Isuck at math and ive been trying ri figure this out for a !
its due soon this is for mcr (math for college readiness. basically algebra)

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
