[tex] \boxed{ \bold{ \huge{\boxed{ \sf{x = - 11}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{5x + 23 = 2(x - 5)}[/tex]
Distribute 2 through the parentheses
⇒[tex] \sf{5x + 23 = 2x - 10}[/tex]
Move 2x to left hand side and change it's sign
⇒[tex] \sf{5x - 2x + 23 = - 10}[/tex]
Move 23 to right hand side and change it's sign
⇒[tex] \sf{5x - 2x = - 10 - 23}[/tex]
Collect like terms
⇒[tex] \sf{3x = - 10 - 23}[/tex]
Calculate
⇒[tex] \sf{3x = - 33}[/tex]
Divide both sides of the equation by 3
⇒[tex] \sf{ \frac{3x}{3} = \frac{ - 33}{3} }[/tex]
Calculate
⇒[tex] \sf{x = - 11}[/tex]

-3(r+2)=40 whats is r in the equation , thanks :)
Answer:
r = -46/3
Step-by-step explanation:
-3(r+2)=40
Distribute
-3r - 6 = 40
Add 6 to each side
-3r-6+6 = 40+6
-3r = 46
Divide by -3
r = 46/-3
r = -46/3
While traveling to Europe, Phelan exchanged 250 US dollars for euros. He spent 150 euros on his trip. After returning to the United States he converts his money back to US dollars. How much of the original 250 US dollars does Phelan now have? Round to the nearest cent. 1 European euro = 1.3687 US dollars
Answer: Phelan now have 44.69 US dollars. of the original 250 US dollars.
Step-by-step explanation:
Given, Phelan spent 150 euros on his trip.
1 European euro = 1.3687 US dollars
So, 150 euros = 150 × 1.3687 US dollars
= 205.305 US dollars
≈ 205.31 US dollars [ Rounded to the nearest cent. ]
Initially he had 250 US dollars, now he has left (250-205.31)US dollars that is
44.69 US dollars.
Hence, Phelan now have 44.69 US dollars. of the original 250 US dollars.
Phelan now have 44.69 US dollars. of the original 250 US dollars.

Answer:
choice b d and e
Step-by-step explanation:
3(5f + 2)- f = 2(-3)
pls help asap
Answer: -6/7
Step-by-step explanation:
3(5f+2)-f=2(-3)
15f+6-f=-6 ⇔ distributive property
14f+6=-6 ⇔ subtract f from 15f
14f=-12 ⇔ subtraction property of equality (subtract 6 on both sides)
f=-12/14 ⇔ division
f=-6/7
Hope this helps!! :)
Please let me know if you have any question or need further explanation
Answer:
14f =-12
Step-by-step explanation:
3×5f+ 3×2-f = 2×-3
15f - f + 6 = -6
14f= -6

The solution to this is x ≤ 4.
So then we look at the graphs and choose the correct one.
When the sign is ≤ it's like an arrow whatever way it's pointing it goes that way. In this case it'd go the other way even though the sign is ≤, because the solution is stating 4 is greater then or equal to so it can't be less than 4. And the only option of +4 and higher is C.

150 = ?+120
Subtract 120 from each side
150-120 = ?
30 = ?
Answer:
[tex]\huge\boxed{<SUT = 30\ degrees}[/tex]
Step-by-step explanation:
According to exterior angle theorem:
The measure of the exterior angle is equal to the sum of non-adjacent interior angles.
So,
< VST = <STU + <SUT
150 = 120 + <SUT
<SUT = 150-120
<SUT = 30 degrees
The term "elevation" is often used to describe the height of a place (such as a city, a mountain, or a valley) compared to sea level. For example, the city of Houston, Texas has an elevation of 105 feet. The surface of the sea has an elevation of 0 feet. Some places are below sea level, so their elevations are negative values. Two towns have different elevations, but when the elevations are used as inputs of , they both produce an output of 25. Why do they produce the same output?
Answer:
obviously they will produce same output because the elevation of object and image will be same

