Answer:
Step-by-step explanation:
Every 1 hour, 7 screams are caused
the first part is 6 hours, so that means we multiply 6 x 7, which is 42
The second one has 56 screams, so this means we divide 56 and 7 to get 8
The last one is the same as the first one, we multiply 7 and 12 to get 84
Hope this helps : ]
For 6 hours, there are 42 screams, for 8 hours, there are 56 screams and for 12 hours, there are 84 screams.
What are Proportions?A proportion is an equation in which two ratios are set equal to each other.
Given that two number lines, one is moving like, 0,1,2,...
And second one is moving like 0,7,14....
Therefore, studying the number lines, we get,
6 hours = 7*6 = 42 screams
8 hours = 7*8 = 56 screams
12 hours = 7*12 = 84 screams
Hence, For 6 hours, there are 42 screams, for 8 hours, there are 56 screams and for 12 hours, there are 84 screams.

Answer:
x= 72.72 (with a line over it)
Step-by-step explanation:
(x - 5) + (1.4x) + (x) + (x + 35) = 360
Step 1. Simplify both sides of the equation.
x + 5 + 1.4x + x + x + 36 = 360
(x + 1.4x + x + x) + (5 + 35) = 360 (combine like terms)
4.4x + 40 = 360
Step 2. Subtract 40 from both sides.
(4.4x + 40) - 40 = (360) - 40
4.4x = 320
Step 3. Divide both sides by 4.4
4.4x/4.4 = 320/4.4
x = 72.72 (72 repeats, so 72 with a line over it)

What is the slope of this line? Enter your answer as a fraction in the simplest term in the box.
Answers
Answer:
-1/1
Step-by-step explanation:
The slope of a line is always the rise over run where rise is up or down(y axis) and the run is side to side(x-axis). Then, if the line is going up, your answer will be negative. So, using the points given, you can tell that the line is moving 2 units down while also moving 2 units to the left. Another way to calculate this is y2-y1 over(/) x2-x1, the y equals your y coordinates, x equals your x coordinants,d the 1 and 2 represent which points. Whichever point you use, you have to use the same coordinants fr the same value. For example, if you took the points (-2,0) and (0,-2) and you used (0,-2) as your second value, you can enter those into the formula.
(-2)-(0) / (0)-(-2) = -2 / 2

3x+8(2x - 6) = 2 + 14x
Answers
Answer:
x=10
Step-by-step explanation:
Simplifying 3x + 8(2x + -6) = 2 + 14x
Reorder the terms: 3x + 8(-6 + 2x) = 2 + 14x 3x + (-6 * 8 + 2x * 8) = 2 + 14x 3x + (-48 + 16x) = 2 + 14x
Reorder the terms: -48 + 3x + 16x = 2 + 14x
Combine like terms: 3x + 16x = 19x -48 + 19x = 2 + 14x
Solving -48 + 19x = 2 + 14x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14x' to each side of the equation. -48 + 19x + -14x = 2 + 14x + -14x Combine like terms: 19x + -14x = 5x -48 + 5x = 2 + 14x + -14x
Combine like terms: 14x + -14x = 0 -48 + 5x = 2 + 0 -48 + 5x = 2
Add '48' to each side of the equation. -48 + 48 + 5x = 2 + 48
Combine like terms: -48 + 48 = 0 0 + 5x = 2 + 48 5x = 2 + 48
Combine like terms: 2 + 48 = 50 5x = 50
Divide each side by '5'. x = 10
Simplifying x = 10

Step-by-step explanation:
The value of a= 17.5, b=-14 and c=-28.
What is function?A function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.
Given function:
f (x) = 3x – 1.
Also,
x f(x)
-5 a
-2 7
4 b
8 c
Now, using the proportionality
k = y/x
k = 7 / (-2)
k = -3.5
So, -3.5 = a/ (-5)
-3.5 x (-5) = a
a= 17.5
again, -3.5 = b/4
b= -14
Lastly, -3.5 = c/8
c= -28.
Hence, the value of a= 17.5, b=-14 and c=-28.

From the information given, we can make this equation:
[tex]\frac{0.15}{60.00} =\frac{x}{250,000}[/tex]
Now all we need to do to find the answer is to solve for x.
