An equation shows the relationship between variables and other quantities in a situation, by equating the constraints of the situation.
The variable is the unknown part of the equation that can take any value according to the equation.
Properties of an equation can be defined as-
They are the expression which consist the variables, coefficients of variables and constants having an equal sign in between.
The example of an equation can be given as:
y = 5 x + 10
Lets assume here that the variable (y) represent the charge of taxi and variable (x) represent the number of rides the taxi traveled.
Here the constant 10 is the fixed amount which is charged by the taxi driver and coefficient of (x) 5 is the rate by which the the value of x increases with respect to y.
Therefore, an equation shows the relationship between variables and other quantities in a situation, by equating the constants of the situation.

Benny wants to buy a new video game that costs $49.95. He already saved $24.65, and his aunt gave him $15 for mowing her lawn. How much more money does Benny need to buy the video game?
Answer:
$10.30

Your job is to sort and sack marbles for sale a bag contains 55 marbles some red and some green if there are 11 red marbles what is the ratio of red to green marbles?
Answer:
1:4
Step-by-step explanation:
There are only two colours available, red and green. We know that there are 11 red marbles and 55 marbles altogether, so the number of green marbles must be 55 - 11, or 44. That means that the ratio of red to green marbles is 11:44, or 1:4.

Step-by-step explanation:
In a high school, 28% of the school’s population is seventeen years old. Of the students who are seventeen years old, 44% play a sport. One student at the high school is chosen at random to represent the school at a community event. What is the probability that the selected student will be seventeen years old and not play a sport?
Answer:
15.68%
Step-by-step
Since 44% of the 28% play sport subtract 44 from 100 to see how many of the 28% do not play sports and you get 56%. So multiply 56% and 28% and you get 15.68%.

Which of the following does not have the same value as the whole number 4?
3 5/5
1/4
4/1
3 4/4
Answer:
B
Step-by-step explanation:
3 5/5 = 4 because 5/5 is equal to 1, and 3+1 = 4.
1/4 is not equal to 4 because it is equal to 0.25
4/1 = 4 because it is an identity
3 4/4 = 4 because 4/4 is equal to 1, and 3+1 = 4
5. Which image in the collage to the right is an
example of an object not doing work?
O A. climbing a rock wall
B. a water wheel in a dry river
C. kicking a soccer ball
D. carrying a bicycle down the stairs
Answer:
B. A water wheel in a dry river
Step-by-step explanation:
Work is said to be done when a force moves a body or an object through a certain distance in the direction of the force. Thus for work to be done, force and distance are required.
i.e Work done = Force x distance
It is measured in Joules.
Also, the work done by an object could be a measured of potential energy.
So that,
Work done = potential energy = mass x gravitational force x height
Considering the collage in the question, since the water wheel is in a dry river no work is done. Water wheel is a device that functions through the flow of water body, thus causing its rotation.

What is the rate of change of y with respect to x?
Check the picture below.
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
to get the slope of any straight line, we simply need two points off of it, let's use those in the picture below.
[tex](\stackrel{x_1}{0}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{-3}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-3}-\stackrel{y1}{3}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{0}}} \implies \cfrac{-6}{2}\implies \LARGE \begin{array}{llll} -3 \end{array}[/tex]

Please!!! Help me plzz
Answer:
i thinks or might be the correct
Answer:
The correct answer is [tex]\frac{or}{and} \\[/tex].
Step-by-step explanation:
Part 1: The sign "<" means "less than." Therefore, "or" makes the most sense because there is only one option if you use this sign: the number on the left has to be smaller than the number on the right.
Part 2: The sign [tex]\leq[/tex] means "less than or equal to." Therefore, "and" makes the most sense because there are two options if you use this sign: the number on the left can be either smaller than or equal to the number on the right.
Therefore, the correct answer is [tex]\frac{or}{and} \\[/tex].

13 is no more than 5 less than a number. What is the minimum value of the number?
Answer:
18 is the minimum value.
Step-by-step explanation:
Set up an equation:
13 [tex]\leq[/tex] x - 5
Add 5 on both sides to isolate x:
(13) + 5 [tex]\leq[/tex] (x - 5) + 5
18 [tex]\leq[/tex] x
X can be equal to or greater than 18 so the minimum value of the number is 18.

The price of silver has increased by 25% per year from 2000. In the year 2000,Harry bought a silver bowl for $170. Write a function F(x) that can be used to represent the price of the bowl in x years after 2000
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The price of silver has increased by 25% per year from 2000. In the year 2000, Harry bought a silver bowl for $170.
To calculate the price of the silver bowl after x years, we need to use the following formula:
F(x)= PV*(1+g)^x
F(x)= future value
PV= present value
g= growth rate
x= number of years
For example, we determine the value of the coin after 10 years:
F(x)= 170*(1.25^10)
F(x)= $1,583.25
Answer:
F(x)= 170*(1.25^10)
F(x)= $1,583.25

A tile pattern has 5 tiles in figure 0 and adds 7 tiles in each figure, write a linear equation that represents this pattern
Answer:
The equation is:
y = 7x + 5
Step-by-step explanation:
Given
Figure 0 = 5 tiles
Figure 1 = 5+7 = 12 tiles
Given that it adds 7 titles in each figure. Thus, the rate of change = 7 tiles
Thus, the equation is:
y = 7x + 5
Here
7 is the rate change or slope of the equation.VERIFICATION:
setting x = 0 to determine the tiles in figure 0
y = 7x + 5
y = 7(0) + 5
y = 5
Thus, the figure 0 has 5 tiles
setting x = 1 to determine the tiles in figure 1
y = 7x + 5
y = 7(1) + 5
y = 7 + 5
y = 12
Thus, the figure 0 has 12 tiles (5 plus 7 added)
