What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that three is less than the product of 2 and a number is equal to 5. The unknown number will be calculated as:-
2x - 3 = 5
2x = 5 + 3
2x = 8
x = 8 / 2 = 4
Therefore, the unknown number will be equal to 4.

Find the value of x that makes m parallel to n.
Find the derivative:
f(x)=tan(x^2+5)
Answer:
[tex]f'(x)=2x \sec^2(x^2+5)[/tex]
Step-by-step explanation:
To differentiate this we will need to use the chain rule:
[tex][h(g(x))]'=g'(x) \cdot h'(g(x))[/tex].
We will also have to keep in mind how to differentiate the following:
[tex]\tan(\theta)[/tex] with repect to [tex]\theta[/tex]
[tex]x^2+5[/tex] with respect to [tex]x[/tex].
[tex]f(x)=\tan(x^2+5)[/tex]
Derivative of both sides:
[tex]f'(x)=(x^2+5)'\cdot (\tan)'(x^2+5)[/tex]
[tex]f'(x)=(2x+0) \cdot \sec^2(x^2+5)[/tex]
[tex]f'(x)=2x \sec^2(x^2+5)[/tex]
Make t the subject of the formula
t = (3m -1) / (m - 1)
What is subject of formula?The subject of a formula is the variable that is being worked out. It can be recognized as the letter on its own on one side of the equals sign.
In order to change the subject of a formula, or rearrange a formula, items in the formula need to be rearranged so a different variable is the subject. Knowledge of solving equations and inverse operations is very useful.
Given formula.
m = t + 1 / t - 3
m ( t - 3) = t - 1
mt - 3m = t - 1
mt - t = 3m - 1
t(m - 1) = (3m - 1)
t = (3m -1) / (m - 1)
Hence, the formula becomes t = (3m -1) / (m - 1).

(SAT Prep) In the figure, what is the value of y?
A. 20°
B. 90°
C. 40°
D. 30°
Answer:
60 degrees
I checked in the RSM system
The value of angle y is C. 40°.
Using Straight angle property we can solve this question.
First we'll find the value of x using the straight angle property:
x+ 0.5x + 3x = 180°
4.5x = 180°
x = 180°/4.5
x = 40°
Now using vertically opposite angles property we get:
0.5x = 0.5y
0.5* 40° = 0.5y
20° = 0.5y
y = 20/0.5
y = 40°
Therefore, the value of y is 40°.

The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14. Find the number
Answer:
Required numbers are x = -0.5 and y =18.6
Step-by-step explanation:
Let the two numbers be x and y
Their sum is 18 i.e x+y= 18
4/7y-5x= 14
We need to find the numbers x and y
Solving both equations to find value of x and y
[tex]x+y= 18 ----(1)\\\frac{4}{7} y-5x= 14 ------(2)[/tex]
From equation 1 we can find value of x and put in equation 2 i.e
x=18-y
Putting the value of x in equation 2
[tex]\frac{4}{7}y-5(18-y)=14\\Solving:\\\\\frac{4}{7}y-90+5y=14\\\frac{4y-90*7+5*7y}{7}=14\\ \frac{4y-630+35y}{7}=14\\4y+35y-630=14*7\\39y=98+630\\y=728/39\\y=18.6[/tex]
Now finding x
[tex]x=18-y\\x=18-18.6\\x=-0.5[/tex]
So, Required numbers are x = -0.5 and y =18.6

The linear function or equation in the slope-intercept form will be y = -4x - 5.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
The linear function is given as,
y = mx + c
Here, m is the slope while c is the y-intercept.
Slope m = (-13 + 9)/(2 - 1)
m = -4
Put m = -4, (1,-9)
-9 = -4(1) + c
c = -5
y = -4x - 5
Hence "The linear function or equation in the slope-intercept form will be y = -4x - 5".

1/2(4x-2)=6x-13
Answer:
x=3
Step-by-step explanation:
How to solve your question
Your question is 1/2(4x-2)=6x-3
Solve
1.Combine multiplied terms into a single fraction
1/2(4x-2)=6x-13
1(4x-2) divided by 2 =6x-13
2.Multiply by 1
3 Subtract 6x from both sides of the equation
4.Simplify
5.Multiply all terms by the same value to eliminate fraction denominators
6.simplify
7.Add 2 to both side of equation
8.Simplify
9.Divide both sides of the equation by the same term
10.Simplify
Step-by-step explanation:
Combine multiplied terms into a single fraction
1/2 (4x-2) / 2 = 6x - 13
1 (4x -2) /2 = 6x -13
Multiply by 1
1 (4x - 2) / 2 = 6x - 2
4x - 2 / 2 = 6x-13
Subtract 6x from both sides of the equation
4x - 2 / 2 = 6x - 3
4x - 2 /2 - 6x =6x -13 -6x
Simplify
Combine like terms
4x -2 /2 -6x = -13
Multiply all terms by the same value to eliminate fraction denominators
4x -2 /2 -6x = -13
2 (4x-2 /2 -6x) =2(-13)
Simplify
Distribute
Cancel multiplied terms that are in the denominator
Combine like terms
Multiply the numbers
-8x -2 = -26
Add 2 to both sides of the equation
-8x -2= -26
-8x -2+2 = -26+2
Simplify
Add the numbers
Add the numbers
-8x = -24
Divide both sides of the equation by the same term
-8x = -24
-8x / -8 = -24 / -8

Betty is baking cakes to sell slices in her bakery. Each cake has 8 slices. She carefully adds an icing design, using 1/3 cup of icing for each slice. If she plans to bake 4 1/2 cakes, how many cups of icing will she use?
Answer: 12 cups
Step-by-step explanation:
Number of slices in a cake = 8 slices
Number of cups of icing used by each slice = 1/3
Number of cups of icing for each cake will then be:
= 1/3 × 8
= 8/3
= 2 2/3 cups of icing
If she plans to bake 4 1/2 cakes, the number of cups of icing will she use will be:
= 4 1/2 × 2 2/3
= 9/2 × 8/3
= 72/6
= 12 cups of icing
