Which ratio is different? 3 : 7 3 to 7 3/7 7 to 3

Mathematics
1 answer:
Masteriza [31]3 years ago

Answer:

7 to 3 is this answer

Step-by-step explanation:

if you noticed, with all the other ones they all have 3 : 7 in it. So by the process of elimination it's 7 to 3 that is different. I'll tell you why,

3 : 7, that is the ratio we have as an example. That's why it isn't the different one.

3 to 7, you say 3 : 7 as 3 to 7 to it still has the same ratio

3/7, this is how to type the fraction version of the ratio so it makes sense that it is the same one as 3 : 7.

7 to 3, if you haven't noticed yet, all of them has 3 : 7 as a counterpart. They are all the same but this one, this is 7 : 3 or 7 to 3. So with logic, this is the different ratio.

joe is in debt $250, but he's saving $30 each month. using the equation, y=30x-250, how long will it take joe to have $230?
Vsevolod [243]

Answer:

16

Step-by-step explanation:

so in this equation we have 2 variables, and we must figure out what those variables mean:

y: "y" is the total amount of money joe has after subtracting his debt from it

x: "x" is the # of months as the cost of each month(30) is placed just before this variable

as y is the total amount of money joe has we need to substitute it for 230 to figure out how long it took for joe to recieve that much money

230=30x-250

480=30x

x=16

it took joe 16 months to get $230
