Answer:
The number is 0.2
Step-by-step explanation:
Write an equation for it:
Say that the number was called x
2(x +8) =16.4
Brain added 8 to the number (x) and then doubled it which is the 2
Times out the brackets 2x + 16 = 16.4
Take away 16 from both sides
2x = 0.4
0.4 / 2 = 0.2
Answer:
-4
Step-by-step explanation:
1. Use the distributive property to get 6x + 36 = -2x + 8 + x
2. Combine like terms 6x + 36 = -x + 8
3. Subtract 36 on both sides. 7x + 36 = 8 > 7x = -28
4. Divide by 7
-28/7 = -4 x=4
No.
So, there are 1000 milligrams in one gram, making the 4000 mgs equal to 4 grams.
There are 1000 grams in one kilogram, so 4 kilograms is equal to 4000 grams.
4000 =/= 4
So, 4 kilograms and 4000 milligrams are not equal.
So their are 60 min in an hour. you multiply 60 min times 6 (hours). you get 360 min. Then you divide that by 90 min and you get 4
Answer it orbits 4 times
