The LCM of 12 and 15 is 60. To find the least common multiple (LCM) of 12 and 15, we need to find the multiples of 12 and 15 (multiples of 12 = 12, 24, 36, 48 . . . . 60; multiples of 15 = 15, 30, 45, 60) and choose the smallest multiple that is exactly divisible by 12 and 15, i.e., 60.

Answers
Answer: To find Usain's speed in miles per hour, we need to convert the distance from yards to miles and the time from seconds to hours. To convert yards to miles, we divide the number of yards by the number of yards in a mile (1,760). To convert seconds to hours, we divide the number of seconds by the number of seconds in an hour (3,600).
So, to find Usain's speed, we use the formula:
Speed = Distance / Time
In this case, we have:
Speed = (100 yd) / (9 s)
We need to convert yards to miles and seconds to hours, so we can use the following conversion factors:
1 yd = 1/1,760 mi
1 s = 1/3,600 hr
By applying this conversion factor we get the speed in miles/hour.
Speed = (100 yd) / (9 s) * (1/1,760 mi/yd) * (1/3,600 hr/s)
So the final answer will be:
Speed = (100/9) * (1/1,760) * (1/3,600) miles/hour
Hence, option M: 3,600 s is the final answer.

Kayla is 3/4 of the way from New York to Boston. She began with 4/5 of a full tank of gas. She has 1/5` of a tank of gas left. Does she have enough gas to reach Boston?
Answers
Yes, Kayla has enough gas to reach her destination which is Boston.
What is ratios?Ratios can be defined as the expression that shows the relationship between two variables that are of the same unit.
The present location of Kayla = 3/4 of the way to new York.
The remaining distance = 1/4
The quantity of fuel that took her to that present location = 4/5 of full tanks
Therefore if 3/4 distance = 4/5 fuel
1/4 distance = 1/5 fuel
It can be concluded that Kayla has enough gas to reach her destination which is Boston.

The graph of the solutions of the absolute value equation can be seen on the image at the end.
How to graph the solution of the equation?Here we have the absolute value equation:

We can "break" that absolute value equation into two simpler ones, we will get:
(2x - 1) = 3
(2x - 1) = -3
Now we can solve these two, we will get for the first one.
2x - 1 = 3
2x = 3 + 1
x = 4/2
x = 2

Answers
Answer:

Step-by-step explanation:
Let x and y be the two natural numbers
x - y > 6 and x - y < 11
6 < x - y < 11
x is still positive after y amount is taken away from it. Since y is part of x, x is the greater value.
Hence, x=14:
6 < 14 - y < 11 ==> solve for y, the missing value
-8 < -y < -3 ==> subtract 14 on all sides

The inequality's sign will indicate which half-plane to shade, unless you are graphing a vertical line. Shade above the line if either the or > symbol is present. Shade below the line if the symbol "or" is used. When a linear inequality contains the symbols "less than" or "less than or equal to," you should shade below the boundary line. In a linear inequality, you will shade above the boundary line if the symbol is > (greater than) or (greater than or equal to).

Answers
The light from the sun takes 8 minutes 20 seconds to reach the earth.
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: The distance is 93,000,000 miles and the speed of light as 1.86×10⁵ miles per hour.
Now we know speed = Distance/ time
Thus we have Time taken = 93000000/1.86×10⁵
= 8 minutes 20 second (approx)

Answers
To solve the equation 2c - 3 = 2(6 - c) + 7c, option 1: Distribute and collect like terms on each side is done.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
The given equation is 2c−3=2(6−c)+ 7c.
To solve the equation first use the distributive property to multiply 2 by 6-c.
2c - 3 = 12 - 2c + 7c
Next, combine the like terms -2c and 7c to get 5c.
2c - 3 = 12 + 5c
Now, subtract 5c from both left-hand side and right-hand side.
2c - 3 - 5c = 12 - 5c
Next, combine the like terms 2c and -5c to get -3c.
- 3 - 3c = 12
Now, add 3 to both left-hand side and right-hand side.
- 3 - 3c + 3 = 12 + 3
Next, on right-hand side add 12 and 3 to get 15.
- 3c = 15
Now, divide both left-hand side and right-hand side by -3.
(-3c)/-3 = 15/-3
The result is obtained as -
c = -5
Therefore, the solution for the equation is c = -5.

Step-by-step explanation:
Area - number of units inside a given shape (Your using this one)
Perimeter - number of units to cover the outside
Step 1: Determine the needed formulas. In this case, there are 2 rectangles, so we will use Width X Height to solve
Step 2: Break the shape into simple shapes to solve
Step 3: Solve
Solving purple rectangle: 8 is the width, and the height is 2
8 x 2 = 16
Solving pink rectangle: 4 is the height, and 5 is the width
4 x 5 = 20
Step 4: Once all areas are found, add them together
16 + 20 = 36 36 is the total Area
_______________________________________________________
Problem 2
Again there are 2 rectangles, so we will use Width X Height to solve
Step 2: Break the shape apart
Step 3: Solve
Solving blue rectangle: 2 is the width, 3 is the height
2 x 3 = 6
Solving green rectangle: 7 is the width, 3 is the height
7 x 3 = 21
Step 4: Add
6 + 21 = 27 27 is the total Area
* Remember, Every shape has a given formula to find the area*
Here are some that you will need for the worksheet:
-The formula for finding the area of a rectangle is length x width.
-The formula for finding the area of a square is side x side.
