9(2+17)+13z=17
Answer:
9(19)+13z=17
171+13z=17
13z=171-17
Z=154/13 is the answer
Step-by-step explanation:
Pls mark me in brain list
Answer:
z = -154/13
Step-by-step explanation:
1.) Add the numbers
9(2+17)+13=17
9(19) = 13z = 17
2.) Multiply the numbers
9 x 19 + 13z = 17
171 + 13z = 17
3.) Rearrange terms
171 + 13z = 17
13z + 171 = 17
4.) Subtract 171 from both sides of the equation
13z + 171 = 17
13z + 171 - 171 = 17 - 171
5.) Simplify
Subtract the numbersSubtract the numbers13z = -154
Solution
z = -154/13

101+ 6x-5=180
6x=84
x=14
hope this helps!
Answer:
x = 14
Step-by-step explanation:
Since m || n, the two adjacent angles (101° and (6x-5)) must add up to 180°.
180° - 101° = 79°. Therefore, 6x - 5 = 79.
Add 5 to both sides, and the equation is 6x = 84.
Then divide both sides by 6 to get x = 14.

If 24 is increased to 60. Find the percent increase.
after completing the square what are the solutions to the quadratic equation below
x²-5x-6=3
Answer:
x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 5 x - 6 = 3
Hint: | Solve the quadratic equation by completing the square.
Add 6 to both sides:
x^2 - 5 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 25/4 to both sides:
x^2 - 5 x + 25/4 = 61/4
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 5/2)^2 = 61/4
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 5/2 = sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the first equation: Solve for x.
Add 5/2 to both sides:
x = 5/2 + sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the second equation: Solve for x.
Add 5/2 to both sides:
Answer: x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2
the house on one side of Elm Street follows a pattern the first five houses are numbers 41, 47 53, 59 and 65 if the pattern continues which of the following could be a house number on Elm Street. A- 75, B- 77, C- 81, D- 87
Step-by-step explanation:
Notice that:
47 - 41 = 6,53 - 47 = 6,59 - 53 = 6, 65 - 59 = 6.Every house number on the side of Elm Street is 6 more than the previous one.
If we continue this pattern, we will see the following house numbers:
65 + 6 = 71,71 + 6 = 77,77 + 6 = 83,83 + 86 = 89.Out of the options given, the only one whose number is on the side of Elm Street is 77. (B)

Shring's dining room table is round and has a radius of 4.5 feet. What is the tabletop's are ?
Answer:
Step-by-step explanation:
Radius 4.5 feet what’s is the tabletop area
The area of the table top is 63.62 square feet.
What is area in geometry?
'In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object.'
According to the given problem,
Radius of the table = 4.5 feet
Since, the table is round,
Area of a circle = [tex]\pi r^{2}[/tex]
= π × 4.5 × 4.5
= 63.617
Hence, we can conclude, the area of the table-top is 63.62 square feet.

Answer:
A
Step-by-step explanation:
First you do 5/2 to solve the ratio! That equals 2.5 btw. Then you have to selected the answer choice that is equivalent to that. So I just divided all them until I got a radio equal to 2.5! 45/18 equals 2.5 also! Therefore A (45 teachers to 18 students) was the correct choice!

Answer: a) one central angle is QPR
b) arc QTS is a semicircle
c) arc QR is a major arc
d) arc QTR = 235
e) arc QR = 125
Step-by-step explanation:
A central angle is an angle with its vertex as the midpoint of the circle.
A semicircle is half of a circle. Segment QS goes through the midpoint P splitting the circle in half : arc QTS and arc QRS are both semicircles.
The degree of a central angle is equal to the arc it encompasses. Central angle QPR is equal to 125, therefore arc QR is equal to 125 as well.
Given this information we can now find the remaining arc QTR. A circle is equal to 360 degrees. We know part of the circle is 125 degrees which means the remaking portion must be 235 degrees.
360 - 125 = 235
The value of a collectible toy is increasing exponentially. The two points on the graph
show the toy's initial value and its value 3 weeks afterward.
The question is incomplete. Here is the complete question.
Part A
The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.
Express the toy's value t, in dollars, as a function of time w in weeks after purchase.
Part B
Write an expression to represent the toy's value 10 days after purchase
Answer and Step-by-step explanation: An exponential function is of the form: [tex]y=ab^{x}[/tex]
Part A
Translating to the question, the toy's value as a function of time is
[tex]t=ab^{w}[/tex]
To determine constants a and b, we use points given by graph.
First, (0,5) to find a:
[tex]5=a.b^{0}[/tex]
a = 5
Now, (3,10) to determine b:
[tex]10=5b^{3}[/tex]
[tex]b=\sqrt[3]{2}[/tex]
b = 1.26
The toy's value as a function of time in weeks is [tex]t=5.(1.26)^{w}[/tex]
Part B
Since, the function is in weeks:
1 week = 7 days
w weeks = 10 days
[tex]w = \frac{10}{7}[/tex]
Replacing w:
[tex]t=5.(1.26)^{w}[/tex]
[tex]t=5.(1.26)^{10/7}[/tex]
Expression that represents toy's value after 10 days is [tex]t=5.(1.26)^{10/7}[/tex].
