Answer:
216
Step-by-step explanation:
I'm sure there is a simpler way to do this but this is how I did it.
First divide 18 by 6 because it triples every 6 hours.
18/6=3
This means it will triple three times
Then triple the value three times
#1. 8x3=24
#2. 24x3=72
#3. 72x3=216

URGENT need answer quick
Answer:
Part A: x = 4.
Part B: The answer normally would be x = 12, but since your question asked why it has no real solution, it is because the solution (x=12) does not make the equaion true. Why? Because the value given from the equation that should make the equation true does not relate the equation in itself; hence making it have no solution.

Solve the system using substitution.
2x = 5y + 14
x = 5y
Answer:
y = 2.8x = 14Step-by-step explanation:
To solve an equation, we can only have one variable. In this case, we are given the system 2x = 5y + 14. However, we are given the value of x in terms of y. We can substitute 10y in for 2x and solve.
10y = 5y + 14
First, we need to get all the variables on one side of the equation, so we subtract 5y.
5y = 14
Divide by 5
y = 14/5 or 2 4/5 or 2.8
Now for the x part.
2x = x + 14
Subtract 1x
x = 14
Now we check our answer.
2(14) = 5(2.8) + 14
28 = 14 + 14
28 = 28
Because 28 equals 28, our solutions are correct.

Compare a dilation to the other transformations:
translation, reflection, rotation.
Answer:
A translation simply moves the graph, or pre-image, without changing the size or spinning the image. A reflection flips the pre-image across some line. A rotation spins the pre-image around a point. A dilation either expands or shrinks the pre-image.
Step-by-step explanation:
Hope this helps
Transformation involves changing the size, the position and the location of a shape.
DilationWhen a shape is dilated, the size of the shape is altered to form a new shape
Translation
When a shape is translated, the shape is moved across the coordinates, but the size remains unchanged
ReflectionWhen a shape is reflected, the shape is flipped across the coordinates, but the size remains unchanged
RotationWhen a shape is rotated, it must be rotated across a point, and the size remains unchanged
The above means that translation, reflection and rotation are rigid transformation, while dilation is not.

Find the value of x.

X =
Answer:
x = 18
Step-by-step explanation:
The inner and outer triangles are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{80}{80+2x}[/tex] = [tex]\frac{60}{60+27}[/tex] = [tex]\frac{60}{87}[/tex] ( cross- multiply )
60(80 + 2x) = 6960 ← divide both sides by 60
80 + 2x = 116 ( subtract 80 from both sides )
2x = 36 ( divide both sides by 2 )
x = 18
A school has 1,200 concert tickets for sale. Some of the
tickets are for reserved seats (r), and the rest are for general
admission (g). At most, 500 reserved-seat tickets can be
sold. Which pair of inequalities models the number of
tickets that can be sold?
Answer: d
Step-by-step explanation:
r+g less than or equal to 1,200
r less than or equal to 500
The pair of inequalities models the number of tickets that can be sold is r + g ≤ 1200 and r ≤ 500
Let r represent the number of reserved seats and g represent the number of seats for general admission.
Since the school has 1,200 concert tickets for sale, hence:
r + g ≤ 1200 (1)
Also, there are at most 500 reserved-seat tickets. Hence:
r ≤ 500 (2)
The pair of inequalities models the number of tickets that can be sold is r + g ≤ 1200 and r ≤ 500

Answer:
3.5
Step-by-step explanation:
The constant rate of proportionality, k, is expressed as [tex]k = \frac{y}{x}[/tex], and shows that two quantities are proportional to each other. In this logic, rearranging this in terms of y gives us:
[tex]y = kx[/tex]
Thus we can determine that k is 3.5, in this case.

Emma bought a sweater that was 20% off. She paid $36 for the sweater, What was the original cost of the sweater?
Please hurry!
Answer:
$45
Step-by-step explanation:
let's work backwards. We know that it was 20% off, or otherwise 80% of the original cost. Let's represent the original cost with x:
0.8x = 36
Now we solve for x by dividing both sides by 0.8:
x = 45
Thus, the sweater was originally $45

Explain how you would distribute 4 ones into 5 groups.m
The number of ways he can distribute 4 ones into 5 groups is 120 ways.
PermutationPermutation has to do with the arrangement. For instance, to distribute "r" values into "n" groups, this can be calculated as:
nPr = n!/(n-r)!Hence for you to distribute 4 ones into 5 groups, we will use the formula above to have:
5P4 = 5!/(5-4)!
5P4 = 5!/1!
5P4 = 5!
5P4 =120 ways
Hence the number of ways he can distribute 4 ones into 5 groups is 120 ways.

Answer:
x=-5
Step-by-step explanation
The first box has eight x's and six 1's which means that it would be written as 8x+6
The second box has four x's and fourteen -1's which means that it would be written as 4x-14
You set them equal to one another
8x+6=4x-14
You subtract 4x from both sides
4x+6=-14
Subtract 6 on both sides
4x=-20
Divide 4 on both sides
x=-5

Find the value of x. Sum 1 help I rlly don’t get this
Answer:
x = 12 degrees
Step-by-step explanation:
This isosceles triangle has two equal sides and thus two equal angles. We find the measure of angle 2 by subtracting 76 degrees from 180 degrees, and then dividing the result (104 degrees) by 2: m<2 = 52 degrees.
Then m<2 = 52 degrees = 3x + 16, or
52 degrees - 16 degrees = 3x, or:
36 degrees = 3x
Thus, x = 12 degrees
tire rim has a diameter of 15 in. What is the circumference of the tire rim? Use 3.14 for Pi.
23.55 in.
46.10 in.
47.1 in.
94.2 in.
Answer:
The correct option is C. 47.10 inches
Step-by-step explanation:
Diameter of the tire rim is given to be 15 inches
So, The radius of the tire rim will be 7.5 inches
Now, we need to find the circumference of the tire rim
And, The circumference of the tire rim is given by the formula :
Circumference = 2·π × radius
⇒ Circumference of the tire rim = 2 × 3.14 × 7.5
⇒ Circumference of the tire rim = 47.1 inches
Therefore, The correct option is C. 47.10 inches
