Step-by-step explanation:
4 + n + 7m
constants are just the numbers with no variables (letters)
so the constant is 4
coefficients are numbers multiplied by variables (letters)
so the coefficients are : 7 and 1
the error sarah made is forgetting the coefficient of n......because even if it is not written, n is the same as 1n....so basically, there is a coefficient for EVERY variable, even if its not written.
Let, the number of Lilies in each vase = x
Then, expression would be: 10(15+x)
150+10x
So, final answer is 150+10x
Where, x = number of lilies.
Hope this helps!

Step-by-step explanation:
A supplementary angle is equal to 180 degrees. So subtract 96.7 degrees from 180. 180-96.7= 83.3 degrees
Your answer is 83.3 degrees.
Answer:
During halftime of a basketball game, a sling shot launches T-shirts at the crowd. A T-shirt is launched with an initial upward velocity of 78 feet per second. The hight of the t-shirt (h) in feet after t seconds is given by the function h=-16t^2+78t+5. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is its maximum height?

Answer:
If they start moving towards each other simultaneously it will take 5 hours to meet.
Step-by-step explanation:
Motorcycle:
Distance = 540 miles
Speed = 48 mph
Time taken = Distance/Speed = 11.25 hours.
Car:
Distance = 540 miles
Time taken = 11.25 -2.25 = 9 hours.
Speed = Distance/Time = 540/9 = 60 mph
If they start moving towards each other simultaneously, they will travel a combined distance of 540 miles and Let the time be t hours.
We have
48 t + 60 t = 540
108 t = 540
t = 540/108 = 5 hours.
If they start moving towards each other simultaneously it will take 5 hours to meet.
