The first operation that should be done first in the expression 5x + 3 = 28 is subtracting 3 from both sides.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, 5x + 3 = 28.
The first operation that should be done first is subtracting 3 to both the side of the equation to separate the variable x and the constant term.
∴ 5x + 3 - 3 = 28 - 3.
5x = 25.
x = 5.

What is the slope of a line perpendicular to the line whose equation is 4x – y = 9
Answers
Answer:
- [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
4x - y = 9 ( subtract 4x from both sides )
- y = - 4x + 9 ( multiply through by - 1 )
y = 4x - 9 ← in slope- intercept form
with slope m = 4
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{4}[/tex]
The sum of two numbers is 65 and the difference of those two numbers is -18
Answers
Answer:
41.5
23.5
Step-by-step explanation:
Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 65. In other words, x plus y equals 65 and can be written as equation A:
x + y = 65
The difference between x and y is -18. In other words, x minus y equals -18 and can be written as equation B:
x - y = -18
Now solve equation B for x to get the revised equation B:
x = -18 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 65
-18+y+y=65
-18 + 2y = 65
2y = 83
y = 41.5
Now we know y is 41.5. Which means that we can substitute y for 41.5 in equation A and solve for x:
x + y = 65
x + 41.5= 65
X = 23.5
DIfference : 23.5 - 41.5 = 18
Sum: 41.5 +23.5 = 65
Hence, The two number are 23.5 and 41.5

What value for a would make the equation true? Type in only the numerical answer or value.
Answers
Answer:
a = 3
Step-by-step explanation:
Here you can use the cross multiplication strategy or whatever it's called. That's where you multiply the diagonals together. Its kinda long to explain, but you can google it for details.
In either case, you get the following equation:
8(2a-1) = 4(a+7)
Open the parenthesis
16a - 8 = 4a + 28
Subtract 4a from both sides
12a - 8 = 28
Add 8 to both sides
12a = 36
Divide both sides by 12
a = 3

This uses the cosine Law for line length.
Formula
a^2 = b^2 + c^2 - 2*b*c*sin(A)
Givens
a = 5
b = 7
c = 10
Solution
5^2 = 7^2 + 10^2 - 2*7*10*cos(A)
25 = 49 + 100 - 140*cos(A) Combine the right side
25 = 149 - 140 * cos(A) Subtract 149 from both sides
25 - 149 = - 140*cos(A)
-124 = -140 * cos(A) Divide both sides by -140
-124/-140 = cos(A)
Cos(A) = 0.8857 Take the inverse Cos of both sides
A = cos-1(0.8857)
Answer
A = 27.66 degrees
