You would change the whole number to a fraction by putting it over 1 and make the mixed number an improper fraction by multiplying the whole number part of the mixed number by the denominator and then and the numerator
6 + 4x = 156
4x = 150
X = 37.5
now, this is pretty much the same as the one before it with Jaime, so I'll do this without much fuss.
recall d = rt.
a = Alfonso's rate
with the wind his speed is a + 5, against it is a - 5, 60 miles with it and 30 miles against it, all in the same time of t hours.

0.93
Step-by-step explanation:
u have to add them all and divide by 12. then u add all of them but the outlier and divide by 11. then u subtract.

Answer: E) 8i</h3>
Explanation:
By definition, i = sqrt(-1)
Which means,
sqrt(-64) = sqrt(-1*64)
sqrt(-64) = sqrt(-1)*sqrt(64)
sqrt(-64) = i*sqrt(8^2)
sqrt(-64) = i*8
sqrt(-64) = 8i
On the second line, I used the rule sqrt(x*y) = sqrt(x)*sqrt(y). The fourth line used the rule sqrt(x^2) = x when x is nonnegative.
