These rates are not in proportion. Juan walked faster.

Explanation:

First, we want to make these ratios to have the same denominator so we can compare the numerators. To do this, do 3x5 and 8x5 to get 40:15. Then, we do 5x3 and 14x3 to get 42:15. Now we can just compare the numbers 40 and 42, and since 42 < 40, we know Juan walked faster.

PLEASE HELP !!! WITH THESE 2 PROBLEMS !!!! 30 POINTS !!! HELP!!!

The answer to your first question would be B, because in the word problem it says that she buys 6 pots, so therefore we can eliminate A and C. We are left with B and D. Now looking at the second equation, we see that x represents the 5 inch pots, which are $12. This would mean 12x, because if she bought 1 5 inch pot, she would spend $12, and the same way, 10 inch pots are represented by y, or $15. Pretty much, multiply the number of 10 inch pots she buys by 15. Therefore the answer is B. 

Question 3 says that the sum of their ages are 105. So the first equation should be S + R = 105. The second part of the question says that Sara is 33 years younger than Rolando. This means 33 + Sara's age, represented by S, should equal Rolando's age. That is S + 33 = R. 


Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine). Thanks, it really helps! :D
