Step-by-step explanation:
you did not even try a calculator to find the result ?
64 is 8×8 or 8².
so, sqrt(64) = 8.
similarly for 4 :
4 is 2×2 or 2².
so, sqrt(4) = 2
so,
sqrt(64)/ sqrt(4) = 8 / 2 = 4
so, d. is the right answer.
Answer:b
Step-by-step explanation:
Answer:
infinitely many solutions
Step-by-step explanation:
Let's eliminate the fractional coefficient in the first equation by multiplying that equation by 4:
4y = 6x - 4
The second equation can be rewritten as 4y = 6x - 4, so the two equations are actually identical. They have infinitely many solutions.

solve for "w", to find the wind's speed rate,
so hmmm what's the plane's rate? well 420 - w = r :)
