The property of equality applied to solve the equation is division property of Equality.
What is the property of equality?Property of equality says that by performing any mathematical operation, of both sides of an expression does not change the original value of the equation.
The equation given in the problem is,
[tex]0.36 x = -1. 8[/tex]
This equation is solved further by dividing both side of the expression with decimal number 0.36 as,
[tex]\dfrac{0.36}{0.36}x = -\dfrac{1. 8}{0.36}\\x=-5[/tex]
Here, the division operation is performed both sides of the equation to solve the equation. This does not change the original value of the equation and gives the value of unknown number.
Thus, the property of equality applied to solve the equation is division property of Equality.

Question 1 (5 points)
Dilate the rectangle below by a scale factor of 2. If the current side lengths are 15
and 8, what are the side lengths on the new dilated rectangle?
In your answer, give the new side lengths for the dilated image and explain how you
calculated them.
Answer:
AB and CD would be 30
AC and BD would be 16
Step-by-step explanation:
The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.

Answer:
6.4 = b and 7.8 = a
Step-by-step explanation:
Using the formula:
a^2 + b^2 = c^2
we can find the length of b
for the first triangle
now we just plug in the lengths.
5^2 + 4^2 = b^2
simplify into :
25 + 16 = b^2
add
41 = b^2
now in order to get rid of the ^2, we just find the square root of 41.
√41 ≈ 6.4
6.4 = b
Now we just need to solve for A
since we know
a^2 + b^2 = c^2 that must mean
c^2 - b^2 = a^2
so this is the formula we will be using.
now we just plug in the lengths of the second triangle into this equation.
10.5^2 - 7^2 = a^2
simplifies into
110.25 - 49 = a^2
subtract
61.25 = a^2
now we just find the square root of 61.25.
√61.25 = 7.8
7.8 = a
you can check this by putting it back in the formula
a^2 + b^2 = c^2
I will do this quickly (only for the second triangle)
we know
a = 7.8
b = 7
c = 10.5
7.8^2 + 7^2 = 10.5^2
simplifys into
60.84 + 49 = 110.25
60.84 + 49 ≈ 110
110.25 ≈ 110
110 = 110
which proves that this is correct.
Find x to the nearest tenth.
8
6
X
Answer:
x ≈ 5.3
Step-by-step explanation:
a²+b²=c²
c is always the hypotenuse in a right angle triangle.
6² + x² = 8²
36 + x² = 64
64 - 36 = 28
x² = 28
x = √28
Use calculator from here.
√28 = 5.29150262213
5.29150262213 ≈ 5.3
Because the number after 2, which is 9, is greater than 5, the nearest tenth is 5.3, not 5.2.
A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs.
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A.
Part C: If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values.
Will mark Brainlist!!!
Answer: PART A.
y= remaining height of candle
x= rate the candle burns down in inches per hour
8= original height of candle
the function would be y=8- 0.5x because the candle starts at a height of 8 feet and loses half an inch per hour.
You can use this function to create ordered pairs by putting in number at x which indicates the time:
x=1
y=8- (.5×1)= 7.5
(1, 7.5)
you can then do this for other numbers and get:
(2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)
PART B.
This equation is a function because all of the x-values had different y-values as seen in the coordinates (1, 7.5) (2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)
PART C.
If the rate was 0.4 inches an hour, it would still be a function because the rate is the only thing that changed making the new function y= 8- 0.4x.This equation would make coordinates of (0,8) (1, 7.6) (2, 7.2) (3, 6.8) and so on with each x value creating a different y value.
Step-by-step explanation: hope this helps

Select all the stories that can be represented by the diagram.
Diego spends $1 on 7 Stickers and 3 marbles

Noah shares 7 grapes with 3 friends. He eats 1 and gives each friend the same number of grapes.
Andre studies 7 hours this week for end-of-year exams. He spends 1 hour on English and an equal number of hours each on math, science, and history.
Lin spends $3 on 7 markers and a $1 pen
Answer: Choice C and Choice D
========================================================
Explanation:
Choice A doesn't work because it the $1 should be $7 instead.Choice B doesn't work because it should be Elena spending $7 total on 3 notebooks and a $1 pen. The x is the amount per notebook.Choice C does work. If x is the number of grapes Noah gives each friend, then 3x is the total amount Noah gives over. Then 3x+1 is the number of grapes total. That +1 at the end is the grape Noah eats. We end up with 3x+1 = 7 because Noah starts off with 7 grapes.Choice D works also. The x is the number of hours for math, science and history each. So 3x is the combined time of those three classes. Add on 1 to get 3x+1 to represent all 7 hours, ie 3x+1 = 7.Choice E does not work. If it was her spending $7 on 3 markers and a $1 pen, then it would work.Answer:
[] Noah shares 7 grapes with 3 friends. He eats 1 and gives each friend the same number of grapes.
[] Andre studies 7 hours this week for end-of-year exams. He spends 1 hour on English and an equal number of hours each on math, science, and history.
Reasoning:
[✗] The first story, with Diego, does not work because the whole is $1 in the problem and $7 in the diagram.
[✗] The second story, with Elena, does not work because the 7 is ignored entirely and the x becomes a known value, 57.
[✓] The third story, with Noah, does work because he splits seven grapes equally among three friends (the x's) and eats one.
[✓] The fourth story, with Andre, does work because 7 hours were spent studying. One on English and the rest (three subjects) split evenly (x).
[✗] The fifth story, with Lin, does not work because the total is $3 when it should be 7.

In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If 3/4 of the drink is apple juice and 1/10 is orange juice then write the ratio of cranberry juice to apple juice to orange juice in its simplest form.
Answer:
15/20 : 2/20 : 3/20 or you could put 3/4 : 1/10 : 3/20 but that's up to your teacher
Step-by-step explanation:
We know that there are 3 ingredients.
3/4 apple juice
1/10 orange juice
We want to know how much cranberry juice to apple juice to orange juice.
First, let's start with getting common denominators.
The LCD (least common denominator) between these two fractions is 40. (4 * 10)
So:
3/4 * 10/10 = 30/40
1/10 * 4/4 = 4/40
Now we know them with equal denominators. Now let's subtract them from the whole (40/40) to find out how much cranberry juice.
40/40 - 30/40 - 4/40 = 6/40
Cranberry juice = 6/40 of the whole.
Now we can find the ratio in its simplest form.
30/40 : 4/40 : 6/40
Can we simplify these fractions? yes.
The can all be simplified by 2
15/20 : 2/20 : 3/20
Since 2 can't be simplified by anything but 2 or 1, and 15 and 3 cannot be simplified by 2, this is your answer.
or you could put 3/4 : 1/10 : 3/20 but that's up to your teacher.
