I would say that m CD would be (A)74).
hope this helps
The t-coordinate of the solution to this system represents C. the time at which the ball and the dog's mouth are at the same height.
<h3>
How to explain the coordiante?</h3>
A coordinate time scale is a time standard designed for use as the time coordinate in the calculation.
When Laurie throws a tennis ball toward her dog from a height, the t-coordinate of the solution to this system represents the time at which the ball and the dog's mouth are at the same height
The complete question is:
Laurie throws a tennis ball toward her dog from a height of 4.5 ft. The initial vertical velocity of the ball is 18 ft/s. At the same time as Laurie throws the ball, her dog jumps with an initial vertical velocity of 21 ft/s. When the dog jumps, its mouth is 1.5 ft above the ground. What does the t-coordinate of the solution to this system represent?

Answer:
5m+41n
Step-by-step explanation:
4(2m+5n)-3(m-7n)
8m+20n-3m+21n
8m-3m+20n+21n
5m+20n+21n
5m+41n

Answer:32
Step-by-step explanation:
Since 5 dark colors are equal to 8 light colors, see how many times 5 goes into 20. 20/5=4. So now multiply 8 with 4. 8x4=32.
