6th grade math help me please ! :))
Stells [14]

Answer:

1,825 days

Step-by-step explanation:

730 / 2 = 365 (one year, or the number of days a single revolution around the sun takes)

Now just multiply by 5

[365 · 5 = 1,825], thus 1,825 days are the duration of 5 revolutions.

The problem could also be initially expressed as:

x = (720/2) · (5) with x representing the missing value

Ilia_Sergeevich [38]

Answer:

14, 22

Step-by-step explanation:

x+y = 36

2×x - y = 6

=> x = 36 - y

=> 2×(36 - y) - y = 6

72 - 2y - y = 6

-3y = -66

3y = 66

y = 22

=> x = 36 - 22 = 14
