What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given are mathematical verbal problems based on equation modelling.
From the first problem, the cost of a single notebook is $3.
Now, consider Store {A}. Assume the cost of a single notebook be {x}. Then, according tot he question -
The cost of 4 notebooks is same as the cost of 3 notebooks and a $2 set of pencils. We can write it as -
The cost of 4 notebooks is same as : (3x + 2)
The cost of 4 notebooks is same as : (3x + 2)
The cost of one notebook will be equal to : (3x + 2)/4
So, we can write -
x = (3x + 2)/4
4x = (3x + 2)
4x - 3x = 2
x = 2
At store {A} the cost of notebook is $2.
Therefore, a different way that you could use to begin to solve the equations problem given is discussed above. I would you visit store {A} over the cost of the given store.

4 divided by 6 as a fraction draw picture
Figure A is a scale image of figure B.
Figure A maps to figure B with a scale factor of [tex]2/7[/tex]
The value if side x is 42
How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
Given;
Scale factor= 12
Now, to find the value of x;
We will divide 12 by the scale factor
=12/(2/7)
=(12x7)/2
=42
Therefore, with scale factor 2/7 the side x of figure A will be 42

An Uber ride costs $13.15 for a 3 mile trip and $18.25 for a 5 mile trip find the rate of the cost per mile
The cost per mile for both trips are $4.5 and $3.65
How to calculate the cost per mile ?An uber ride costs $13.15 for a 3 mile trip and $18.25 for a 5 mile trip
The cost per mile for both trips can be calculated as follows
The first step is to calculate the cost of mile for the First trip
13.15= 3
x= 1
cross multiply both sides
3x= 13.15
x= 13.15/3
x= 4.5
The next step is to calculate the cost of mile for the Second trip
18.25= 5
y= 1
cross multiply both sides
5y= 18.25
y= 18.25/5
y= 3.65
Hence the cost per mile for both trips are $4.5 and $3.65

M
3,600 s. 1,760 yd.
N
3,600 s. • 1,760 yd.
9 s. • 100 yd.
Answer: To find Usain's speed in miles per hour, we need to convert the distance from yards to miles and the time from seconds to hours. To convert yards to miles, we divide the number of yards by the number of yards in a mile (1,760). To convert seconds to hours, we divide the number of seconds by the number of seconds in an hour (3,600).
So, to find Usain's speed, we use the formula:
Speed = Distance / Time
In this case, we have:
Speed = (100 yd) / (9 s)
We need to convert yards to miles and seconds to hours, so we can use the following conversion factors:
1 yd = 1/1,760 mi
1 s = 1/3,600 hr
By applying this conversion factor we get the speed in miles/hour.
Speed = (100 yd) / (9 s) * (1/1,760 mi/yd) * (1/3,600 hr/s)
So the final answer will be:
Speed = (100/9) * (1/1,760) * (1/3,600) miles/hour
Hence, option M: 3,600 s is the final answer.

A carpenter installing cabinets uses thin pieces of material called shims to fill gaps. The carpenter uses four shims to fill gap that is 1.5 centimeters wide. The width of three of the shims are 0.75 centimeter, 0.125 centimeter, and 0.1 centimeter. What is the width of the fourth shim
The width of the fourth shim used by a carpenter is, 0.525 centimeter.
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
The carpenter uses four shims to fill gap that is 1.5 centimeters wide.
And, The width of three of the shims are 0.75 centimeter, 0.125 centimeter, and 0.1 centimeter.
Now, Let the width of the fourth shim used by a carpenter = x
So, We can formulate;
⇒ x + 0.75 + 0.125 + 0.1 = 1.5
⇒ x + 0.975 = 1.5
⇒ x = 1.5 - 0.975
⇒ x = 0.525 centimeter

Graph the solution of |2x-1|=3 on the number line.
The graph of the solutions of the absolute value equation can be seen on the image at the end.
How to graph the solution of the equation?Here we have the absolute value equation:
|2x - 1| = 3
We can "break" that absolute value equation into two simpler ones, we will get:
(2x - 1) = 3
(2x - 1) = -3
Now we can solve these two, we will get for the first one.
2x - 1 = 3
2x = 3 + 1
x = 4/2
x = 2
The other gives.
2x - 1 = -3
2x = -3 + 1
2x = -2
x = -2/2 = -1
The solutions are 2 and -1, then the graph is the one below.

The earth is approximately 93,000,000 miles from the sun how long does it take from the Sun to reach the earth use the speed of light to be 1.86×10^5 Miles per second
The light from the sun takes 8 minutes 20 seconds to reach the earth.
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: The distance is 93,000,000 miles and the speed of light as 1.86×10⁵ miles per hour.
Now we know speed = Distance/ time
Thus we have Time taken = 93000000/1.86×10⁵

Therefore , the solution of the given problem of inequality comes out to be x=-3 or x<-3.
Define inequality.In mathematics, an inequality is a linking of two equations or numbers when there isn't an equal sign. Unbalance therefore precedes inequity. When two numerical values are not equal, an inequality results in a relationship between them. Egality and inequality are not the same. Where variables are not similar or equal, have used the most common symbol (). There are various inequalities that can be utilized to contrast values regardless of how small or huge they are. Switching the two sides it until variables represent all that is left can address a variety of basic inequality problems. The combination or division with low values from both sides are only a few examples of the many factors that might cause inequality. You switch sides and the left.
