Which expressions are equivalent to 1/3+8d+5/7? check all that apply

answer:

the answer is a) under or secondary

step-by-step explanation:

let's have in mind:

f(n) = a1 + (n - 1).r

r = a2 - a1

r = 10 - 3

r = 7

so,

f(n) = a1 + (n - 1).7

f(n) = 3 + (n - 1).7

f(n) = 3 + 7n - 7

f(n) = 7n - 4

answer:

b. 78o and 102o

step-by-step explanation:

supplementary angles add to 180 degrees

a. 100o and 90o

100+90 = 190   no

b. 78o and 102o

78+102 = 180   yes

c. 54o and 146o

54+ 146 = 200 no

d. 12o and 78o

12+ 78   90     no   these are complementary

answer:

the answer would be 0.12

(move the decimal 2 places to the left)
