Answer:

a = 55

Step-by-step explanation:

1. Set up the equation: 0.2a = 11 (20% is equal to 0.2 because to convert a percentage to a decimal you divide it by 100. In math, "of" means "times" and "is" means "equals" so the equation is 0.2 x a = 11, which can be shortened to 0.2a = 11).

2. Divide both sides by 0.2. You will be left with a = 55.

A line has a slope of 5 and passes through the point (-1,2).
Andreyy89

Answer:

Step-by-step explanation:

slope=m= 5

points=(-1,2)

<u>By point-slope form:</u>

y-y_{1}=m(x-x_{1})

<u>Substitute the values in formula:</u>

<u>y-2=5(x+1)</u>        (It is the point slope form)

Now,

<u>Slope intercept form:</u>

y-2=5x+5

y=5x+5+2

<u>y=5x+7</u>

The Knicks and Nets have a total 30 players.
Blababa [14]

Answer:

Step-by-step explanation:

From the problem statement, we can set up the following two equations:

K + N = 30

20K + 10N = 500

where K is the number of Knicks players, and N is the number of Nets players.

We can substitute the first equation into the second and solve for K

K + N = 30

N = 30 - K

20K + 10N = 500

20K + 10(30 - K) = 500

20K + 300 - 10K = 500

10K + 300 = 500

10K = 200

K = 20
