What is x? Please help quickly!
Answer:
27 1/3
Step-by-step explanation:
Since both angles form a straight line of 180, you can set your formula up as
180=4x+2x+16
180-16=6x
164=6x
164/6=x

Answer:
The inverse is 5/(2-x)
Step-by-step explanation:
Firstly, let us represent the inverse as y
thus;
y = (2x+ 1)/x-4
y(x-4) = 2x + 1
xy - 4 = 2x + 1
2x - xy = -4-1
2x-xy = -5
x(2-y) = 5
x = 5/2-y
Now, switch the alphabets again
y = 5/(2-x)

if I divide the units of the scaled rectangle by the original you will get
[tex]18 \div 9 = 2 \\ 6 \div 3 = 2[/tex]
Answer:
C
Step-by-step explanation:
Area of the original one = 9 * 3 = 27 cm^2
Area of the scaled one = 18 * 6 = 108 cm^2
108 / 27 = 4
*please help and explain how you got the answer!*
Answer:
0
Step-by-step explanation:
A= (4-1)^3
simplify A to be 3^3
Which gives us 27
B=(2*3)^2-9
simplify B
first multiply the 2 numbers in paranthesis which gives us 6. raise it to the power of 2 which is 39 and then subtract 9. Gives us 27.
C=15^3*4-12
Simplify the exponent first. 3*4 gives us 12 and 12-12 equals 0. Anything raised to the power of 0=1
If A-B^C is the equation we can write 27-27 raised to the power of 1 which is 0
How would you graph the solution set of x/6 ≤ -18
Multiply both sides by 6 and you'll end up with x ≤ -108
The graph will involve a closed circle at -108 and shading to the left
See below.
We use a closed circle to include the endpoint -108 itself. If we didn't have the "or equal to" part, then we'd be using an open hole at the endpoint instead.
The shading to the left is to describe values smaller than -108. Overall, the entire thing consists of stuff smaller than -108 or -108 itself.

Answer:
[tex]\frac{1}{3(x-2)}[/tex]
Step-by-step explanation:
Hi there!
We need to multiply the fractions:
[tex]\frac{x+3}{12x}[/tex]×[tex]\frac{4x}{x^{2}+x-6}[/tex]
Before we multiply, we can cancel out and factor the polynomials to make multiplying easier
First, we can factor x²+x-6
1 (in front of +x) is the sum of two numbers and -6 is the product of those numbers
Those numbers are -2 and 3
so when we factor, we get:
(x-2)(x+3)
here are the fractions so far:
[tex]\frac{x+3}{12x}[/tex]×[tex]\frac{4x}{(x+3)(x-2)}[/tex]
we can cancel out x+3 on both fractions
[tex]\frac{1}{12x}[/tex]×[tex]\frac{4x}{x-2}[/tex]
we can also cancel out 4x from both fractions
[tex]\frac{1}{3}[/tex]×[tex]\frac{1}{x-2}[/tex]
now multiply the fractions together
[tex]\frac{1}{3(x-2)}[/tex]
So the first option is your answer
Hope this helps! :)

If y − 3 = 3x, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
(Thanks in advance)
Answer:
The first chocie (0,3), (1,6), (2,9)
Step-by-step explanation:
Just plug each point into the equation and see if it is correct.
y-3 = 3x
for (0,3) --> 3-3=3(0) -->0 = 0 true
for (1,6) --> 6-3 = 3(1) --> 3=3 true
fpr (2,9) -->9-3 = 3(2) --> 6=6 true
6x - 2y = -22
х+4y = -8
Answer:
x = -4 y = -1
Step-by-step explanation:
x + 4y = -8
4y = -x - 8
y = -1/4x - 2
6x - 2(-1/4x - 2) = -22
6x + 1/2x + 4 = -22
13/2x + 4 = -22
13/2x = -26
x = -4
(-4) + 4y = -8
-4 + 4y = -8
4y = -4
y = -1
Answer:
x = -4 y = -1
Step-by-step explanation:
Solve for each variable by creating an equation and plugging it in to the other given equation.
- Equation to solve for x: x = -4y - 8
- Plug this equation into the other, solving for y so you have:
6(-4y-8)- 2y = -22 => -24y - 48 - 2y = -22 => -26y = 26 => y = -1
- Take this value and plug into the equation we created for x:
x = -4(-1) - 8 => x = 4 -8 => x = -4
- Check your work with given equation 6x -2y = 22:
6(-4) - 2(-1) = -22 => -24 +2 = -22 => -22 = -22

