Graph x<2/9 on a number line

Arturiano [62]

Answer:

The line should begin on the right side 2 dashes (the small lines tht go throught the number line. There are 9 dashes between each whole number.)

Then the line should go left because it says x is less than 2/9. (which is right)

The line segment you should choose is the one with the open circle with an arrow going to the left.

A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A lacrosse goalie saved 6 o

Crazy boy [7]

Answer:

Additional saves = <u>34 lacrosse.</u>

Step-by-step explanation:

The additional saves = s

Then , the number of saves becomes = 6+s

and, the number of shots faced = 13+s

Save percentage in lacrosse is found by dividing the number of saves by the number of shots faced that is

$\text{ percentage\ in\ lacrosse} =\frac{\text the \ number\ of \ saves}{\text the \ number of shots faced }$

$\text{ percentage\ in\ lacrosse} =\frac{6+s}{13+s }$

Given , the percentage of lacrosse = 0.850

${0.850 } =\frac{6+s}{13+s }$

${0.850 \times}({13+s })=6+s$

$11.05+0.850s=6+s$

$11.05-6=s-0.850s$

$5.05=0.15s$

$s=33.66$

Since, additional saves must be an integer so round it off to the nearest integer 34.

Thus, Additional saves = <u>34 lacrosse.</u>
