Answer:8
Step-by-step explanation:
This 1 is simple
Just subtract 7 from 15 and the answer is 8
So 15laps-7laps=8laps
We need to compute for the length of each trophy given that one trophy is 5 inches wider than the other.
Let x be the length of the first trophy.
Let x+5 be the length of the second trophy
The solution is shown below:
x + (x + 5) = 17
x + x + 5 =17
2x =17 -5
2x = 12
x = 12/2
x=6 (for the first trophy)
x + 5 = 6+5 = 11 (for the second trophy)
The first trophy is 6 inches wide while the second trophy is 11 inches wide.
There is no such real number!
a+b=-5
ab=625
a=-b-5
(-b-5)*b=625
-b^2-5b=625
b^2+5b+625=0
b=-5+-sqrt(25-2500)
This resulting in b as a complex number which means in the real numbers there is no such solutions!
63 is your answer
<u>Check:</u>
Multiply: 3 x 2 = 6
Check that it is greater than 60, less than 70: 60 < 63 < 70
