Step 2:
- 5z - 12 = 18 Open Parenthises
Step 3:
- 5z = 30 Add 12 on both sides
Step 4:
z = 30 ÷ - 5 Divide
Answer:
z = - 6
Hope This Helps :)
Answer: z = -6
Step-by-step explanation:
Hi there! I will be showing you how to solve the given equation. If you have any questions feel free to comment it down below.
Step 1: Remove parentheses.
-5z - 12 = 18
Step 2: Add 12 to both sides.
-5z = 18 + 12
Step 3: Simplify 18 + 12 to 30.
-5z = 30
Step 4: Divide both sides by -5.
z = [tex]-\frac{30}{5}[/tex]
Step 5: Simplify [tex]\frac{30}{5}[/tex] to 6.
z = -6
I hope I helped you :)

Find the value of X. Then find the measure of each labeled angle.
Answer:
x=118, top right angle is 118, bottom right is 62, bottom left is 90, and top left is 90
Step-by-step explanation:
1. since a quadrilateral's andles sum up to 360, these must sum up to 360
2. since the two sides (top and bottom) are parallel, the bottom left and top left angles add up to 180 (it's a conjecture)
3. this means that (x-56) + x+ 90 + (180-90)=360
4. simplify: 2x + 124 = 360
5. solve: x= 118
6. this means top right angle is 118, bottom right is 62, bottom left is 90, and top left is 180-90=90

Step-by-step explanation:
The temperature in Fairbanks, Alaska, changed from 0F at 6 pm to 4F at 11 pm . Between 11 pm and 5 am , the temperature dropped by 6 degrees . Which number line represents the temperature at 5 am
The number line extending towards -2 represents the correct number line.
What is number line?
A line on which numbers are marked at intervals, used to illustrate simple numerical operations.
Given is the temperature in Fairbanks, Alaska, changed from 0 F at 6 pm to 4 F at 11 pm . Between 11 pm and 5 am , the temperature dropped by 6 degrees.
Between 6 pm and 11 pm : 4 - 0 = 4 F
The temperature at 5 AM would be : 4 F - 6 F = - 2 F
Therefore, the number line extending towards -2 represents the correct number line.

Answer:
first I put -2.32 into a improper fraction and then I simplified to this - 2 8/25
We need to find the given numbers mixed fraction representation.
The given numbers mixed fraction form is [tex]-2\dfrac{8}{25}[/tex].
The given number is [tex]-2.32[/tex].
Let us remove the negative sign for solving the question.
The negative sign can be added at the end.
[tex]2.32=2+0.32[/tex]
[tex]=2+\dfrac{32}{100}[/tex]
Dividing the fraction by common factors we get
[tex]2+\dfrac{8}{25}=2\dfrac{8}{25}[/tex]

Solve x^2 - 16x = -12 by completing the steps.
First, subtract ____ from each side of the equation.
Answer:
You would subtract -12 from both sides!
Explanation:
The eqaution will become like this:
[tex]x^{2}[/tex] - 16x + 12 = 0
Then you would solve it with the Quadratic Equation formula.
Answer:
First, subtract 60 from each side of the equation.
Next, add 64 to each side of the equation to complete the square.
Now, write x² - 16x + 64 = -8 as (x-8)^2=-8
Take the square root of both sides to get the solutions.

USING STRUCTURE An athletic facility is building an indoor track. The track is composed of a rectangle and two semicircles, as shown. A drawing shows an indoor track. It is shaped like a rectangle with a semi-circle on each of the shorter sides. The length of the rectangle is labeled x. The radius of each semi-circle is labeled r. A. Write a formula for the perimeter of the indoor track. $P=$ b. Solve the formula for $x$ . $x=$ Question 2 c. The perimeter of the track is 660 feet, and $r$ is 50 feet. Find $x$ . Round your answer to the nearest foot. $x=$ feet
Answer:
Step-by-step explanation:
Find the digram attached.
Perimeter of the track = perimeter of the rectangle + perimeter of the 2semicircles
Perimter of a rectangle = 2(x+r) where:
x is the length
2r is the width of the rectangle = diameter of the semicircle
Perimeter of semicircle = 2πr/2 = πr
Perimeter of 2semicirle = 2πr
Perimeter of the track = 2(x+2r) + 2πr
r is the radius if the semicircle
Expand
Perimeter of the track = 2x+4r + 2πr
Perimeter of the track = 2(x+2r+πr)
b) Given P = 2(x+2r+πr), we are to make x the subject of the formula.
P = 2x+4r+2πr
P-4r-2πr = 2x
Divide both sides by 2.
(P-4r-2πr)/2 = 2x
x = (P-4r-2πr)/2
c) Given
P = 600fr
r = 50ft
x = (600-4(50)-2π(50))/2
x = (600-200-100(3.14))/2
x = 400-314/2
x = 86/2
x = 43ft
Hence the value of x to nearest foot is 43ft
