Answer:
m= -12
Step-by-step explanation:
-15m-30=-12m+6
-3m=36
m=-12
Answer:
m = -12
Step-by-step explanation:
Simplify the Left Hand Side:
[tex]-5\left(3m+6\right) = -5\cdot \:3m+\left(-5\right)\cdot \:6[/tex]
[tex]=-15m-30[/tex]
Simplify the Right Hand Side:
[tex]-3\left(4m-2\right)=-3\cdot \:4m-\left(-3\right)\cdot \:2[/tex]
[tex]=-3\cdot \:4m+3\cdot \:2[/tex]
[tex]= -12m+6[/tex]
All together we have:
[tex]-15m-30=-12m+6[/tex]
Add 30 to both sides and simplify:
[tex]-15m-30+30=-12m+6+30[/tex]
[tex]-15m=-12m+36[/tex]
Add 12m to both sides and simplify:
[tex]-15m+12m=-12m+36+12m[/tex]
[tex]-3m=36[/tex]
Finally, we divide both sides by -3:
[tex]\frac{-3m}{-3}=\frac{36}{-3}[/tex]
And we get the answer
m = -12

An architect plans to build an extension for a rectangular bedroom. The bedroom is 5 meters wide, and the original length of the bedroom is 8 meters. The length of the bedroom's extension, in meters, is represented by x. The expression 5(x + 8) represents the area, in square meters, of the bedroom
(Answer the two questions below)
Part A: Create an equivalent expression without parantheses.
Part B: What does each term of your expression represent?
Answers
Part A. The equivalent expression for the area of the rectangle without parenthesis is 5x + 40 sq meters and
Part B. The term represents that the area has been increased by 5 times the amount of the extension.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know the area of a rectangle is (length×width).
So, The area of the rectangle before the length extension is,
= (5×8) sq meters.
= 40 sq meters.
Now, The length is extended by 'x' meters.
Therefore, The area of the rectangle after an extension in length is,
= 5(x + 8) sq meters.
= 5x + 40 sq meters.
The expression's phrase indicates that the area has grown by five times as much as the extension.

In the World Cup Downhill held at Panorama Mountain Village in British Columbia, the skiers raced 3514 m down the mountain. If the vertical height of the course was 984 m, determine the average angle of the ski course with the ground.
Answers
Answer:
16.3°
Step-by-step explanation:
This question above is a Trigonometry question that is solved using the formula of Sine
sin θ = Opposite/Hypotenuse
Opposite = The vertical height of the course = 984 m
Hypotenuse = The distance the skiers raced down the mountain = 3514 m
θ = The average angle of the ski course with the ground = ?
sin θ = 984 m/3514 m
sin θ = 0.2800227661
θ = arc sin (0.2800227661)
= 16.261563463°
≈ 16.3°
Therefore, the average angle of the ski course with the ground is 16.3°

4. Is the relation represented by the graph a function? Why or why not?
Answers
Answer:
The relation represented by the graph is not a function
Step-by-step explanation:
A function by definition is "a relation from a set of inputs to a set of outputs". For this graph there's no constant rate of change, you can't form a line with the points, and you can't write an equation or inequality from the points. There's no sort of relationship between the number of days and the number of students who are absent, so it's not a function.
Answer:
1. 1,7 2,10 3,5 4,7 5,9
2. 5
3. 2 10 Students were absent on day 2.
4.The graph is a function because each x-value is paired with a single y-value.

Answers
The answer i got is -1.55, im not sure though
The value of the given algebric expression is x - y when x=−5 1/4 and y=−6.8 will be 2.05.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
As per the given expression, x - y
x = - 5 1/4 = (-5 x 4 + 1)/4 = -19/4 = -4.75
y = -6.8
Substitute x and y into the above expression,
-4.75 - (-6.8) = 2.05
Hence "The value of the given algebric expression is x - y when x=−5 1/4 and y=−6.8 will be 2.05".

In a state with a population of 2,000,000 the average citizen
spends $6,000 on housing each year. What is the total spent on
housing for the state? Express answer in scientific notation.
Answers
Answer:
1.2×10¹⁰
Step-by-step explanation:
Given that,
The population of the state = 2,000,000
Average Citizen spends on housing = 6000
We need to find the total spent on housing for the state.
Total spent on housing for state = Population of State × Average Citizen
Total spent = 2,000,000 × 6,000
= 1.2×10¹⁰
Hence, the total spent on housing for the state is 1.2×10¹⁰.

The missing value is 6!
Step-by-Step Explanation:
First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)
Now, we can write this as a function, where we can represent the missing value as 'x'.
[tex]4+5+13+x=28[/tex]
In order to get the missing value, we must solve the equation.
Step 1: Simplify.
[tex]4+5+13+x=28\\22+x=28[/tex]
Step 2: Subtract 22 from both sides.
[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]
x is equal to 6, which means the missing volume of gas is 6!
