They will both be there on day 84
If you were solving a system of equations and you come to a statement like 4 = 4 ( or 0 = 0 or 1 = 1 etc ) than you know that:
D ) There are infinitely many solutions.
The one with (1, 10) and (1, 15) because in a function the same x value cannot equal different y values
Step-by-step explanation:
If you start at the 1 whole and turn the one into ten and count backwards to C, you'd go back three lines, so the answer would be: 0.7
Angles ABD and DBC are supplementary. They are also a linear pair because they share a ray. Supplementary angles add up to equal 180, as do linear pairs. Therefore, from our picture, 7x + x - 4 = 180. 8x = 184. Therefore, x = 157. 157-4 = ∠DBC, so ∠DBC = 153.
