Answer:
1)
2/5 ≠ 10/15= 2/3 not equivalent
3/7 ≠ 6/7 not equivalent
9/7 = 1 2/7
= 9/7 equivalent
2)
a) 50/75 = 25*2/25*3= 2/3
b) 65/105 = 5*13/5*21= 13/21
c) 18/81 = 9*2/9*9= 2/9
Answer:

Step-by-step explanation:
Let
x ----> the numbers of trophies you can buy
y ----> the numbers of medals you can buy
we know that
The term "at most" means "less than or equal to"
so
The number of trophies multiplied by $12 plus the number of medals multiplied by $3 must be less than or equal to $60
The inequality that represent this situation is

Answer: 494991
Step-by-step explanation:
Hi! So by looking at your graph, you want to find the slope. First you want to find to points and find the distance between the two. I’ll use the points (-8,4) and (-2,2). Starting at (-8, 4), move down 2 and right 6. This shows that your slope will be -2/6 (further simplified to -1/3)?
Now, looking at each equation given to you in standard form, which will have a slope of -1/3? Your first answer, 2x+6y = 8, has a slope of -1/3, with a y-intercept value of 4/3 (or 1.5). If you look back at your graph again, you can see that the y-intercept is 1.5, so your answer will be A. :)
