Answer:
18
Step-by-step explanation:
the ratio of blue eyed students to non-blue eyed students is 7 to 12,
Total ratio = 7+12=19
Total student= 50 students
Ratio of blue eyes student= 7/19 ×50
=18.4
Hence, there are approximately 18 students with blue eyes.
Answer:
(3^2) - n
Step-by-step explanation:
For this problem we will take it step by step to build the expression:
raise 3 to the 2nd power
= 3^2
then find the difference of the result and n
= (3^2) - n
Hence, your final expression should be (3^2) - n.
Cheers.
Answer: They do it to a lot of people. I don't know why though
Step-by-step explanation:
Multiply the first equation by 7 and the second equation by 2, and then add.
Step-by-step explanation:
2f - 5g=-9
-7f + 3g=4
To eliminate any variable , we need to make the coefficients same with different sign and add it
the coefficient of 'f' in first equation is 2
the coefficient of 'f' in second equation is -7
We already have different sign so we make the coefficients same
To make the coefficient same , we multiply the first equation by 7 and second equation by 2
So equation becomes
14f - 35g = -63
-14f + 6g = 8
Now when we add both equations, 'f' gets cancelled
-29g = -55
My life is not linear. Time is not constant. My life (and time included) is just a series of times that do not run parallel to each other. Instead, they drift further or closer as a function of velocity and curvature of space time.
