Multiply the whole thing by (3a/3a) to get (6a)/(3+1)=6a/4=3a/2, so ya, 2nd is correct
Its 64
You do whats in the parenthesis first -
(5 x 11) + 9 = (55) + 9 = 55 + 9 = 64
Can you give me brainliest please haha
Answer: 375 calories
Form a proportion. Let x be the number of calories burned on a 5 km run.
![\frac{120}{1.6} = \frac{x}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B1.6%7D%20%3D%20%5Cfrac%7Bx%7D%7B5%7D)
Solve for x by cross-multiplying.
![1.6x = (120)(5)\\1.6x = 600\\x = 375](https://tex.z-dn.net/?f=1.6x%20%3D%20%28120%29%285%29%5C%5C1.6x%20%3D%20600%5C%5Cx%20%3D%20375)
3 + 5 - 7 = 1
1, Hope this helps!
