2( 5y-2) + 2(4y+1) =124
Divide both sides with 2
5y - 2 + 4y + 1 = 62
9y - 1 = 62
9y = 63
y = 7
Plug in y for the equation of RS.
RS = 5y - 2
RS = 5(7) - 2

what is the length of each side of a regular hexagon?
Answers
Answer: s = P ÷ 6
Step-by-step explanation:
The simplest, and by far most common, way of finding the length of a regular hexagon's sides is using the following formula: s = P ÷ 6, where P is the perimeter of the hexagon, and s is the length of any one of its sides.
Answer:
All the interior angles measure 120°. All the exterior angles measure 60°. Since all angles are equal in a regular hexagon, each angle is 120o and the sum of all the interior angles is 720o.

The statements that are true regarding the measures of center and variability of these data sets include:
A. The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
C. The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
E. The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
How to calculate the mean of any data set?In Mathematics and Statistics, the mean for any set of data can be calculated by using the following formula:
Mean, \bar{x} = ∑x/n
Where:
∑x represents the sum of all data values.n represents the total number of data items.Based on the information provided, we have:
Mean of Yard Works = (7+9+7+12+5)/5
Mean of Yard Works = 8.
Mean of Grow Station = (9+11+6+12+7)/5
Mean of Grow Station = 9.
Range is the difference between the maximum and minimum numbers;
Range of Yard Works = 12 - 5
Range of Yard Works = 7.
Range of Grow Station = 12 - 6
Range of Grow Station = 6.
Mean absolute deviation is given by;
MAD = 1/n ∑|x - μ|
Where:
n represents the number of data (observed values)μ represents the mean of the data set.x represents the individual data (values)Mean absolute deviation of Yard Works = 2
Mean absolute deviation of Grow Station = 2.

The table below shows the ratio of materials in a composting container.
Brown Material (gallons) 12.75 18.6 24 E
Green Material (gallons) 4.25 B D 11.5
Total (gallons) A C 32 46
If Jeremy needs 64 gallons of compost to plant his garden in the spring, how much brown material will he need? How much green material will he need?
Jeremy will need 52 gallons of brown material and 12 gallons of green material.
Jeremy will need 16 gallons of brown material and 48 gallons of green material.
Jeremy will need 12 gallons of brown material and 52 gallons of green material.
Jeremy will need 48 gallons of brown material and 16 gallons of green material.
Answers
Using proportions, the amounts needed of brown and green material for 52 gallons of compost are given as follows:
Brown material: 39 gallons.
Green material: 13 gallons.
What is a proportion?A proportion is a fraction of a total amount, and in problems involving it, basic arithmetic operations such as multiplication or division are used along with the unit rates to find the equivalent measures.
On the first column of the table, the total amount is:
12.75 + 4.25 = 17 gallons.
The fractions of each material are given as follows:
Brown material: 12.75/17 = 0.75
Green material: 4.25/17 = 0.22.
Hence the amount of brown material needed with 52 gallons is:
0.75 x 52 = 39 gallons.
The amount of green material needed with 52 gallons is:
0.25 x 52 = 13 gallons.

But the sum of these side lengths does not add up to 180 degrees, therefore it's not possible to form a polygon with these side lengths.

Doug builds a skateboard ramp.The base is 6 feet long and the height is 1.5 feet.What is the slope of the ramp?Explain
Answers
Answer: The slope of the ramp is 0.25
Step-by-step explanation: The slope of a ramp is a measure of how steep it is. It is typically expressed as a ratio of the height to the length, also known as the rise over the run. To calculate the slope of the ramp, you can divide the height by the length.
In this case, the ramp is 6 feet long and 1.5 feet high, so the slope is:
1.5 feet / 6 feet = 0.25
So the slope of the ramp is 0.25, which can also be written as a fraction 1/4 or 25%. This means that for every four feet of horizontal distance, the ramp rises by one foot.
Alternatively, you can think of this as the angle of the ramp, if the angle formed by the ramp is small it will have a small slope and if the angle formed is large, it will have a large slope.
In simpler terms, the slope represents how steep the ramp is. The higher the slope, the steeper the ramp will be. And the lower the slope, the gentler the ramp will be. In this case, since the slope is 0.25 it is a gentle ramp.
Answer:
0.25

Add elements together:
= y + 3
Arrange equation so that like terms are next to each other
3.9y - 2.9y + 3
Subtract.
1y + 3
Since 1y and 3 are not like terms, we cannot add them.
Therefore, 1y + 3 is the answer.

4 tires = $319.96
1 tire =$b
cross multiplying,
4× b = 1 × 319.96

The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π.
Answers
Answer:
Step-by-step explanation:
A = πr^2
(153.86) = (3.14) r^2
Divide 3.14 on both sides.
49 = r^2
Square root both sides.
7 = r
D = 2r
D = 2(7)
D = 14
The diameter of the circle is 14 square meters.
Answer:
14 meters²
Step-by-step explanation:
Since the formula to find the diameter is d = 2r, we need to first find the radius, which can be r = square root of Aπ over π if we take the formula for the area of a circle and isolate the radius. After simplifying r = square root of 153.86π over π to 7 and multiplying that by 2, we get the circle's diameter of 14 meters. Hope this helps!
On the windowsill is a plant that is 8 inches tall. It is growing 2 inches per week. A second plant, which is 3 inches tall, is on the coffee table. It is growing 4 inches per week. Eventually the two plants will be the same height. How tall will the plants be?
Answers
Answer:
Let's call the height of the first plant as x and the height of the second plant as y.
We know that the first plant is 8 inches tall and growing 2 inches per week, so we can write the equation:
x = 8 + 2t (where t is the time in weeks)
We know that the second plant is 3 inches tall and growing 4 inches per week, so we can write the equation:
y = 3 + 4t
We also know that the two plants will be the same height when they meet, so we can set the two equations equal to each other:
x = y
8 + 2t = 3 + 4t
5 = 2t
t = 2.5
So the plants will be the same height in 2.5 weeks. To find out how tall they will be, we can plug this value of t back into either equation:
x = 8 + 2(2.5) = 8 + 5 = 13 inches
y = 3 + 4(2.5) = 3 + 10 = 13 inches
So both plants will be 13 inches tall when they reach the same height.

List the sample space for rolling a fair six-sided die. S = {1} S = {6} S = {1, 2, 3, 4, 5, 6} S = {1, 2, 3, 4, 5, 6, 7, 8}
Answers
Answer:
The sample space for rolling a fair six-sided die is: S = {1, 2, 3, 4, 5, 6}
The sample space represents all the possible outcomes of an event. In this case, the event is rolling a fair six-sided die, so the sample space is the set of all the possible numbers that can appear on the die, which are 1, 2, 3, 4, 5 and 6.
Option A, S = {1}, is incorrect because this only represents one outcome, not all possible outcomes.
Option B, S = {6}, is incorrect because this only represents one outcome, not all possible outcomes.
Option C, S = {1, 2, 3, 4, 5, 6}, is correct as it represents all possible outcomes.
Option D, S = {1, 2, 3, 4, 5, 6, 7, 8}, is incorrect because this includes numbers that cannot appear on a six-sided die, and it does not represent all possible outcomes.
