To prove that it is a parallelogram, remember that the definition of a parallelogram is a quadrilateral with two pairs of parallel sides. Therefore, one way to prove it is a parallelogram is to verify that the opposite sides are parallel. From algebra, remember that two lines are parallel if they have the same slope.

To find the total amount Dave and Mel paid, apply the taxes to their initial purchases.
Dave paid $15 for a baseball. There was an 8% tax added to this total afterwards. To add the tax to the amount Dave paid, convert the percentage into a decimal:
Multiply the cost of the baseball by this decimal to find the tax:
Add the tax onto the cost:
Dave paid $16.20 in total for the baseball.
Mel paid $20 for a football. There is an 8% tax added to this total afterwards. We already have the decimal for an 8% tax, so we can multiply the football's cost by the decimal:
Add the tax onto the cost:
Mel paid $21.60 for the football.
Subtract the bigger cost by the smaller cost:
There is a
$5.40 difference between Dave's and Mel's purchases.
Answer:
We want to solve the equation:
x*6 - 9 = 7
To solve this we need to isolate x in one side of the equation.
First, we need to add 9 in both sides of the equation to get:
(x*6 - 9) + 9 = 7 + 9
x*6 - 9 + 9 = 16
x*6 = 16
Now we can divide both sides by 6, to get:
x*6/6 = 16/6
x = 16/6 = 2.66
This is not an integer as the question wants, so i only can suppose that the question is incorrectly written.
If the equation was something like:
x/6 - 9 = 7
Using the same approach than before (the only difference is that we multiply both sides by 6 in the second step), we would get:
x/6 = 7 + 9 = 16
x/6 = 16
x = 16*6 = 96
x = 96
Which is an integer, so i suppose that the actual equation is "x/6 - 9 = 7" instead of "x*6 - 9 = 7"
Answer:
re write this correctly..
(200 x 3) + 900
then do the steps in order.
200 x 3 = 600
add the extra 900 etc
600 + 900 = 1500
