Let's try to make two equations.
X+Y=28
Since x is three time y, x=3y. Let's fill that in for x.
3y+Y=28
Let's solve first by combining like terms.
4y=28
28÷4=7=y
Y is 7, so that means x must be 21 since their sum is 28.
So, 21=x and 7=y.

If the cost is a function depending in the number of sections, how much will 200 sections cost?
julsineya [31]
I would say the answer is D. 7837. Since the common ratio between the x’s and y’s were are 39.5 so multiplying that times 200 gives something around 7900 so, (rounding down) the answer would be D. I really hope that helped! Also please correct me if I am wrong... thanks!

Answer:

See Below

Step-by-step explanation:

To find a unit rate, you need to have a denominator of 1 and to to do that, you can divide the numerator and denominator by the same number, in this case: 6.

30 ft / 1 sec

2) 86 mi / 5 hr

Same as above^(except dividing by 5)

17.2 mi / 1 hr

3) 83 mi / 5 hr

Same as above^^

16.6 mi / 1 hr

We can rewrite this as: 16.6 mph

4) 93 mi / 5 hr

Same as above^^^

18.6 mi / 1 hr

5) 150 mi / 4 hr

Same as above^^^^

37.5 mi / 1 hr

We can rewrite this as: 37.5 mph
