First you should simplify:
2m - 2/10 * 2*m = 2m - 2/5m = 10/5m - 2/5m = 8/5m
and now you can say: 8(m/5) = 8/5m
so they are equivalent :)))

Answer:
The individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
Step-by-step explanation:
First we have to find 2 equations to express the problem
x = value of each item
y = total amount of money
3x = y
4 ( x - 2.25 ) = y
we replace the y by (3x) in the second equation and obtain the value of x
4 ( x - 2.25 ) = y
4 ( x - 2.25 ) = 3x
4x - 9 = 3x
4x - 3x = 9
x = 9
9 - 2.25 = 6.75
this means that the individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
If you subtract the one dirty car you get 5 cars only cleaned.
Hope it helps
Answer:
Trigonometric ratio is the special measurements of a right triangle. There are three basic trigonometric ratios which are sine , cosine , and tangent.
Step-by-step explanation:
What is sine? The sine of an angle x is the length of the opposite side.
What is cosine? The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.
What is tangent? The tangent of an angle is the length of the opposite side
Tangent and sine are very closely related and easily mixed up. Be carful with your calculations for the most accurate answer.
