9a-4y
because -5y and a positive Y combine to a -4y
When reflection goes about y-axis, the x coordinate changes into its opposite.
(-4,5)---->(4,5)
(-2,2)----->(2,2)
2 miles = 10560 ft.
3333 yards = 9999 ft.
I'm presuming this is supposed to be a ratio so:
10560/9999
or
320/303
Answer:
35 minutes
Step-by-step explanation:
The is calculated using the Subtraction operation
The number of minutes longer the team practiced today than yesterday =
Number of minutes they practiced today - Number of minutes they practiced yesterday
Number of minutes they practiced today = 3 hours 15 minutes
Number of minutes they practiced yesterday = 2hours 40 minutes
The number of minutes longer the team practiced today than yesterday =
3 hours 15 minutes - 2hours 40 minutes
= 35 minutes
Therefore, the team practiced 35 minutes longer today than yesterday
6x - 5y = 5
3x + 5y = 4
If the left sides are equal to the right sides then if we add left side of first equation to left side of the second one and right side of the first euation to right side of the second one they still would be equal
6x - 5y = 5
<u> 3x + 5y = 4</u>
9x +0y = 9
9x = 9
x = 1
