Ok so 7:12 is already in it's simplest form because there is nothing that can go into both 12 and 7 (which is a prime number). So in fraction form it would be 7/12
<span>8:10, so a number than can go into both 8 and 10? 2 can go into 8 4 times, and 10 5 times. So the fraction would be 4/5 which is in simplest form (5 is prime) </span>
<span>25:50, again, what can go into both 25 and 50? 5 can. 5x5= 25 5x10=50. The fraction would be 5/10, which can be reduced to 1/2. </span>
<span>80:60, 10 can go into both of them. 8/6 which can be reduced to 4/3 (2 goes into 8 4 times and 2 goes into 6 3 times) </span>
<span>78:780, 2 can go into 78 32 times and can go into 780 390 times. 32/390 can be reduced to 16/195, which I believe is in it's simplest form (no number can go into both 16 or 195 evenly). </span>
<span>All the other ratios are solved similarly, so I think you can do it. </span>
<span>XD hopefully I explained it correctly, but you should also ask an adult to help you and/or correct your homework when you're done.</span>
Answer:
Step-by-step explanation:
11) y = -1x - 2
12) y = -(3/2)x + 3
13) y = 3x - 2
14) y = (3/4)x + 1
15) y = (1/2)x + 1
16) y = -(2/5)x
17) y = 7x + 2
18) y = (4/3)x - 4

The correct answer is B. Hope this helps!
Has to be the first one because Yk how they do it so yea
Answer:
$466
Step-by-step explanation:
Represent her salary by s. Then the amount spent on rent is s/2.
After spending 168 on her electric and water bills, she had s/2 - 168 dollars left. She spent half of this on her phone bill, leaving her with
s/2 - 168
-------------- dollars.
2
After buying $57 worth of gas, she had
s/2 - 168
-------------- - 57 dollars left, and this came to $92.
2
We must now solve for s.
First, multiply all three terms by 2. We get
s/2 - 168 - 2(57) = 2(92), or
s/2 - 168 - 114 = 184
Simplifying this, we get s/2 = 168 + 114 + 184, or s/2 = 466.
She spent half her salary (that is, half of s) on rent. As seen above, this is $466.
