If I am not mistaken the inequality would be 45x is greater than or equal to y since the minimum would be 45 minutes a day.
Ok, here's a trick: If you're converting a smaller unit to a bigger unit in metric system, you divide by 10. When you are trying to convert a bigger unit to a smaller unit, multiply by 10. Decimeters are 1/10 of a meter, so you are going to multiply 2 by 10 because you are converting a bigger unit to a smaller unit, in which you get 20.
So your answer is 20 decimeters.
Answer:
<h3>
34, 35</h3>
Step-by-step explanation:
z - some integer
then the consecutive integer would be:
z+1, (or z-1)
the sum is 69 so:
z + z+1 = 96
2z = 68
z = 34
z+1 = 34 + 1 = 35
(or:
z + z-1 = 69
2z = 70
z = 35
z-1 = 35 - 1 = 34)
Answer:
-2 < x
Step-by-step explanation:
-6x - 16 < 2x
Add 6x to each side
-6x+6x - 16 < 2x+6x
-16 <8x
Divide by 8
-16/8 < 8x/8
-2 < x
