If 3x + 6 = 21, what does x + 2x plus 2 equal?
Answer:
x+2x+2=17
Step-by-step explanation:
I'm assuming that's what you're asking, so here is the answer explanation.
3x+6=21
3x=15
Hence, x=5
Apply x=5 to x+2x=2
5+10+2
=17

Answer:
z = [tex]\frac{4x}{3y}[/tex]
Step-by-step explanation:
x = [tex]\frac{3yz}{4}[/tex] ( multiply both sides by 4 to clear the fraction )
4x = 3yz ( isolate z by dividing both sides by 3y )
[tex]\frac{4x}{3y}[/tex] = z
12y=360 solve for y
Answer:
30
Step-by-step explanation:
divide both sides by 12 to find y
12y / 12 = y
360 / 12 = 30
therefore y = 30
how what is 3/56 as a percentage
Answer:
5.4% rounded to the tenths place.
Reasoning:
To convert 3/56 to a percentage, multiply the decimal version of 3/56 by 100.
Estimated, 3/56 as a percentage is 5.4%
1/3(x-6)=16
Please help me out
Answer:
[tex] \frac{1}{3} (x - 6) = 16) \times 3 \\ x - 6 = 3 \times 16 \\ x = 48 + 6 \\ \color{yellow} \boxed{ x = 54}[/tex]

6(x + 1) = -2(3x + 9)
Answer:
x=-2
Step-by-step explanation:
6(x + 1) = -2(3x + 9)
Distribute 6 and -2.
6x+6=-6x-18
Move the variable to the left-hand side and move the constant to the right and change their signs.
6x+6x=-18-6
Collect like terms.
12x=-24
Divide both sides of the equation by 12.
x=-2
Hope this helps :)

There are ten people lined up and they are lined up from shortest to tallest. determine the order of the people from the following clues
-bill is taller than will. will is taller than violet
-violet is taller than Ted. Cody is taller than violet but shorter than will
-sam is standing between sal and Todd, who is shorter than Bill but taller than Sam
-van is standing between Bill and Ian, who is standing next to Todd
-there are seven people standing between van and Ted.
NAMES
Ted, Bill, Ian, Van, Cody, Sal, Violet, Sam, Will, Todd
1 being shortest, 10 being tallest.
PLEASE PROVE YOUR WORK :)
9514 1404 393
Answer:
Ted-1, Bill-10, Ian-8, Van-9, Cody-3, Sal-5, Violet-2, Sam-6, Will-4, Todd-7
Step-by-step explanation:
The key to this seems to be "there are seven people standing between Van and Ted." This means either Van or Ted is at one end of the line. There will be one person standing at the end beside whichever one of these is not at the end of the line.
Then "Van is standing between Bill and Ian, who is standing next to Todd" tells you it is not Van who is at the end, but it is Bill. This tells you the four tallest people in decreasing order are Bill, Van, Ian, and Todd. We know Bill is not the shortest, because Bill is taller than Todd. That means Ted is the shortest.
The next shorter people than Todd are Sam and Sal (Sam is between Sal and Todd).
At this point we know the order of 7 people: the 6 tallest, and the shortest. The remaining 3 are Violet, Cody, and Will. Since "Cody is taller than Violet, but shorter than Will," we know the final order, shortest to tallest, is ...
Ted, Violet, Cody, Will, Sal, Sam, Todd, Ian, Van, Bill

Hurry for Brainlist =Accurate Answer
Step-by-step explanation:
the second line has to be parallel (but not identical), so that the 2 lines do not cross each other, do not have any point in common.
that means it must have the same slope but a different y-intercept.
the line in the graph goes through the origin (0, 0), which makes the y-intercept = 0 (the y value when x = 0).
and we see that the points with integer coordinates seem to be e.g. (3, -2).
so, for the slope (y difference / x difference between 2 points) we use this point and the origin.
x changes by +3 (from 0 to 3).
y changes by -2 (from 0 to -2).
so, the slope is -2/3. and it is always the factor of x.
let's look at the answer options :
2x + 3y = 0
3y = -2x
y = (-2/3)x
this is the identical line, so it is wrong !
2x + 3y = 6
3y = -2x + 6
y = (-2/3)x + 2
the same slope and different y-intercept.
this is the correct solution !
2x - 3y = 9
-3y = -2x + 9
y = (2/3)x - 3
wrong slope. so it is wrong !
y = 3x + 2
wrong slope. so it is wrong !
Help me do this plz
Answer:
10.25
Step-by-step explanation:
Using the pythagorean theorem
13^2 = 8^2 + (ML)^2
169 = 64 + (ML)^2
Subtract 64 from both sides
105 = (ML)^2
Take the square root of both sides
10.25 = ML
Rewrite x2 - 8x + 13 = 0 in the form (x -a)2= b, where a and b are integers, to determine the a and b values.
O a = 4 and b = 3
O a = 3 and b = 2
O a= 2 and b = 1
O a = 1 and b = 4
Answer:
a =4 and b= 3
Step-by-step explanation:
Stare at it for a bit. You have the squre of x, then(ignoring the minus sign) 2 times x times 4. What's left is the square of 4, which is 16; you have 13, you are 3 short. Let's add them to both sides:
[tex]x^2-8x+13+3=3 \rightarrow x^2-8x+16 = 3\\(x-4)^2 = 3[/tex]
so a =4 and b= 3
Help finding surface area
Answer:
471.23 km²
Step-by-step explanation:
This is a cylinder.
Here's the formula to the the surface area of a cylinder.
[tex]Surface\:\:Area\:\:\:= 2\pi r(r+h)[/tex]
They have given the the diameter of the circle .
There fore we have to find the radius .
d = 2 r
10 = 2 r
5 km = r
Let's find the Surface area now.
[tex]2\pi r(r+h)[/tex]
[tex]2 *\pi *5(5+10)[/tex]
[tex]10\pi *15[/tex]
[tex]150 \pi[/tex]
471.23 km²
Hope this helps you.

A pancake recipe calls for 4 cups of flour and 3 cups of milk. Does a recipe calling for 2 cups of flour and 1.5 cups of milk use the same ratio of flour to milk?
Answer:
I think the answer is Yes
Step-by-step explanation:
For example, 2 cups of flour can equal 4 cups of flour by multiplying by two. So 1.5 cups of milk, you multiply by two and it is equivalent to 3 cups of milk. So in the end, it is equal and it's basically half of the pancake recipe. Hope it helps!
