Step-by-step explanation:
The ratio cosine tell us that
- In a right angled triangle, the cosine of an angle is the side adjacent to the angle divided by the hypotenuse of the triangle.
In other words,
The side adjacent to angle a is 9. The hypotenuse is 41.
So
Tell me if you're still confused.
2.65x + 2.50 = y
step by step explanation:
2.65 is how much for each mile, and the variable, x, represents the number of miles of the trip. so, we would do 2.65x to find out how much money you have to pay for the amounts of mile.
next, you would have to add the initial fee, which is 2.50. so 2.65x+2.50.
lastly, y represents the total cost of the trip. so, 2.65x + 2.50 = y

Answer:
x = 0
Step-by-step explanation:
You can eliminate parentheses and subtract 50.
5(2x +10) = 50
10x +50 = 50 . . . . use the distributive property
10x = 0 . . . . . . . . . subtract 50 from both sides
x = 0 . . . . . . . . . . . divide by 10

<em>Check</em>
5(2·0 +10) = 50
5(10) = 50 . . . . true
A. Because you would have to subtract C to isolate a by itself
