The addition property of equality was used to solve this equation. option A is correct.
A solution is given we have to determine the solution contains which property of equality.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
x − 5 = -14
x − 5 + 5 = -14 + 5
x = -9
We can see, in step 2 5 is added to both sides of an equality, which implies the property of additions.
Thus, the addition property of equality was used to solve this equation. option A is correct.

Which of the following is a solution of the equation -5x + 2 = -13: answers: x=-9, x=75 x=3 x=-3
Answer:
x= 3
Step-by-step explanation:
1. -5(3) + 2 = -13
2. -15 + 2 = -13 A positive times a negative will always equal a negative
3. -13 = -13 Whenever you add anything to a negative number, the
number becomes smaller
Ex: -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, ...........
Although the number itself becomes smaller, its value
becomes bigger
Hope this helps.

When a 49 pound weight is attached to a spring, the spring
stretches 7 inches. Assume that the length of the spring y varies directly
with the weight attached x. Write and solve a direct variation equation to
find the length of the spring when a 63 pound weight is attached.
im not for sure but I think the answer is 9! my reasoning is below,,
Step-by-step explanation:
[tex] \frac{49}{7} = \frac{63}{x} [/tex]
do the crossing method and it would result in this
(49×x) = (63×7)
after simplifying both sides
49x = 441
divide both sides by 49 and the result will be
x = 9 !!

Answer:
[tex]x=43\\[/tex]°
Step-by-step explanation:
considering m║n, the two labeled angles are alternate exterior angles. alternate exterior angles are equivalent. So you will have an equation of:
[tex]4x-27=3x+16[/tex]. Add 27 on both sides and get: [tex]4x=3x+43[/tex]. subtract [tex]3x[/tex] from both sides to get: [tex]x=43[/tex]°.
Using the diagram below, what is the horizontal distance between the control tower and the plane?
Answer:
x = 664.093 m
Step-by-step explanation:
tan∅ = opposite over adjacent
Since we are trying to find the horizontal distance, that means we are dealing with the bottom length and not the hypotenuse (the diagonal length):
Our theta (∅) = 52°
Our opposite = 850 m
Our adjacent = x m
tan52° = 850/x
xtan52° = 850
x = 850/tan52°
x = 664.093 m

What is the solution for the equation 6x - 8 = 4x? x =
Answer:
x = 4
Step-by-step explanation:
6x - 8 = 4x
subtract 4x from both sides of the equation
6x - 4x -8 = 4x - 4x
2x - 8 = 0
add 8 to both sides of the equation
2x - 8 + 8 = 0 + 8
2x = 8
divide both sides of the equation by 2
2x/2 = 8/2
x = 4
Answer:
x = 4.
Step-by-step explanation:
6x - 8 = 4x
6x - 4x - 8 = 0
6x - 4x = 8
2x = 8
x = 4.
the prices of stock A at 9am was $12.18 since then the price has been increasing at the rate of $0.06 each hour. At noon the price of stock B was $12.68. It begins to descrease at the rate of $0.09 per hour. If the 2 rates continue in how many hours will the prices of the two stocks be the same?
Answer:
3.33hours
Step-by-step explanation:
Where the number of hours = h
the prices of stock A at 9am was $12.18 since then the price has been increasing at the rate of $0.06 each hour.
The Algebraic expression =
$12.18 + $0.06 × h
12.18 + 0.06h
At noon the price of stock B was $12.68. It begins to descrease at the rate of $0.09 per hour.
$12.68 - $0.09×h
12.68 - 0.09h
If the 2 rates continue in how many hours will the prices of the two stocks be the same?
Stock A = Stock B
12.18 + 0.06h = 12.68 - 0.09h
Collect like terms
0.06h + 0.09h = 12.68 - 12.18
0.15h = 0.5
h = 0.5/0.15
h = 3.3333333333 hours
h = 3.33hours

Answer: 2x-9y=1
Step-by-step explanation:
(this is how i found it don't know if this is how you learned it though)
Subtract 20 from both sides of -3x-8y=20, so that it becomes -3x-8y-20
Subtract 19 from both sides of -5x+y=19, so you get -5x+y-19
Subtract like terms from both equations (-3x-8y-20)-(-5x+y-19), which gives you 2x-9y-1
-3--5=2, -8-1=-9, -20--19=-1
Add 1 to both sides and you get 2x-9y=1
Max is a real estate agent and receives 2% commission on the first $400 000 and 1.5% on the value thereafter.
Find his commission for selling a property worth $920000. Please help me.
Answer:
commission = 15800
Step-by-step explanation:
920000 - 400000 = 520000
400000 x .02 = 8000
520000 x .015 = 7800
8000 + 7800 = 15800
4. Which of the following could be the areas of the three squares shown?
Answer:
Option (A)
Step-by-step explanation:
Three squares shown in the figure are formed on the sides of the given right triangle.
By Pythagoras theorem,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
Area of the square on the hypotenuse = Area of the square on the leg 1 + Area of the square on leg 2
Option (A).
95 = 40 + 55
True.
Option (B).
45 ≠ 35 + 25
False.
Option (C).
100 ≠ 10 + 10
False.
Option (D).
1200 ≠ 40 + 30
False
Therefore, Option (A) shows the areas of three squares.
