The cost of each plane ticket for the baltaza family’s summer vacation is $329. if there are 7 family members, what is the total cost of the plane tickets ?

The total cost of plane tickets is $2303

Step-by-step explanation:

Given :

The cost of each plane ticket  is $329.

There are 7 members in a family going on summer vacation by plane

To Calculate : Total cost of the plane tickets.

Solution :

Since we are given that the cost of 1 ticket is $329.

And there are seven members in a family who are going by plane

So, Cost of 7 plane ticket's = 329*7 = $2303

Hence The total cost of plane tickets is $2303.

(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

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
