Step-by-step explanation:
Given
x - 6y = 18
To find the x- intercept let y = 0 in the equation and solve for x, that is
x - 0 = 18
x = 18 ← x- intercept ⇒ (18, 0 )
To find the y- intercept let x = 0 in the equation and solve for y, that is
0 - 6y = 18
- 6y = 18 ( divide both sides by - 3 )
y = - 3 ← y- intercept ⇒ (0, - 3 )
Check out the image attachment for one way to draw this problem out. Notice how angles AEC and DEB are vertical angles, so that means they are congruent angles
(measure of angle AEC) = (measure of angle DEB)
6x + 20 = 10x
6x + 20-6x = 10x-6x ... subtract 6x from both sides
20 = 4x
4x = 20
4x/4 = 20/4 ... divide both sides by 4
x = 5
The value of x is 5.
Let's check the answer
6x + 20 = 10x
6*5 + 20 = 10*5 ... replace every x with 5
30+20 = 50
50 = 50
We have confirmed the answer.
The answer is x=5. I've included the work in the picture attached.
Answer:
Story 1
Step-by-step explanation:
For story 1:
Lin gave 12 flyers to 3 people. She took the remaining flyers (90 - (12*3)) and divided then into groups of 3 to give to the volunteers. That would be 3(12) + 3(y) = 90 which is also 3(12+y) = 90.
For story 2:
The equation would be "3(y) + 12 = 90" and not "3(12+y) = 90"
