Answer:
18
Step-by-step explanation:
There are selveral ways of doing this
1. add all the numbers together so 2+10+6=18
or
2. 3x= (2+10) +6
(12)+6
18
3x=18
/3. /3
x=6
then 3(6)
therefore equalling 18 as well

What is the constant proportionality?
Answer:
The constant of proportionality is the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX. ... The constant of proportionality does is, the value of Y is dependent on how the given value of X is effected by the constant of proportionality.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Constant of proportionality means slope which can be represented as y=mx+b, y=kx and a ton of other stuff I don't know.
But lets take it as y=kx because it's easier. Constant of proportionality/slope is k so its C, 5.5.

Please help!!!! I need to pass this class!!
Answer:
x is approximately 69.39 degrees.
Step-by-step explanation:
To find x in this triangle, we can use the sin rule:
[tex]\frac{a}{sin(A)} =\frac{b}{sin(B)}[/tex]
The corresponding angle for each length is the one that lies directly opposite it. E.g. if 3.5 was our length 'a', then 55 degrees would be our angle A.
So let's take 3.5 and 55degrees as our length and Angle A, and 4 and x degrees as our length and angle B as we are trying to solve for x.
This would give us the following equation:
[tex]\frac{3.5}{sin(55)} =\frac{4}{sin(x)} \\[/tex]
Since we are solving for an angle, it will be easier to rearrange the equation if we have it as the numerator, so we can flip the fractions to make it easier. It will still be equal as we are looking for the ratio.
[tex]\frac{sin(55)}{3.5} =\frac{sin(x)}{4} \\[/tex]
From here let's isolate the sin(x) by multiplying by 4 and solving the values we have so far:
[tex]\frac{4 sin(55)}{3.5} =sin(x)\\\frac{3.2766}{3.5} =sin(x)\\0.936=sin(x)[/tex]
Now the final step is to use inverse sin to cancel the sin so we just have x:
[tex]sin^{-1} 0.936=x\\x=69.39[/tex]
x is approximately 69.39 degrees.

Explain what a rigid motion is and why it is important
Answer:
rigid motion preserves the original shape and size of the figure—so the new figure after the rigid motion and the old figure before it would be congruent.

Am I right?
OK i dont know what time it is for you so its 5:40 am but here another question.
I have $40.50
If i went to a store and got 3 boxes of popcorn ( $15.99)and 3 milk jugs ($12.99).Then get a pack of gum ( $1.99).Plus tax ( $4.99) add to everything.Hint plus all money then add $4.99 three times.
Answer:
Question wasn't specific enough but I believe the cost=$93.92
Step-by-step explanation:
15.99*3=47.97
12.99*3=38.97
plus 1.99 and 4.99, add them all together
47.97+38.97+1.99+4.99=93.92
The formula for the remaining volume of fuel in a cars tank is I - E • D, where I is the initial volume of fuel, E if the fuel efficiency, and D is the distance traveled. Carson drove a distance of 120 kilometres. He initially had 30 litres of fuel, and his car's fuel efficiency is 100 cubic centimetres per kilometer. What calculation will give us the estimated volume of fuel left in Carson's tank by the end of the drive, in litres? a)30-100/1000 • 120 b)30•1000-100•20 c)30/1000 -100•120 d)30-100•1000•120
Answer:
a)30-100/1000 • 120
Step-by-step explanation:
Given:
Remaining volume of fuel in a cars tank = I - E • D
where,
I = initial volume of fuel
E = fuel efficiency
D = distance traveled.
Carson
I = 30
E = 100
D = 120
Estimated volume of fuel in Carson's tank = I - E • D
= 30 - 100/1000 * 120
a)30-100/1000 • 120
Answer:
A (30-(100/1000)x120)
Step-by-step explanation:
I is a volume quantity, D is a distance quantity, and E is a rate measured as volume/distance.
So ExD gives us volume quantity.
Distance units are consistent (kilometers) but the volume units of E are inconsistent with those of I and the desired answer.
Let's convert E to liters per kilometer. We will use the fact that there are 1000 cubic centimeters per liter.
You get: 30 liter - 100/1000 liters/kilometer x 120 kilometers
In conclusion, this is the calculation that will give us the estimated volume of fuel that remains in Carson's tank by the end of the drive, in liters:
30-100/1000x120.

Answer:
measure of angle ROQ is 41.5º
Step-by-step explanation:
That little curved line inside the angle POR and angle ROQ means they are congruent, or have congruent angles. So, we have two of the same angles, which we can represent with the same variable: x.
114-31= 83
83=2x
83/2 = 41.5
x=41.5
jjsndbddjijfnfbfbdhjdidoxo29294847
Find the value of x. Then find the angle measures of the polygon.
Please help me as soon as possible, it would be great if you gave me an explanation!
For number 20:
Because a triangle is 180 degrees, we will equal all the angles we know to that. So, this is how we will write our equation:
Solve for x:
60 + x + 20 + 3x = 180
4x = 100
x = 20
Using 75, you can find the angle measure by plugging 75 where x is present in the angle measures. For example:
x = 20,
20 + 20 = 40
3(20) = 60
-
For number 21:
The shape shown is basically two triangles, so 180 x 2 is 360. Again, same procedure. Add all known angle measures and make an equation where they all equal 360.
Solve for x:
x-5+x+35+1.4x+x=360
x = 75
By isolating x, you should get an answer of 75. Now, plug that into each of the equations:
x = 75
75 + 35 = 110
75 - 5 = 70
1.4(75) = 105

If f(x) = -x^2 +5z and g (x) = 2x-4 find
Answer:
1) x=√−y+5z or x=−√−y+5z
2) g=2x-4/x
Step-by-step explanation:
explanation for first problem:
Let's solve for x.
y=−x^2+5z
Step 1: Flip the equation.
−x^2+5z=y
Step 2: Add -5z to both sides.
−x^2+5z+−5z=y+−5z
−x^2=y−5z
Step 3: Divide both sides by -1.
−x^2
−1
=
y−5z
−1
x2=−y+5z
Step 4: Take square root.
x=√−y+5z or x=−√−y+5z
explanation for problem 2:
Let's solve for g.
gx=2x−4
Step 1: Divide both sides by x.
gx/x = 2x-4/x
g=2x-4/x

What is N + (n+2) when N = 62 and n = 64
twelve is no more than the sum of -1.5 times a number w and 4
Answer:
w < -5.33333
Step-by-step explanation:
Step 1: Write inequality
12 < -1.5w + 4
Step 2: Solve for w
Subtract 4 on both sides: 8 < -1.5wDivide both sides by -1.5: -5.3333 > wRewrite: w < -5.33333Here we see that any value smaller than -5.3333 will work.

A store has all board games on sale for 25% off the
regular price. A checker set has a sale price of $12. It is then moved to a clearance table where every item is discounted 40% off its regular price. What is the
clearance price of the checker set?
Answer:
$7.20
Step-by-step explanation:
We'll need to find out 40% of 12 then subtract that amount because we're still paying 60% of the original price.
Change the percent to a decimal: 0.4
Multiply the sale price and the decimal
12 · 0.4 = 4.8
Subtract 40% of the price from 12
12 - 4.8 = 7.2
The clearance price of the checker set is $7.20
Answer:
If both the board games discount and the clearance discount affect the item, this means it is 65% off. 65% of 12 is 7.8, therefore we subtract that amount from 12 and get 4.2, or $4.20.

Step-by-step explanation:
4 units right means x+4. now find the coordinates and add 4 to each coordinate's x.
3 units down means y-3. now find the coordinates and take 3 from each coordinate's y.
