Answer:
126 minutes or 2 hours and 6 minutes
Step-by-step explanation:
Find how long it took her to swim one lap
1 hour and 30 minutes = 90 minutes
90/5 = 18
This means it took her 18 mins to swim each lap
18 · 7 = 126
It took her 126 minutes/2 hours and 6 minutes to swim 7 laps
Answer:
x=45/6
Step-by-step explanation:
2+7y=8. 7y=8-2. <u>7</u><u>y</u><u>=</u><u>6</u>
7=7. y=6\7
insert the value of y in the second equation. 5x-7y=16
5x-7(6/7)=16
5x-49\6=16
collect the liketerms together
5x=16+49/6
5x=145/6(divide both sides by 5)
x=29/6
x=45/6
<em><u>f</u></em><em><u>u</u></em><em><u>r</u></em><em><u>t</u></em><em><u>h</u></em><em><u>e</u></em><em><u>r</u></em><em><u>.</u></em>
<em><u> </u></em>confirm if the 2 in the second equation has an X coz the questions are normally set with both equations having both values x and y
When two fractions have the same numerators, the one with the smaller denominator is the greater fraction.

So Kelvin is right.
Answer:
f || m
Step-by-step explanation:
If f is parallel to k and k is parallel to m
then f must be parallel to m
