The value of b in the equation 5/2b+(-25/2) is 1.
The answer is 2 drinks left
So, we have two equations. The first one is a/b = 2, and the other one is to find the value of 4b/a. In order to solve this, let's find the value of b/a. As you can observe, b/a is the reciprocal of a/b. Therefore, b/a is also the reciprocal of 2. This means that b/a = 1/2. Now, substituting this to the second equation, the answer would be
4b/a = 4(1/2) = 2
The answer is 2.
I don't know what the answers are. Are they fill in the blanks? Like, whats up. OHHHH!! Sory. SO uh. 9. is either the solar system or radiant energy or mercury. 10. is a moon. 11. is gravity? 12. is the earth. 13. is matter or volume or mass? 14. is magnitism? 15. is volume or mass. 16. is the moon.
I don't know how to explain that. Hopefully I got most of them right.
