Answer:
73 mph during the second hour!
Step-by-step explanation:
Hour 1=54 mph
Hour 2=? mph
Hour 3=82 mph
Total=209 mph
this means that 209=82+54+?
Simplify it and you will get 73
73 mph
Another way to put 6/7 - 1/8 is 48/56- 7/56 since the LCM of 7 and 8 is 56 (if you don’t know what that is I can explain it) sorta like subtraction you subtract both numerators (48 and 7 or 48-7) which gives you 41 then you put the denominator (56) below that. So in other words it equals 41/56
Simplify 140/96 into 35/24 since they have the common factor 4. Then convert it to 1 whole and 11/24
<em><u>Answer:</u></em>
(7, -5)
<em><u>Step-by-step explanation:</u></em>
We can see the dot, is 7 units to the right of the y axis, and 5 down from the x-axis. We then can create the coordinates because we know where it is:
If it is on the right side of the y-axis, it is positive. If it is below the x-axis, it is negative so:
(7, -5) would be the coordinate point
