how do do the work for 12c+6c=36
Answer:
c = 2
Step-by-step explanation:
To solve this equation, you need to combine like terms and then divide by the coefficient of the variable on both sides of the equation.
To start, add 12c and 6c because they are like terms.
12c + 6c = 18c
Then, divide by 18 on both sides of the equation to solve for c.
18c = 36

There are five consecutive odd integers. The sum of the three smallest is 3 more than the sum of the two largest. Find the integers.
Answer:
The answer is "[tex]\bold{11, \ 13, \ 15, \ 17, \ 19}[/tex]".
Step-by-step explanation:
In word problem, it is solved by 2k+1, among the most common forms of even an, unlike number.
Let another odd integer become 2k+1.....(a)
(2K+1)+(2k+3)+(2k+5)=(2k+7)+(2k+9)+3(to take the left side 3 extra)
Quality for the k:
[tex]\to 6k+ 9 = 4k +19 \\\\\ \to 6k-4k= 19+9 \\\\ \to 2k = 10 \\\\ \to k = \frac{10}{2}\\\\ \to K = 5[/tex]
put the value of k, in the equation (a):
[tex]\to 2k+1 \\ \to 2(5)+ 1 \\ \to 10 + 1\\\to 11\\[/tex]

You and Anthony are having a swimming race. You can swim 4 meters per minute, and Anthony can swim 4.5 meters per minute. You start at the same time. After how many minutes will Anthony be ahead of you 2 meters?
Answer:
4 minutes
Step-by-step explanation:
Given that:
Person 1's speed = 4 meters per minute
Anthony's speed = 4.5 meters per minute
To find:
In how many minutes, Anthony will be 2 meters ahead ?
Solution:
Let the time taken = [tex]t[/tex] minutes
Distance covered by 1st person = D meters
Distance covered by Anthony = (D + 2) meters
Formula:
Distance = Speed [tex]\times[/tex] Time
For 1st person:
[tex]D = 4 \times t[/tex] ....... (1)
For Anthony:
[tex]D+2 = 4.5 \times t[/tex]
Using first equation:
[tex]4t + 2 = 4.5t\\\Rightarrow 0.5t = 2\\\Rightarrow \bold{t = 4\ minutes}[/tex]
So, in 4 minutes, Anthony will be 2 meters ahead of the first person.

A. Area of the circle
B. Area of the rectangle
C. Calculate the area of the shaded region.
A. To find the area of a circle you need to use the formula A= π r²
The radius (R) is half of the diameter . . . that's 6.5 cm .
r² = ( 6.5)² = 42.25 cm²
Area = π r² = 42.25 π = 132.7 cm²
B. Area of a rectangle is just (length) x (width).
Length = 12 cm
Width = 5 cm
Area = (12 cm) x (5 cm) = 60 cm²
C. The shaded portion is the part of the circle that's NOT in the rectangle. So its area is (area of the circle) - (area of the rectangle)
Area = (132.7 cm²) - (60 cm²) = 72.7 cm²

Answer;
m<EAD=29°
m<CAB=119°
Step-by-step explanation:
Angles on a straight line sum up to 180°
This implies that,
61°+90°+EAD=180°
151°+EAD=180°
Subtracting 151° from both sides,we obtain,
EAD=180°-151°
EAD=29°
Angles on a straight line add up to 180°.
this implies that,
CAB+61°=180°
Subtracting 61° from both sides,we obtain
CAB=180°-61°
CAB=119°
Thus,m<EAD=29° and m<CAB=119°
Answer:
29° and 119°
Step-by-step explanation:
Since CF is a straight line, then
90° + ∠ EAD + 61° = 180°, that is
∠ EAD + 151° = 180° ( subtract 151° from both sides )
∠ EAD = 29°
and
∠ CAB + 61° = 180° ( subtract 61° from both sides )
∠ CAB = 119°

f(x)= 1 / x-3 g(x)= 3x + 1/x A. Use composition to prove whether or not the functions are inverses of each other. B. Express the domain of the compositions using interval notation. Please answer this worth 20 points
Step-by-step explanation:
(A) To find inverse of f(x) = y = 1 / x - 3 :
Transform in terms of x
y = 1 / x - 3
x - 3 = 1 / y
x = 3 + 1 / y
Exchange x with y :
[tex] {f}^{ - 1} (x) = 3 + \frac{1}{x} [/tex]
Therefore, g(x) is not inverse of f(x) and vice versa.
(B)
Domain of f(x) = R - {3}
Domain of g(x) = R - {0}

======================================================
Explanation:
The given equation is y = (-3/4)x - 2. Comparing it to y = mx+b, the slope is m = -3/4
Flip the fraction and the sign to go from -3/4 to 4/3. This is the perpendicular slope. Multiplying the two slopes gets (-3/4)*(4/3) = -1.
Rule: the original slope and perpendicular slope always multiply to -1, assuming neither line is vertical or horizontal.
We'll use the point (x,y) = (3,6) and the perpendicular slope m = 4/3 to find the y intercept b
y = mx+b
6 = (4/3)(3) + b
6 = 4+b
6-4 = b
2 = b
b = 2
The y = mx+b equation becomes y = (4/3)x + 2 which is the slope intercept form of the perpendicular line.
--------------
Extra info:
If you want to convert to standard form Ax+By = C, then you could do the following steps
y = (4/3)x + 2
3y = 4x + 6 ... multiply everything by 3 to clear out the fraction
3y - 4x = 6
-4x + 3y = 6
4x - 3y = -6 ... multiplying both sides by -1; this is to make A > 0

Jeff and Cameron are arguing about which one of them is faster. Jeff says "I can run 777 kilometers per hour!" and Cameron says "I can run 100100100 meters per minute!"
Answer:
Jeff is faster
Step-by-step explanation:
kilometers are faster than meters
and 7 kilometers is 700 meters
so 100 meters isn't fast enough compared to Jeff's speed
Jeff is faster than Cameron as his average speed is more than that of Cameron's average speed.
How to calculate the average speed of a body?The average speed of a body is the ratio of the distance covered by the body to the time it takes to cover that distance.
How to solve the given question?In the question, we are given that Jeff says that he can run 7 kilometers per hour while Cameron says that he can run 100 meters per minute.
We are asked to tell who is the faster among them.
We need to know that, 1 kilometer = 1000 meters, and 1 hour = 60 minutes.
Jeff's average speed = 7 km/hr. = 7km/1hr = (7*1000) m / (1*60) min
or, Jeff's average speed = 7000/60 meters per minute = 116.67 meters per minute.
We are given that Cameron's average speed is 100 meters per minute.
So, we can say that Jeff is faster than Cameron, as
Jeff's average speed > Cameron's average speed.
∴ Jeff is faster than Cameron as his average speed is more than that of Cameron's average speed.
