Using proportions, it is found that $1,225 is earned from nachos.
- This question is solved by <em>proportions</em>, using a rule of three.
- The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
- When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?
The <em>rule of three</em> is:
$1,540 - $1,330
$1,672 - $x
Applying line multiplication:
$1,225 is earned from nachos.

Answer:
for adult tickets 90 and for children’s tickets 30
Step-by-step explanation:
because 90(18) = 1,620 and 30(12) is 360 and when you add up 1,620 + 360 you will get the total which is $1980
Also i just took the test on k12 and got it right and i hope this helps!
Answer:
Step-by-step explanation:Step 1: Simplify both sides of the equation.
−2+3y=y−2−4y
−2+3y=y+−2+−4y
3y−2=(y+−4y)+(−2)(Combine Like Terms)
3y−2=−3y+−2
3y−2=−3y−2
Step 2: Add 3y to both sides.
3y−2+3y=−3y−2+3y
6y−2=−2
Step 3: Add 2 to both sides.
6y−2+2=−2+2
6y=0
Step 4: Divide both sides by 6.
6y

Answer:
y=0
Answer:
y = x - 2
Step-by-step explanation:
Using any two points to find the slope. I will using (3, 1) and (7, 5)
Slope = (change in the y values)/(change in the x values)
Slope = (5 - 1)/(7 - 3) = 4/4 = 1
Next find the y -intercept "b", using the table to find the value of y when x is zero. That point is (0, -2) . So the y-intercept ("b") is -2
or use one of the point (7, 5) and substitute into the slope- intercept formula and solve for "b'
y = mx + b
5 = 1(7) + b
5 = 7 + b
-2 = b
Write the equation in the slope-intercept form y = x - 2
Answer:
Step-by-step explanation:
Since both the triangles are similar, their sides will be in proportion. As one side is getting doubled, by SSS test of similarity, all the other sides will get doubled as well.
As the perimeter of a triangle is sum of its sides, the doubling of all sides will result in doubling of the perimeter.
Hence, perimeter of 2nd triangle = 14 cm.
