It would be 1:20 proportional to 4:5
Answer:
30
Step-by-step explanation:
All the degrees of a triangle should add up to 180 degrees.
D = F
D and F are not equal to 90.
If E = 30, D and F both equal 75.
75(2) + 30 = 180.
Step-by-step explanation:
Earth = 1trip
Mars = ½trip
If,
Mars = 1trip
Earth = ?
If more, less divides,
![\frac{1}{ \frac{1}{2} } \times 1 \\ \\ 2 \times 1 = 2 \\ therefore \: it \: takes \: two \: trips \: for \: earth \: to \: travel \: around \: the \: sun.](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%20%5Ctimes%201%20%20%5C%5C%20%20%5C%5C%202%20%5Ctimes%201%20%3D%202%20%5C%5C%20therefore%20%5C%3A%20it%20%5C%3A%20takes%20%5C%3A%20two%20%5C%3A%20trips%20%5C%3A%20for%20%5C%3A%20earth%20%5C%3A%20to%20%5C%3A%20travel%20%5C%3A%20around%20%5C%3A%20the%20%5C%3A%20sun.)
Answer:
(0, 3), (4, 9), (6, 9), (7, 17)
Step-by-step explanation:
Answer:
y = -4
Step-by-step explanation:
5 - 7y = 33 {Subtract 4 form both sides}
-7y = 33 -5
-7y = 28 {Divide both sides by (-7)
y = 28/-7
y = -4
