the difference of twelve and three times a number and negative 4
Answer:The answer is going to be 3 and this is how we came to that determination:
We are to subtract 3 times the number from 7 times the number and have it equal 12. So here is the the mathematical sentence to help us get the answer:
7X-3X=12 ; now we are going to subtract the 3 from the 7 on the left hand side of the equal sign:
4X=12 ; now we will divide each side of the equal sign by 4:
4X/4=12/4 and get X =3 ; to prove 3 is the number we are looking for, we will substitute it for X in our original sentence:
7(3)-3(3)=12
21–9=12
12=12
3 is our answer.

Carson draws a scale drawing of a city park and a parking lot. The city park is in the shape of a right triangle with logs that are 3 inches and 4 inches. The parking lot is in a shape of a rectangle with
dimensions of 15 inches and 25 inches. The scale for the drawing is 1 inch 40 feet.
Answer:
6,000 & 19,200
What is the area of the rectangle?
Answer:
Area = 396 units²
Step-by-step explanation:
Let's assume:
Length = 2c - 5
Width = 5c + 9
Perimeter = 2(L + W) = 106 units
Thus:
2[(2c - 5) + (5c + 9)] = 106
Find the value of c
2[2c - 5 + 5c + 9] = 106
2[7c + 4] = 106
14c + 8 = 106
14c = 106 - 8
14c = 98
Divide both sides by 14
c = 98/14
c = 7
✔️Area of the rectangle = Length × Width
Area = (2c - 5)(5c + 9)
Plug in the value of c
Area = (2×7 - 5)(5×7 + 9)
Area = (14 - 5)(35 + 9)
Area = (9)(44)
Area = 396 units²

The value of P for the given angles of the quadrilaterals is 6.
What is geometry?One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that the two opposite angles are 4P + 12 and 36 respectively.
The value of P for the two opposite angles will be calculated as:-
4P + 12 = 36
4P = 36 - 12
4P = 24
P = 24 / 4
P = 6
Hence, the value of P for the given angles of the quadrilaterals is 6.

solve 4(x+7)-5x+2=10
Answer:
x = 20
Step-by-step explanation:
4(x + 7) - 5x + 2 = 10
open the parenthesis
4 * x + 4 * 7 - 5x + 2 = 10
4x + 28 - 5x + 2 = 10
combine like terms
-x + 30 = 10
subtract 30 from both sides of the equation
-x + 30 - 30 = 10 - 30
-x = 10 - 30
-x = -20
mutiply the equation by -1
-1 * -x = -20 * -1
x = 20
It takes Sara 5 1/2hours to drive to her aunt's
house. She has already driven 3 1/2 hours.
How much longer does Sara have left to
drive?
Answer:
2 hours
Step-by-step explanation:
To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:
5.5 - 3.5 = 2.0
Meaning, Sara has 2 hours left to drive

Under her cell phone plan, Autumn pays a flat cost of $48 per month and $5 per gigabyte. She wants to keep her bill at $68.50 per month. Write and solve an equation which can be used to determine gg, the number of gigabytes of data Autumn can use while staying within her budget.
Answer:
Equation: 68.50=48+5x Answer: 4gigabytes
Step-by-step explanation:
You have to add the flat cost and the cost per gigabyte together. Then set it equal to her maximum amount and solve.
The equation to calculate the number of gigabytes will be 68.50=48+5x. The number of gigabytes will be 4.1 GB
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 under her cell phone plan, Autumn pays a flat cost of $48 per month and $5 per gigabyte. She wants to keep her bill at $68.50 per month.
The expression can be written as below:
68.50=48+5x
5x = 68.5 - 48
5x = 20.5
x = ( 20.5 / 5 ) = 4.1 Gb
Therefore, the equation to calculate the number of gigabytes will be 68.50=48+5x. The number of gigabytes will be 4.1 GB

A line passes through the point (2, 1) and has a slope of -5/2
Write an equation in slope-intercept form for this line.

Given

Determine the line equation
In slope intercept form, a line equation is:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - 1 = -\frac{5}{2}(x - 2)[/tex]

[tex]y = -\frac{5}{2}x +6[/tex]
Brandon rode in a taxi that charges a flat fee of $2.25 and an additional $0.40 per mile of his trip. If he paid $6.80 for the cab ride, how many miles did he travel? (HOW DID YOU GET YOUR ANSWER SHOW YOUR WORK!!)
A. 11 3/8
B. False
C. 1/5
D. 61.5
E. True
F. 3/25
G. 62.4
Answer:
11 [tex]\frac{3}{8}[/tex] miles.
Step-by-step explanation:
To find how many miles Brandon rode, we can create an equation in slope-intercept form: y = mx + b
$2.25 is the flat fee, or the unchanging variable. This is our y-intercept, or b.
$0.40 is the changing variable, as it changes value depending on the amount of miles ridden. This is our slope, or m.
We know Brandon spent $6.80 on the cab ride. So, this is our y.
We get the equation: 6.80 = 0.40x + 2.25.
To solve, first subtract 2.25 from both sides of the equation:
6.80 - 2.25 = 0.40x + 2.25 - 2.25
We get: 4.55 = 0.40x
Now, just divide by 0.40 on both sides:
4.55 ÷ 0.40 = 0.40x ÷ 0.40
We get: 11.375 = x
So, Brandon rode for 11.375 miles. When converted to a mixed number, we get 11 [tex]\frac{3}{8}[/tex] .
