Ruth decides to test the method of proportions and similar
triangles to find the height of a tree. She decides to again find the
height of a tree she had measured earlier in the day at 10 A.M. This
time, she decides to use this method at 5 P.M. in the evening. She
measures the length of the tree's shadow and finds it to be 48 feet
long this time. Then she holds a 12-inch ruler perpendicular to the
ground and finds that it casts a 24-inch shadow. How tall will she find
the tree?

Answers
Answer: 5x + 16
Step-by-step explanation: distribute, add the numbers, and combine like terms.
Answer:
x = -3.2
Step-by-step explanation:
First, solve parenthesis:
2(x+6)+3x+4= 0 (Given)
2x + 12 + 3x + 4 = 0 (distributive property of equality)
Then, you comibine like terms:
2x + 12 + 3x + 4 = 0
5x + 16 = 0 (Combining like terms)
And then, move the variables to the left and constants to the right:
5x + 16 = 0
5x = -16 (Subtraction property of equality) You subtract 16 from both side, since the variable is on the right already you leave it that way.
Finally, you divide both sides to get the answer ( solve for X):
5x = -16
x = -3.2 (division property of equality)
There is your answer!

Edward doesn't know how to do math. Can you help me help him lol
Answers
Answer: d = 147/4 or 36.75
Edward didn't isolate for 'd' by rearranging the terms.
(4/7)d = 21 (Multiply both sides by 7 to get rid of the 7 on the left side)
4d = 21 · 7
4d = 147 (Divide both sides by 4 to isolate for d)
d = 147/4 or 36.75
Factor out the coefficient of the variable term.
The expression 1.5y – 6 factored is
Answers
Answer:y=4
Step-by-step explanation: Simplifying
1.5y + -6 = 0
Reorder the terms:
-6 + 1.5y = 0
Solving
-6 + 1.5y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 1.5y = 0 + 6
Combine like terms: -6 + 6 = 0
0 + 1.5y = 0 + 6
1.5y = 0 + 6
Combine like terms: 0 + 6 = 6
1.5y = 6
Divide each side by '1.5'.
y = 4
Simplifying
y = 4
The equivalent equation, if 6 is factored out from the expression is 6(0.25y - 1)
Given a linear equation y = mx + b where b is the constant.
Given the linear equation f(y) = 1.5y - 6, we can see that 6 is the constant in the expression.
Factoring out 6 from the expression
[tex]f(y) = 1.5y-1.6\\f(y)=6(\frac{1.5y}{6}-\frac{6}{6} )\\f(y)=6(\frac{0.25y}{1} -1)\\f(y) = 6(0.25y-1)[/tex]
Hence the equivalent equation, if 6 is factored out from the expression is 6(0.25y - 1)

Explain why we need to have a common denominator in order to add or subtract fractions.
Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate.
Answers
Answer: The denominator of a fraction tells you the relative size of the pieces. Therefore, the reason fractions need a common denominator before adding or subtracting is so that the numbers of pieces you are adding/subtracting are all the same size.
Answer:
We need to have a common denominator in order to subtract different fractions because if we have an example like.
5/2 - 6/8 we cannot do that because the denominator is not alike.
We have to use multiplication to help us here.
2 x 8 = 16 !
So. no we have 5/16
so now we do 5 x 8 = 40
So now my new fraction is - 40/16 BUTTTT 40/16 is an improper fraction. so 40/16 = 5/2
Now we are back at the square 1 so now we have to fix 6/8.
8 x 6 = 48
6 x 6 = 36.
--
2 x 24 = 48.
5 x 24 = 120 or 12
now we have 12/48 and 36/48.
We can subtract now!

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes. If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.
A. Yes; Machine A and Machine B make 77.5 ounces in 10 minutes. 77.5 > 72, so there will be enough popcorn.
B. Yes; Machine A and Machine B make 87.5 ounces in 10 minutes. 87.5 > 72, so there will be enough popcorn.
C. No; Machine A and Machine B make 67.5 ounces in 10 minutes. 67.5 < 72, so there will not be enough popcorn.
D. No; Machine A and Machine B make 30.75 ounces in 10 minutes. 30.75 < 72, so there will not be enough popcorn.
Answers
Answer: Machine A makes popcorn at a rate of 4.25 ozs per minute (12.75oz/3min).
Machine B makes popcorn at a rate of 4.5 ozs per minute (18oz/4min).
Machine A will make 4.25oz/min * 10minutes = 42.5oz of popcorn after 10 minutes
Machine B will make 4.5oz/min * 10 minutes = 45oz of popcorn after 10 minutes
After 10 minutes there will be a total of 42.5oz (Machine A) +45oz (Machine B) = 87.5oz.
So the answer is: Yes there will be (more than) enough popcorn if both machines make popcorn for 10 minutes.
If the question is wondering how many 9oz bags they can fill: 87.5oz/9oz per bag = 9.7222 bags. The machines can fill 9, 9oz, bags with some popcorn leftover.

Answers
Answer:
The unit rate of y per x is 9
Step-by-step explanation:
In this question, we are asked to give the unit rate of x.
To do this, we will critically look to establish the relationship between both set of values.
Looking at the values critically, we can see that the values in the first brackets, when multiplied by 4 will give the values in the second bracket. Hence we can say that the values in the second bracket are multiples of the first by 9.
