Write the equation of a line parallel to the line with the equation
a. 3x- 6y=12 b. 5x-y=10

and

Step-by-step explanation:

The big thing to remember with this is that parallel lines have the same slopes. We can isolate the y-variable in both of these to get the slope-intercept form, which just makes it easier to see the slope.

a. 3x-6y=12

Now that we know the slope, we can have any y-intercept except for the original one, they just need to have the same slope. So an equation that could work is .

b. 5x-y=10

This equation can be solved in the exact same way.

Parallel line:

Again, it does not matter what the y-intercept is, they just can't have the same one. The slopes have to be the same.

Hope this helps!

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
