(1 point) An instructor gives his class a set of 15 problems with the information that the next quiz will consist of a random selection of 7 of them. If a student has figured out how to do 8 of the problems, what is the probability the he or she will answer correctly

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

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
