Due in 20 minutes ! : ( the attendance of your club increased by 30% from last year. there are 195 people in the club now. how many people were in the club last year? ( provide steps )

150 people were in the club last year

Step-by-step explanation:

suppose,

Last year there were x people in the club last year

now,

The attendance of the club increased by 30%  from last year

∴At present the amount of people are in the club =x+(x . 30%)

                                                                                    =x+(x . 30/100)

                                                                                    =x+(30x/100)

                                                                                    = (100x+30x)/100

                                                                                    =130x/100

Given that,

There are 195 people in the club now

∴130x/100=195

=>130x=19500          [multiply both sides by 100]

=>x=19500 /130       [divide both sides by 130]

=>x=150

∴150 people were in the club last year

150

Step-by-step explanation:

There are 195 ppl in the club this year so all i did was add 30% to145-150 until i got the answer witch is 150

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
