Jina is running for president of the chess club, and she received 28 votes. There are 40 members in the club. What percentage of the club members voted for Jina?

70% of the members voted for Jina.

Step-by-step explanation:

votes : members

  28   :      40

  70   :      100

70% of the members voted for Jina.

70%

Step-by-step explanation:

To find the percentage, turn 28/40 into a fraction:

28

40

Then, keep simplifying it, or dividing it by the GCF.

28 14 7

> >

40 20 10

7/10 in a percentage is 70 percent since 7/10 can turn into 70/100

3.76%

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
