Answer:
8 laps in 70 seconds is faster.
Step-by-step explanation:
If we divide 70/8 and 98/12 we get the following:
70/8= 8.75
98/12=8.16
8.75>8.16
The unit rate is 1 lap in 8.75 seconds and 1 lap in 8.16 seconds
Answer:
Step-by-step explanation:
j=k+4
k=3r
j=3r+4
j+k+r=46
3r+4+3r+r=46
7r+4=46
7r=42
r=6, since k=3r
k=18, since j=k+4
j=22
j,k,r=22,18,6
600+30+7 if that is what you meant...
0.275
275 is in the thousandths place, therefore the numerator will be 275 and the denominator will be 1000.
275/1000 is our new fraction, but we must simplify. 5 goes into both numbers, so 275 divided by 5 is 55 and 1000 divided by 5 is 200. 55/200 is our new fraction. We keep dividing by 5 until you can't anymore.
So when that's done the simplified fraction is 11/40.
