I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250
250+120=370!!
answer : 370 kilometers per hour
22-7-7-7=1 this will show that you can subtract 7 three times from 22 and have a remainder of 1.
3(5+7) is the problem you are looking at. To figure it out, you can use properties. On the right side of the equals sign, it shows a property you can use to do the problem. In this case, they are distributing.
i believe (x,y) will turn into (y,-x), so your answer is (5,-2)
Yes as long as you keep the sign in front of it
