Answer:
Step-by-step explanation:
We'll d the sales tax last.
So, assumedly 1-200 will cost that base 21.50 regardless, so if we say the first 200 is 21.50 that means the remaining 200 will get the other price. The other price is 10 dollars per 100. So 200 is 100 twice, so that's 10 dollars twice, which is 20.
This leaves 41.50 as the base price. Now to find the sales tax you multiply the base price by the tax percentage in decimal form. 6% is .06 in decimal form. So you do 41.50*.06 = 2.49. That is how much is being added. so now the full price is 41.50+2.49 = 43.99.
Anther way to find sales tax is this formula b(1+t) where b is the base price and t is the tax in decimal form. So for this you could have done 41.50(1+.06).
-- A rhombus is always a parallelogram and a quadrilateral.
A rhombus can also be a square, but not all of them are.
-- A rectangle is always a parallelogram and a quadrilateral.
A rectangle can also be a square and a rhombus, but not all of them are.
-- A parallelogram is always a quadrilateral.
A parallelogram can also be a square, a rectangle, or a rhombus, but not all of them are.
-- A quadrilateral can be a square, a parallelogram, a rectangle, and a rhombus.
But not every quadrilateral needs to be any one of these things.
<em>However . . .</em>
-- You can definitely be sure that every square is always a quadrilateral,
a parallelogram, a rectangle, and a rhombus.
All four choices apply to a square, and should be selected.
Answer:
its about 2
Step-by-step explanation:
Simplifying
7(3x + 5y) = 0
(3x * 7 + 5y * 7) = 0
(21x + 35y) = 0
Solving
21x + 35y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-35y' to each side of the equation.
21x + 35y + -35y = 0 + -35y
Combine like terms: 35y + -35y = 0
21x + 0 = 0 + -35y
21x = 0 + -35y
Remove the zero:
21x = -35y
Divide each side by '21'.
x = -1.666666667y
Simplifying
x = -1.666666667y
Answer:
I don’t know much about the second part but the number 3 is being multiplied by is 7. 3x7=21, and than you add 5 giving you 26. Ohhhh now I see the equation is 3 times x+5=26.