Answer:
No
Step-by-step explanation:
The ratios of triangle side lengths are ...
4 : 6 : 8 = 2 : 3 : 4
This is an arithmetic progression.
The only arithmetic progression of side lengths that makes a right triangle is ...
3 : 4 : 5
The triangle is not a right triangle, so AB is not a tangent.
Out of 200 students in a school, 30 have brown sandals. What is the probability that a student chosen at random would have brown sandals?
Answer:
There is a 15% chance a student chosen at random would have brown sandals.
Step-by-step explanation:
The required probability will be 0.15 that a student chosen at random would have brown sandals.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
the probability = number of favorable outcomes / total number of outcomes.
We have been given that out of 200 students in a school, 30 have brown sandals.
To determine the probability that a student chosen at random would have brown sandals.
The probability = number of favorable outcomes / total number of outcomes.
The probability = 30 / 200
The probability = 0.15
Thus, the required probability will be 0.15 that a student chosen at random would have brown sandals.

According to money exchange rate of Nepal Rastra Bank, the
purchase and selling rate of 1 U.S. dollar are NRs.103.72 and
NRs.104.32 respectively then,
i. How many American dollar can be exchanged withNRs.57, 376
Answer:
Purchase rate = 553.18 U.S dollar
Selling rate = 547.90 U.S dollars
Step-by-step explanation:
Purchase rate
1 U.S. dollar = NRs.103.72
Selling rate
1 U.S. dollar = NRs.104.32
How many American dollar can be exchanged withNRs.57, 376
Purchase rate
1 U.S. dollar = NRs.103.72
Amount of U.S. dollar = NRs.57, 376 / NRs.103.72
= 553.18164288468
Approximately
553.18 U.S dollar
Purchase rate = 553.18 U.S dollar
Selling rate
1 U.S. dollar = NRs.104.32
Amount of U.S. dollar = NRs.57, 376 / NRs. 104.32
= 547.89915966386
Approximately,
547.90 U.S dollars
Selling rate = 547.90 U.S dollars

Answer:
Radius
Step-by-step explanation:
Any segment with one endpoint at the center of the circle and the other endpoint on the circle is the radius. This information is very important, because when you want to find the area of a circle you multiply the radius by itself twice then multiply that by pi. The diameter (second option) is a segment where one endpoint is on the circle and the other endpoint is on the other side of the circle. The diameter is twice the radius. Good luck!

A side of the triangle below has been extended to form an exterior angle of 128°. Find the value of x.
the value of x.
Answer:
x = 104
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
24+x = 128
Subtract 24 from each side
24+x-24 =128 -24
x =104

A circle has a center (-5, -6) and the lowest point along the edge is (-5, -9) .
What is the equation of the circle in standard form?
(x+5)2+(y+6)2=9
(x+5)2+(y+6)2=36
(x+25)2+(y+36)2=36
(x+25)2+(y+36)2=9
Answer:
(x+5)² + (y+6)² = 9
Step-by-step explanation:
the equation of a circle is
(x-a)² + (y-b)² = r²
with (a,b) being the center coordinates and r being the radius (half the diameter).
so, in our case here a = -5, b = -6
and r is the distance from the center to any point of the circle. that includes the lowest point asking the edge.
the distance of (-5,-6) to (-5,-9) is 3, as both points have the same x-value, and the only difference is in the y-value.
as we are talking about a distance, negative values don't make sense. so, we need the absolute value of -9 - -6 or then of -3, and that is 3.
