Fill in the blank: In a school in Florida, 40% of the students stay in the school's dormitory and 60% stay with their families. The school
records show that 30% of the students living in the dormitory and 20% of the students living with their familles obtain AS
on exams.
If a student chosen at random from the school receives As, the probability that the student lives in the school dormitory is

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

is there a picture

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
