Answer:
x= 8.5, 2x=17, (9x+5)=81.5
Step-by-step explanation:
since the sum of the interior angles of a triangle is 180 degrees, you must add all of the angles and set them equal 180:
[tex]2x + 2(9x+5) = 180[/tex]
next distribute the 2 to 9x + 5.
[tex]2x + 18x + 10 = 180[/tex]
next combine like terms (2x and 18x) and subtract 10 from 180.
[tex]20x = 170[/tex]
finally, divide 170 by twenty.
[tex]\frac{20x = 170}{20}\\,x=8.5[/tex]
the final answer is x=8.5
once x is determined, you can solve 2x and 9x+5.
[tex]2(8.5)=17\\\\9(8.5) +5 =81.5[/tex]
Pls help I hate math
A water container in the shape of a rectangular prism has a length of 2 meters, a width of 3/4 meter, and a height of 1/2 meter. If a cubic meter of water costs $1.20, what is the cost to fill the container?
Answer:
look below!
Step-by-step explanation:
For the length I think you meant 32, and if you did it is $14.40
If not and you meant length of 2 it is $0.90
Answer:
lxwxh for volume.
2x.75x.5 = .75 cubic meters.
.75 percent of 1.20 = .90.
90 cents is the answer.

Answer:
A=18 because 6+18 (was 6+a) is 24 - 11 = 13
Step-by-step explanation:
A=18
Answer:
a = 4
Step-by-step explanation:
add 11 on the = side 11+13 = 24
now you're left with: 6a=24
divide 6÷24
a= 4

Solve the following rational equation plz help!!
Answer:
x = [tex]\frac{9}{4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x^2+x}[/tex] ← factor denominator
[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x(x+1)}[/tex]
[ x ≠ 0, x ≠ - 1 as these would make the terms undefined ]
Multiply through by x(x + 1)
4x² - 5(x + 1) = 4
4x² - 5x - 4 = 4 ( subtract 4 from both sides )
4x² - 5x - 9 = 0 ← in standard form
(x + 1)(4x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
4x - 9 = 0 ⇒ 4x = 9 ⇒ x = [tex]\frac{9}{4}[/tex]
However, x ≠ - 1 for reason given above, then
solution is x = [tex]\frac{9}{4}[/tex]
if ABCD is a parallelogram then what is the measure of < A - <C
Answer:
The answer is 0.
Plea look at the photo of Parallelogram properties.
Question: Find the measurement indicated in each parallelogram.
Please explain it you can:)
Answer:
1. 45
2. 105
3. 95
4. 85
Step-by-step explanation:
For problems 1 and 4:
Consecutive angles are supplementary in a parallelogram, which means they equal 180.
180 - 135 = 45
180 - 95 = 85
For problems 2 and 3:
Opposite angles are congruent or equal each other in a parallelogram,
equivalent Find the number that makes the ratio equivalent to 1:7. 4:
Answer:
28
Step-by-step explanation:
Ratios are like fractions. Since you're finding an equivalent ratio, u can set them up like equivalent fractions and put an x where the missing number would go:
[tex]\frac{1}{7} = \frac{4}{x}[/tex]
You can either cross multiply and then solve for x, but it's easier to just think about it. The fractions are equivalent, right? So for them to be the same you'd have to do to the bottom what u do to the top.
To get from 1 to 4, you multiply by 4. By that logic, to get from 7 to x you'd have to multiply by 4 as well. Therefore x = 7x4, which is 28.
So x = 28

There’s no further instructions on this please help
Please help
Answer:
Assuming that the line is completely horizontal, that the 1 at the top is indicating the question number, and that the 3 is the only other piece of information given about the line, I think it's y = 3. I hope this is right, sorry because that's a terrible question. Good luck!

Find f^-1(x) where
f(x) = 3x+2/x
Given:
Consider the function is
[tex]f(x)=\dfrac{3x+2}{x}[/tex]
To find:
The inverse of the function, .i.e., [tex]f^{-1}(x)[/tex].
Solution:
We have,
[tex]f(x)=\dfrac{3x+2}{x}[/tex]
Putting f(x)=y, we get
[tex]x=\dfrac{3y+2}{y}[/tex]
Isolate the variable y.
[tex]xy=3y+2[/tex]
[tex]xy-3y=2[/tex]
[tex]y(x-3)=2[/tex]
[tex]y=\dfrac{2}{x-3}[/tex]
Putting [tex]y=f^{-1}(x)[/tex], we get
[tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex]
Therefore, the inverse function is [tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex].

This triangle has one side that lies on an extended line segment. Based on this triangle, what statement about x is true? A. x = 27 because 180−109−44=27 B. x = 65 because 109−44=65 and 44 + 65 = 109 C. x = 71 because 180−109=71 D. x = 153 because 109 + 44 = 153 and 153−44=109
MEASUREMENTS (down below)
A triangle with base on an extended line. Two angle measures are given. Top interior angle is forty-four degrees. Lower right exterior angle is one hundred nine degrees. Lower left interior angle is labeled x degrees.
Answer:
B. x = 65 because 109−44=65 and 44 + 65 = 109
Step-by-step explanation:
Given :
The triangle below :
Sum of interior angles of a triangle :
(44° + x + (180 - 109) = 180°
44° + x + 71° = 180
115° + x = 180°
x = 180° - 115°
x = 65°

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 3)(0,3) and (4, 7203)(4,7203).
Answer:
[tex]y = 3(7)^x[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,3)[/tex]
[tex](x_2,y_2) = (4,7203)[/tex]
Required
Determine an exponential function
Substitute 0 for x and 3 for y in [tex]y=ab^x[/tex]
[tex]3 = ab^0[/tex]
[tex]3 = a*1[/tex]
[tex]3 = a[/tex]
[tex]a = 3[/tex]
Substitute 4 for x and 7203 for y in [tex]y=ab^x[/tex]
[tex]7203= ab^4[/tex]
Substitute 3 for a
[tex]7203= 3*b^4[/tex]
Divide both sides by 3
[tex]2401= b^4[/tex]
Take 4th root of both sides
[tex]\sqrt[4]{2401} = b[/tex]
[tex]7 = b[/tex]
[tex]b = 7[/tex]
Substitute 3 for a and 7 for b in [tex]y=ab^x[/tex]
[tex]y = 3(7)^x[/tex]
