Write and simplify an expression for the total cost of six friends

to go to the museum if only four friends view the mummy

exhibit.

ons

6x + 4

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.

We need to find the total cost

Given that:

The cost to  the museum and visit the mummy : 3(x+1)

Cost for 4 friend without seeing the mummy: x

=> The total cost:  3(x+1) + x = 3x+ 3+x = 4x + 3

Six friend pay x for admission and four friends pay 1 for the exhibition

The cost to  the museum for 2 people who dont watch the exhibition: 2x

The cost to see the mummy exhibition for four friends is: 4* (x+1)

=> the total cost: 2x+ 4* (x+1)  = 2x + 4x+4 = 6x + 4

17 1/3

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
