Step-by-step explanation:
Answer:-[tex]\tt{y = 4x+8x}[/tex]
First, we need to add up the x.
We know that 4+8 = 12, so
[tex]\tt{4x+8x=12x}[/tex]
Now, equating it to y,
[tex]\tt{y = 12x}[/tex]
Now, if I multiply [tex]\tt{\dfrac{1}{12}}[/tex] on both sides,
I get,
[tex]\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}[/tex]
Now, as 12 got cancelled , I got the final answer as
[tex]\boxed{\tt{x =\dfrac{y}{12}}}[/tex]

Answer:
The probability of the spinner landing on 2 is one fourth.
Step-by-step explanation:
The spinner is split into 4 equal parts labeled 1, 2, 3, 4
The probability of the spinner landing on 2 is given as:
(Possibility of it landing on 2) ÷ (Total possible outcome)
The total possible outcome is 4, because the spinner could land on 1, or 2, or 3, or 4.
It can only land on 2 once, so the possibility of it landing on 2 is 1.
Probability = 1/4

X-9y=17 find y (use integers or fractions for any numbers in the expression)
Let's see what to do buddy...
_________________________________
[tex]x - 9y = 17[/tex]
Subtract the sides of the equation minus x
[tex] - 9y = 17 - x[/tex]
Divided the sides of the equation by -9
[tex] \frac{ - 9}{ - 9}y = \frac{17 - x}{ - 9} \\ \\ [/tex]

Jaycie has 21 gallons of gas in her car and uses approximately .05 gallons of gas each mile that she drives. Which equation shows the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car? a. Y = 21x - .05 b. Y = -.05(x+21) c. Y = 21 - .05x d. Y =21 + .05x
Given:
Jaycie has 21 gallons of gas in her car and uses approximately .05 gallons of gas each mile that she drives.
To find:
The equation which shows the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car.
Solution:
We have,
Initial amount of gas in car = 21 gallons
So, y-intercept of the linear relationship is 21.
It uses approximately .05 gallons of gas each mile that she drives.
It means, the gas is decreased by .05 gallons for each mile.
So, slope of the linear relationship is -0.05. Here, negative sign represents the decrease in amount of gas.
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept or initial value.
Substitute m=-.05 and b=21 in the above equation.
[tex]y=-.05x+21[/tex]
[tex]y=21-.05x[/tex]
So, the equation [tex]y=21-.05x[/tex] represents the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car.
Therefore, the correct option is c.

Please explain how you got your answer please. it’ll help me.
Answer:
The answer is no solutions.
Step-by-step explanation:
use systems of equations!
first, rewrite both equations so that the sum or difference includes the same variable.
[tex]9-4x=6y\\-4+2x=-3y[/tex]
notice how i made sure the coefficients that have x and y respectively line up.
with this, i can cancel out the x variables by making 2, and -4 as -8 (8+-8=0).
rewrite the equation.
[tex]2(9-4x=6y)\\4(-4+2x=-3y)\\[/tex]
distribute.
[tex]18-8x=12y\\-16+8x=-12y[/tex]
now we can successfully cancel out the x variable!
[tex]18=12y\\-16=-12y[/tex]
uh oh! it seems we can also cancel out the y variables..
[tex]18=0\\-16=0[/tex]
18 is not equal to 0 and neither is -16. because of this, we can conclude there is no solution for this system of equations.
hope this helps!!

Walter and Brian each have a CD collection. • The number of CDs in Walter's collection can be represented by x. • The number of CDs in Brian's collection is 3 times the number in Walter's collection. • The total number of CDs in both collections is 144. What is x, the number of CDs in Walter's collection?
Answer:
Number of CDs in Walter's collection = x = 36
Step-by-step explanation:
x denotes number of CDs in Walter's collection.
Also, the number of CDs in Brian's collection is 3 times the number in Walter's collection.
Number of CDs in Brian's collection [tex]=3x[/tex]
Total number of CDs in both Walter's collection and Brian's collection = 144
[tex]x+3x=144\\4x=144\\x=\frac{144}{4}\\ x=36[/tex]
So,
Number of CDs in Walter's collection = x = 36

What is a transversal line?A transversal is a line that intersects two lines on the same plane at two different points. When those two intersected lines are parallel their alternate angles, interior angles and exterior angles are equal and the converse of this statement is also true.
We know when two parallel lines are intersected by a transversal their interior alternate angles are equal.
∴ (2x - 20)° = 90°
2x = (90 - 20)°.
2x = 70°.
x = 35°.

Find the equation of the line in slope intercept form
Answer:
y= 1/3x-3
Step-by-step explanation:
rise /run
-3 is the point you start
Answer:
y = 1/3x - 3
Step-by-step explanation:
First, find the slope
(3, -2)
(0, -3)
-2-(-3) = 1
3 - 0 = 3
Slope = 1/3
Now, find the y intercept
y = mx + b
-2 = 3 * 1/3 + b
-2 = 1 + b
-3 = b
Rewrite the equation
y = 1/3x - 3

5/6y-9=1/6y-5
What’s y
Answer:
y=4/6
Step-by-step explanation:
Step 1: Add 9 to both sides.
5/6y -9 = 1/6y -5
5/6y = 1/6y +4
Step 2: Subtract 1/6 to both sides.
5/6y= 1/6+4
y=4/6
If you are confused still, 5/6 - 1/6 is 4/6. Remember signs matter, because if the original equation was 5/6y -9 = -1/6y -5 the answer would be y= 4!

The posted weight limit for a covered wooden bridge in Pennsylvania is 6000 pounds. A delivery truck that is carrying x identical boxes each weighing 14 pounds will pass over the bridge. If the combined weight of the empty delivery truck and its driver is 4500 pounds, what is the maximum possible value of x that will keep the combined weight of the truck, drives, and boxes below the bridge's posted weight limit?
Answer:
The answer to x is 107
Step-by-step explanation:
If the driver and truck weigh 4500 and the bridge is can hold 6000 lbs. than there is room for 1500 more lbs. multiply 14 by 100 and get 1400, than multiply 14 by 7 and get 98. Add those to to get 1498. So the answer is x=107
