Answer:
The answer is "Ratio".
Step-by-step explanation:
A ratio indicates how often a number contains a different number. Whenever the calculation of two quantities, as often happens, is indeed a measurement ratio without dimension. It is called a quotient of two volumes, which is calculated by using various units.
It is the relationship among two or more elements of financial reports is calculated by ratios. These also are efficient when the outcomes are presented several times. It allows you to monitor the performance of your company over time and to detect signs of injury.

Find the solution to the system of equations below.
2y = 2x - 8
2x + y = 5
Answer:
The solution to the system of equations is:
(x, y) = (3, -1)The graph is attached below.
Step-by-step explanation:
Given the system of equations
[tex]2y = 2x - 8[/tex]
[tex]2x + y = 5[/tex]
Let us solve the system of equations using the elimination method
[tex]\begin{bmatrix}2y=2x-8\\ 2x+y=5\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}2y-2x=-8\\ y+2x=5\end{bmatrix}[/tex]
Multiply y + 2x = 5 by 2: 2y + 4x = 10
[tex]\begin{bmatrix}2y-2x=-8\\ 2y+4x=10\end{bmatrix}[/tex]
subtracting the equations
[tex]2y+4x=10[/tex]
[tex]-[/tex]
[tex]\underline{2y-2x=-8}[/tex]
[tex]6x=18[/tex]
solve 6x = 18 for x
[tex]6x=18[/tex]
Divide both sides by 6
[tex]\frac{6x}{6}=\frac{18}{6}[/tex]
simplify
[tex]x=3[/tex]
For 2y - 2x = -8 plug in x = 3
[tex]2y-2\cdot \:3=-8[/tex]
[tex]2y-6=-8[/tex]
Add 6 to both sides
[tex]2y-6+6=-8+6[/tex]
Simplify
[tex]2y=-2[/tex]
Divide both sides by 2
[tex]\frac{2y}{2}=\frac{-2}{2}[/tex]
Simplify
[tex]y=-1[/tex]
Therefore, the solution to the system of equations is:
(x, y) = (3, -1)The graph is attached below.

Answer:
13
Step-by-step explanation:
the two numbers that satisfy the requirements for this is 2 and 3, so the answer i put is the sum of the square of the two numbers.
Answer:
let two number be x and y
by question
x+y=5….....(1)

Alyssa estimates that her school's gym can hold 660 students. It actually has 750 seats. What is the percent error of her estimate?
Answer: 13.64%
Step-by-step explanation:
Alyssa estimates that the gym can hold 660 students even though it can hold 750.
Her percent error is calculated by:
= (Actual seats - Estimated seats) / Estimated seats
= (750 - 660) / 660
= 90 / 660
= 0.1364
= 13.64%
What does it mean
for one variable to be dependent on another
variable
Answer:
The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Step-by-step explanation:
The LCM of two numbers is 14 times their HCF. The sum of LCM and HCF is 600. If one number is 280, then find the other number.
Given:
The LCM of two numbers is 14 times their HCF.
The sum of LCM and HCF is 600.
One number is 280.
To find:
The other number.
Solution:
Let HCF of two numbers be x.
The LCM of two numbers is 14 times their HCF.
LCM = 14x
The sum of LCM and HCF is 600.
[tex]14x+x=600[/tex]
[tex]15x=600[/tex]
[tex]x=\dfrac{600}{15}[/tex]
[tex]x=40[/tex]
So, HCF = 40 and the LCM is
[tex]LCM=14(40)[/tex]
[tex]LCM=560[/tex]
We know that, if a and b are two numbers, then
[tex]a\times b=LCM(a,b)\times HCF(a,b)[/tex]
One number is 280.
[tex]280\times b=560\times 40[/tex]
[tex]b=\dfrac{560\times 40}{280}[/tex]
[tex]b=2\times 40[/tex]
[tex]b=80[/tex]
Therefore, the other number is 80.

For a walk-a-thon a sponsor committed to give you a flat free of $5 plus $2 for every mile m you walk
Answer:
$45
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION BELOW;
For a walk-a-thon a sponsor committed to give you a flat fee of $5 plus $2 for every mile you walk. If you walk for 20 miles, what is the total amount you will collect from your sponsor at the end of the walk-a-thon?
$5 was given for participants of the walk-a-thon.
$2 was given for every miles won
Then, for "y" number of miles, the the amount that can be won is ( 2×y)= 2y
The Total amount that can be given
= (5 + 2y)
Where "y" is the miles value
Then, if you walk for 20 miles, The Total amount that can be given
= 5 + 2(20)
= 5+ 40
= $45

Maya, Ahmad, and Joe served a total of 75 orders Monday at the school cafeteria. Joe served 2 times as many orders as Maya. Ahmad served 5 fewer orders
than Maya. How many orders did they each serve?
Total number of orders served by Maya, Ahmad and Joe on Moday = 75
Let the number of orders Maya served be x.
Then :
Number of orders Joe served = 2x
Number of orders Ahmad served = x - 5
This can be written in an equation as :
[tex] \tt \: 2x + x - 5 + x = 75[/tex]
[tex] = \tt 4x - 5 = 75[/tex]
[tex] = \tt 4x = 75 + 5[/tex]
[tex] = \tt 4x = 80[/tex]
[tex] = \tt \: x = \frac{80}{4} [/tex]
[tex] = \tt \: x = 20[/tex]
Which means :
Number of orders Joe served :
= 2 × 20
= 40
Thus, Joe served 40 orders.
Number of orders Maya served = 20
Number of orders Ahmad served :
= 20 - 5
= 15
Thus, Ahmad served 15 orders.
Therefore, Maya served 20 orders Ahmad served 15 ordersJoe served 40 orders.There are 1,775 pennies in Isaiah’s jar. If 25 pennies are needed to fill a bag, how many whole bags can Isaiah fill?

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 miles per hour slower than the westbound train. If the two trains are 400 miles apart after 2 hours, what is the rate of the eastbound train?
Answer:
Rate of the Eastbound train is 93 mph.
Step-by-step explanation:
Let the speed of the Eastbound train = x miles per hour
And the speed of the West bound train = y mph
Eastbound train travels 14 mph slower than the westbound train,
So the equation will be,
y - x = 14 ----------(1)
If these trains are 400 miles apart after 2 hours,
Distance traveled by the Eastbound train = Speed × Time
= 2x miles
Distance traveled by the Westbound train = 2y miles
Trains are 400 miles apart after 2 hours,
So the equation will be,
2y + 2x = 400
x + y = 200 ----------(2)
By adding equation (1) and equation (2)
(y - x) + (x + y) = 14 + 200
2y = 214
y = 107 mph
From equation (1)
107 - x = 14
x = 107 - 14
x = 93 mph
Therefore, rate of the Eastbound train is 93 mph.

If a Canada savings Bond is worth $6225 after 7 years, and was originally bought for $5000, what was the annual simple interest rate? Answer as a percentage.
[Formulas are,
[I = P, R, T]
[A = P + I]
[A = P(1 + R times T)
Answer:
3.5%
Step-by-step explanation:
Given data
A=$6225
P=$5000
T= 7years
R=???
Simple interest
A=P(1+rt)
substitute
6225=5000(1+7r)
6225=5000+35000r
collect like terms
6225-5000=35000r
1225=35000r
r= 1225/35000
r=0.035
Hence the rate is 0.035*100= 3.5%
