C+2c+12=75
what is the value of c?
Answers
3c+12=75
Subtract 12 from both sides
3c=75−12
Simplify 75−12 to 63
3c=63
Divide both sides by 3
c=63/3
Simplify 63/3 to 21
c=21
3c + 12 = 75
3c = 75 - 12
3c = 63
с = 63 : 3
с = 21
______________________
3 × 21 + 12 = 75
63 + 12 = 75
75 = 75

the answer is the option
B. f(n + 1) = f(n) + 0.75
It would be f(n+1) = f(n)+0.75

Answer:
y = 2x + 11
Step-by-step explanation:
Slope-intercept form (y=mx+b) of linear equations highlights the slope (m) and the y-intercept (b) of a line.
Slope = m = rise/run = (y2-y1)/(x2-x1) = (15-21)/(2-5) = -6/-3 = 2
substitute 2 back into the equation.
y = mx + b
y = 2x + b
use one of the provided points to solve for b.
y = 2x + b
15 = 2(2) + b
15 = 4 + b
11 = b
y = 2x + 11

Hey!
The area of the board is 60,000 centimeters.
1 meter = 100 centimeters
2 meters = 200 centimeters
3 meters = 300 centimeters
300 × 200 = 60,000
One cup covers 1,000 centimeters. To cover 60,000 centimeters, divide 60,000 by 1,000.
That means Arella needs 60 cups
Since the paint covers a certain number of square centimeters and the board's dimensions are given in meters, we need to use one single unit.
Let's convert the measurements in meters to centimeters and work with square centimeters.
The board measures 3 meters by 2 meters.
There are 100 cm in a meter.
3 m = 300 cm
2 m = 200 cm
area of rectangle = length * width
area of rectangle = 300 cm * 200 cm = 60,000 cm^2
The area of the rectangle is 60,000 cm^2
One cup covers 1,000 cm^2.
How many times the area of 1,000 cm^2 needs to be covered?
60,000 cm^2 is how many times 1,000 cm^2?
We use division to answer that question.
(60,000 cm^2)/(1,000 cm^2) = 60
60,000 cm^2 is 60 times 1,000 cm^2.
Since 1 cup covers 1000 cm^2, and Arella needs to cover 60 times that area, Arella needs 60 times the paint contained in 1 cup, so the answer is 60 cups.
Answer: Arella needs 60 cups of paint.
system of equations?
(1) (3,0) is the solution to the system because it satisfies the equation
y = |x - 3|.
(2) (9,0) is the solution to the system because it satisfies the equation
3x + 3y = 27.
(3) (6,3) is the solution to the system because it satisfies both equations.
(4) (3,0), (9,0), and (6,3) are the solutions to the system of equations
because they all satisfy at least one of the equations.
Answers
3x + 3y = 27
3x + 3|x - 3| = 27
3x + 3|x - 3| = ±27
3x + 3|x - 3| = 27 or 3x + 3|x - 3| = -27
3x + 3(x - 3) = 27 or 3x + 3(x - 3) = -27
3x + 3(x) - 3(3) = 27 or 3x + 3(x) - 3(3) = -27
3x + 3x - 9 = 27 or 3x + 3x - 9 = -27
6x - 9 = 27 or 6x - 9 = -27
+ 9 + 9 + 9 + 9
6x = 36 or 6x = -18
6 6 6 6
x = 6 or x = -3
y = |x - 3| or y = |x - 3|
y = |6 - 3| or y = |-3 - 3|
y = |3| or y = |-6|
y = 3 or y = 6
(x, y) = (6, 3) or (x, y) = (-3, 6)
The two systems of equations of the graph is only equal to (6, 3). It is not equal to (-3, 6) because one of the systems of equations - y = |x - 3| - only has one solution to the function. So the answer to the problem is 3 - (6, 3) is the solution to the system because it satisfies both equations.
