Ella swims four times a week at her clubs pool. She swims the same number of laps on Monday,Wednesday,Friday,and 15 laps on Satu

Reika [66]

She swims 12 laps on Monday.

Step-by-step explanation:

Total laps = 51 laps

Laps on Saturday = 15 laps

Let,

x be the number of laps on Monday, Wednesday and Friday each.

According to given statement;

Monday+Wednesday+Friday+Saturday = 51

$x+x+x+15=51\\3x=51-15\\3x=36$

Dividing both sides by 3

$\frac{3x}{3}=\frac{36}{3}\\x=12$

She swims 12 laps on Monday.

(-3,-10)

$\\ \rm\longmapsto 2(-3)-(-10)=4$

$\\ \rm\longmapsto -6+10=4$

Proved

If x<0 and y>0, determine the sign of the real number x-y/xy ...?

Ludmilka [50]

If x<0 and y>0, then the sign of the real number x-y/xy would be positive. <span>If x is negative and y is positive then x-y is negative and xy is negative. A negative number divided by another negative number would be positive. Hope this answers the question.</span>
