Answer:

The graph in the attached figure

Step-by-step explanation:

we have

3x < -9

solve for x

Divide by 3 both sides

3x/3 < -9/3

x < -3

The solution is the interval------>(-infinite, -3) -

All real numbers less than -3

In a number line the solution is the shaded area to the left of the dashed line (open circle)

see the attached figure

Kruka [31]

Answer:

Lola was in lead for \frac{6}{25} of a mile.

Step-by-step explanation:

We have been given that Lola and Brandon had a running race. They ran 3/10 of a mile. Lola was in the lead for 4/5 of the distance.

To find the fraction of a mile for which Lola was in the lead, we need to find 4/5 of 3/10 as:

\text{Fraction for which Lola was in lead}=\frac{3}{10}\times\frac{4}{5}

\text{Fraction for which Lola was in lead}=\frac{3}{5}\times\frac{2}{5}

\text{Fraction for which Lola was in lead}=\frac{3\times2}{5\times5}

\text{Fraction for which Lola was in lead}=\frac{6}{25}

Therefore, Lola was in lead for \frac{6}{25} of a mile.

What is 4/3 subtracted by 2/5
yKpoI14uk [10]

In order to subtract fractions, we must find a common denominator, then subtract the numerators.

The common denominator (LCM(3, 5)) is 15.

We must multiply the first numerator by 5, because 3*5=15 and the second numerator by 3 because 5*3=15.

We get \frac{20}{15} - \frac{6}{15}.

All we need to do now is subtract the numerators: \frac{14}{15}.

The answer is 14/15.
