Giving 50 points and brainliest for who ever can show the work to me understand the it would be highly appreciated < 3

So we have ratio 5/7, and sum is 168, so clearly numbers are not 5 and 7 since 5 + 7 = 12, not 168, so ratio is 5x / 7x, where x is unknown number.

So now we can set up sum: 5x + 7x = 168

12x = 168

x = 168 / 12 = 14

So our two numbers are 5x and 7x, which are 5 * 14 = 70 and 7 * 14 = 98

So the answer is 70 and 98

Well you can start by figuring out what numbers add up to get 168
and you know that half of 168 would be 84.
 so that would mean that the two numbers are

and we know that there are 12 parts soo you can multiply 168 by 12 and you would get 14 for each part
then you multiply 14 by 7 and by 5

so the ratio would be 70 as 5::98 as 7

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