Answer:
The sum of a number and 10 is equal to three times that number.
Step-by-step explanation:
Break the parts down and put them together.
The sum of a number and 10: 'g + 10'
Is equal to: '='
Three times that number: '3g'
So:
The sum of a number and 10 is equal to three times that number: 'g + 10 = 3g'

Let a,b,c,d be scalars.
In general if v and w are two vectors such that
v = <a, b>

v - w = <a-c, b-d>
so we subtract the coordinates

Explain how you find the scale factor using 2-3 sentences or showing each step. Explain using the ratio of the image length to the pre-image length.
Answer/Step-by-step explanation:
The scale factor = the ratio of the corresponding sides of the image and the preimage.
That is, A'B'/AB = B'C'/BC
The preimage is the smaller figure, given as ABCD.
AB = 3 - 1 = 2 units
BC = 4 - 1 = 3 units
The image is the larger figure, given as A'B'C'D'.
A'B' = 9 - 5 = 4 units
B'C' = 7 - 1 = 6 units

Answer:
AC =5
BC = 12
AB = 13
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
(n-1)^2 + (2n)^2 = (n+7)^2
FOILing
n^2-2n+1 + 4n^2 = n^2+14n+49
Combine like terms
5n^2-2n+1 = n^2+14n+49
Bring everything to the left
5n^2-2n+1 -n^2-14n-49 = n^2+14n+49-n^2-14n-49
4n^2 -16n -48 = 0
Divide by 4
n^2 -4n -12 = 0
Factor
( n-6)(n+2) =0
Using the zero product property
n-6 =0 n+2 =0
n=6 n=-2
Since the length cannot be negative
n=6
AC = n-1 = 6-1 =5
BC = 2n = 2*6 = 12
AB = n+7 = 6+7 = 13
Given :
Hypotenuse of right angle triangle = n + 7
Base = n - 1
Altitude = 2n
Using Pythagoras theorem :
→ ( n + 7 )² = (n - 1)² + (2n)²
→ n² + 14n + 49 = n² - 2n + 1 + 4n²
→ n² + 14n + 49 = 5n² - 2n + 1 = 0
→ n² + 14n + 49 - 5n² + 2n - 1 = 0
→ -4n² + 16n + 48 = 0
→ -4(n² - 4n - 12) = 0
→ n² - 6n + 2n - 12 = 0
→ n(n - 6) + 2(n - 6) = 0
→ (n - 6)(n + 2) = 0
As n ≠ Negative
So, n ≠ -2
So, n = 6
Hypotenuse = n + 7 = 6 + 7 = 13
Base = n - 1 = 6 - 1 = 5
Altitude = 2n = 2 × 6 = 12
So,
AB = 13
AC = 5
BC = 12

What is the (x) and (y) axis?
Answer:
and independent variable It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. and a Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
what is the doors width in simplest form
Answer:
x + 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of rectangle = 3x + 6
Width of rectangle = 4x – 1
Width of door =..?
A careful observation of the diagram shows that the door is located along the length of rectangular room.
In a rectangle, two sides are equal. Therefore,
x + door + x = 3x + 6
Making door subject of the above formula, we have:
x + door + x = 3x + 6
door + x + x = 3x + 6
door + 2x = 3x + 6
Subtract 2x from both side
door + 2x – 2x = 3x + 6 – 2x
door = 3x – 2x + 6
door = x + 6
Therefore, the width of the door is x + 6

A number is decreased by seven. Then, the new number is multiplied by 3 to get an answer of -9. What is the original number? A. -4 B. -30 C. 4 D. 30
Answer:
The answer is c
Step-by-step explanation:
You have to do everything backwards,
-9 divide it by 3 to get -3, then add seven to that answer
Answer:
C
Step-by-step explanation:
You can work backward to find out the answer!
Start with -9. Instead of multiplying by 3, you can divide.
-9/3 = -3
Now, instead of decreasing -3 by 7, increase by 7.
-3+7 = 4
You get 4, which is C!
