5x-28=-3
You want to isolate x.
First, add 28 to both sides to isolate 5x, what you do to one side you do to the other, so:
5x= 25
Seperate 5x by dividing it, so 25/5.
x = 5 is your answer.
a whole number larger than 2 leaves a remainder of 2 when divided by each of the numbers 3, 4, 5 and 6.
A whole number larger than 2 leaves a remainder of 2 when divided by each of the numbers 3, 4, 5, and 6 is 62.
What are whole numbers?Whole numbers are numbers without fractions and consist of positive integers and zero. It is represented by the symbol "W," and the numbers are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,...............Zero in its entirety represents nothing or a null value.To find the whole number:
LCM of 3, 4, 5, and 6 = 3 × 2 × 2 × 5 = 60Add the remainder 2 in 60: 60 + 2 = 62So, the whole number is 62.Therefore, a whole number larger than 2 leaves a remainder of 2 when divided by each of the numbers 3, 4, 5, and 6 is 62.

4. Juan has 28 paperback books that measure
re 1 1/4 inches each, how many books will fit on one
shelf if each shelf measures 30 inches?
Answer:
24 books can fit on 1 shelf.
Step-by-step explanation:
Question: Juan has 28 paperback books that measure 1 and 1/4 inches each. How many books will fit on one shelf if each shelf measures 30 inches?
Step-by-step:
We know that each book is 1 and 1/4 inches each. It might be easier to convert the fraction into a decimal.
1/4 inches is 1 divided by 4 which equals to 0.25 inches
1 inch + 0.25 inches = 1.25 inches
so, 1 and 1/4 inches = 1.25 inches
To find out how many books fit on a shelf, we need to find: length of 1 bookshelf divided by length of 1 book
We know that one bookshelf is 30 inches and 1 book is 1.25 inches
so, 30/1.25 or 30 divided by 1.25 = 24
Therefore, 24 books can fit on 1 shelf.
The gardening store sells clay flower pots, which hold 8 litres of dirt, and ceramic flower pots, which hold 9 litres. Billy bought 8 flower pots, which will hold a total of 67 litres of dirt. How many of each type of flower pot did he buy?
According to the given statement;
Billy bought 8 flower pots, which will hold a total of 67 litres of dirt. The flower pot Billy bought his flower pot is x=5.
What is one variable equation?The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For example, 2x+3=8 is a linear equation having a single variable in it.
What is a linear equation in math?A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.According to given value ;
Let x = number of clay pots. Since Billy bought 8 pots in total , the number of ceramic pots Billy bought is 8-x
67 =(8 litre )*(x clay pots)+(9 litres)*(8-x);
By solving one variable equation;67=8x+72-9x
67=(-x)+72
-x =(-72+67)
( -x) = -5
x =5
Hence 8 litre of dirt clay pots is 5 then 9 litres of ceramic flower pot is is 3.

Basically, the opposite 3 functions area unit usually used as compared to the first pure mathematics functions.
The diagram of the given question is given below .
Applying sin rule in triangle ABC , we get

sin(45°) = 4 / AB
1 /√2 = 4 / AB
AB = 4√2
AB ≈ 5.657
Similarly, apply sin rule in triangle ACD, we get
sin(y°) = AC /CD
sin(63°) = 4 / CD
AD = 4.489
Now distinction in lengths of AB and AD = 5.657 - 4.489

For the function h defined as h(x) = nx² + 28, n is a constant and h(3) = 1. What is the value of h(-6) ?
Answer:
Step-by-step explanation:
Step One
The first step is to find the value of n.
h(x) = n(x) + 28
h(3) = 1
That means that 1 is on the left and wherever there is an x on the right, it will have a value of 3
Step Two
Substitute values
1 = n(3) + 28
Step 3
Solve
1 = 3*n + 28 Subtract 28 from both sides
1 + - 28 = 3n Combine
-27 = 3n Divide both sides by 3
-27/3 = 3n/3
- 9 = n
Step 4
Let x = - 6 on the right side of the original equation.
h(-6) = 3*-6 + 28
h(-6) = -18 + 28
Answer
h(-6) = 10

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is worth either 5 points or 2 points. Write a system of equations that can be used to find how many problems of each point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
Answer:
There are 14 problems worth 5 points and 15 problems worth 2 points.
Step-by-step explanation:
x - the number of 5 points worth problems
y - the number of 2 points worth problems
The test has 29 problems.
x+y=29x+y=29
The test is worth 100 points.

The system of equations:
x+y=29
5x+2y=100
The solution:
x+y=29 ∣×(−2)
5x+2y=100
Substract −2x−2y=−58 from 5x+2y=100
−2x−2y=−58
5x+2y=100
------------------
3x=42
3x/3 = 42/3
x=14
x+y=29

7) In the given figure, PQR is an equilateral triangle with coordinates of Q and
R as (-2, 0) and (2, 0) respectively. Find the coordinates of the vertex P.
The coordinates of the vertex P is calculated as (0,2√3).
What is defined as the distance formula?The distances among two points as a characteristic of their coordinates are given by an algebraic expression (like coordinate system).
The Pythagorean theorem is used to derive distance formulae for points in rectangular coordinates in 2- and three-dimensional Euclidean space.Because it has a starting and ending point, a line segment can be graphed in both two-dimensional and three-dimensional coordinate planes.Because of the two-dimensional coordinate plane, the starting and stopping points can also be marked as two-dimensional coordinates (x₁, y₁) and (x₂, y₂), culminating in the distance formula as: d = √(x₂ - x₁)² + (y₂ - y₁)².Now, according to the given question;
The coordinates of the points Q and R is given as;
Q and R as (-2, 0) and (2, 0).
Now, as the all three points P,Q and R forms the equilateral triangle. Then, the distance of each side or the distance between two consecutive points are equal.
Calculate the distances between the points;
Distance between Q and R;QR = √(2 + 2)² + (0 - 0)²
QR = 4
Distance between Q and P;Let the coordinated of P be (x, y);
Then,
QP = √(x + 2)² + (y + 0)²
QP = QR = 4
4 = √(x + 2)² + (y)² ........(equation 1)
Distance between R and P;RP = √(x - 2)² + (y + 0)²
RP = QR = 4
4 = √(x - 2)² + (y)² ........(equation 2)
Equating equation 1 and 2.
√(x + 2)² + (y)² = √(x - 2)² + (y)²
Squaring both side;
(x + 2)² + (y)² = (x - 2)² + (y)²
x² + 4 - 4x + y² = x² + 4 - 4x + y²
Simplifying the equation;
x = 0.
Put the value of x in equation 1;
4 = √(x + 2)² + (y)²
y = 2√3.
Therefore, the coordinates of the point P are found to be (0, 2√3).

This indicates that there aren't any discontinuities or sudden changes in value. In other words, a function is continuous if and only if its graph is devoid of any gaps or breaks. It is simple to predict where it won't be continuous for many functions. Where we have operations like division by zero or logarithms of zero, functions won't be continuous.

Explain the properties used to solve inequalities and how they are different from properties of equality
The major difference between inequality and equality is that equality represents a particular value(s) while inequality represents a range of values that are in a specific direction.
What are the properties that are used to solve inequalities?This must be noted when solving questions on equality and inequality.
For example:
x = a means that the value of x is a. It represents a particular value which is a
x < a represents all the values that are less than a.
x ≤ a represents values from a and below.
x > a represents all the values that are greater than a
x ≥ a means that the values of x are greater than or equal to a.
From the examples given above, it is obvious that a change in the direction of the inequality sign changes the values of the data represented by the inequality.
