There are boys and girls in a class. if the number of girls is multiplied by two and added to the number of boys in the class, the sum is 30. if the number of girls is multiplied by two and the number of boys in the class is subtracted from it, the result is 6. how many boys are in the class?

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

the ratio would be 4: 3, the four being for jackson, and the three being not for him.
