
3.16161616 ... = 313 99 = 3 16 99
Explanation: It appears that you mean 3.16161616 ... , let x = 3.16161616 ... , then 100 x = 316.16161616 ...
Subtracting former from latter we get 99 x = 313 and x = 313 99 = 3 16 99 Hence 3.16161616 ... = 3 16 99

Daisy pompt 7 strandballen op waarvoor ze 100 l lucht nodig heeft, wat is de straal van deze strandballen? R= straal/ i= inhoud in liter formule: 1= 4/3x pi x r³
Antwoord:
r = 0,288m
Stapsgewijze uitleg:
Volume van de strandballen V = 4 / 3πr³
1 liter = 0,001 cm³
100l = x
x = 100 * 0,001
x = 0,1 m³
Vervangen in de formule en verkrijg de straal
0,1 = 4 / 3πr³
0,3 = 4πr³
r³ = 0,3 / 4 (3,14)
r³ = 0,3 / 12,56
r³ = 0,02388
r = ∛0,02388
r = 0,288m
Vandaar dat de straal van de strandballen 0.288m is
If the diagonals of a parallelogram are congruent then what would be the best and
most restrictive description of that quadrilateral?
a) Kite
b) Rectangle
c) Trapezoid
d) Rhombus
=======================================================
Explanation:
If the diagonals were congruent, then you can use the SSS property to prove a pair of right triangles are congruent. This leads to showing that we have adjacent congruent corresponding angles. Let's call those angles x and y.
Since they are congruent, we know that y = x. Adjacent angles of any parallelogram add to 180, so x+y = 180
By substitution we can solve for x
x+y = 180
x+x = 180
2x = 180
x = 180/2
x = 90
So y = 90 as well.
This line of thinking is used to show that all four angles of this parallelogram are 90 degrees. A rectangle is any quadrilateral in which all four angles are 90 degrees, so that's why this parallelogram is a rectangle.

Solve using Elimination:
7x + 2y = 24
4x + y = 15
Solution = ( , )
Answer:
(6, -9)
Step-by-step explanation:
Eliminate y (you can do x too, but y is easier for this problem)
To eliminate y we must get 0y
If one is 2y, the other must be -2y to get to 0
Keep the first equation the same
7x + 2y = 24
Multiply all numbers in the second equation by -2 (so y can be -2y)
-8x + -2y = -30
Positive + Negative = Negative
-8x - 2y = -30
Now add/subtract the two equations from each other
7x + 2y = 24
-8x - 2y = -30
-1x + 0y = -6
-1x = -6
Divide both sides by -1 to isolate variable
-1x ÷ -1 = -6 ÷ -1
x = 6
We could simply plug in the x value into one of the equations, but that's substitution - not elimination. Repeat the same steps for x
I will multiply the first equation by 4 to get 28x and the second equation by -7 to get -28x for an answer of 0x
28x + 8y = 96
-28x - 7y = -105
0x + 1y = -9
1y = -9
Divide both sides by 1 to isolate the variable
1y ÷ 1 = -9 ÷ 1
y = -9

Complete question:
Russell has a collection of 1,200 pennies. Of these pennies, 25% are dated before 1980, 35% are dated from 1980 to 2000, and the rest are dated after 2000. How many pennies in Russell’s collection are dated after 2000?
Answer:
480 pennies
Step-by-step explanation:
Total pennies = 1200
Datwd before 1980 = 25%
Dated 1980 - 2000 = 35%
The rest are Dated after 2000 ;
How many are dated after 2000
Dated before 1980 = 25% ;
25% of 1200
0.25 * 1200 = 300
Dated 1980 - 2000 = 35% ;
0.35 * 1200 = 420
Dated after 2000 ;
1200 - (300 + 420)
1200 - 720
= 480 pennies

Approximate √31 with a decimal to the nearest hundredth. How does the square of that approximate compare to 31?
31 is between the square numbers 25 and 36, whose respective square-roots are 5 and 6. Lets take the median of 25 and 36 to see how far in the middle 31 is.
(25 + 36) / 2 = 61 / 2 = 30.5
This is close to 31.
Take the median of the square-roots.
(5 + 6) / 2 = 11 / 2 = 5.5 This is the median square-root.
Square-root of 31 is between 5.5 and 6.
√31 = 5.55
