Estimate means to give a guess kinda. When you estimate lets say someone has 4 cookies and they also have $20 and the cookies are $6 a dozen. Take 20 divide it by 6 which would be 3.3333. That person can buy 3.3333 dozens. If you estimate that person can buy a total of 3 dozen. Hope this helped ;)
Since we're given y, we can substitute y into the first euqation...
-2x+3(3x+4)=19
-2x+9x+12=19
7x=7
x=1
hope this helps :D brainliest pls
Without a picture, it would be three linear pairs but to be more exact I would need a picture
hope this helps
14,378 + 16 = 14,394
14,394 - 422 = 13,972
There were 13,972 miles on the car at the end of the second year.
You have to add the amount of miles she drove the first year with the amount of miles that were already on the car when she bought it. Then you subtract 422 since that’s the decrease in miles for the second year. When you subtract, you should get that she drove 13,972 miles in the second year.
