Answer:
27 weeks.
Step-by-step explanation:
You need to calculate the minimun common multiple between the three times.
1 week = 1^1 week
9 weeks = 3^2 weeks
27 weeks = 3^3 weeks
You take the 1 and the 3 with the biggest exponent and multiply. In this case is 1^1*3^3 = 27. So, in 27 weeks the pkanets will all be in alignment.
Answer:
4-2x=3
Step-by-step explanation:
Answer:
the solutions are c because, when we say x +7=81 that will give us 74 which is there on c
Answer:
x = 12
y = 8
Step-by-step explanation:
It's an equilateral triangle so all the sides have to be equal
2x = 24
x = 12
3y = 24
y = 8
Directly proportional means if x has a certain value, y should have the same value. but here in the graph, when x is 0, y has a value greater than 0. for x and y to be directly proportional, the line should go through 0.
