John & friends brought 4 bags of popcorn and 3 sodas at the movie for a total of 13.50. At the next movie John & friend
scoray [572]

Answer:

The cost of 5 bags of popcorn and 2 sodas is 14.25 units.

Step-by-step explanation:

We are given the following in the question:

Let x units be the cost of a popcorn bag and y units be cost of soda.

The cost of 4 bags of popcorn and 3 sodas is 13.50.

Thus, we can write the equation:

4x + 3y = 13.50

The cost of 2 bags of popcorn and 5 sodas is 12.00

Thus, we can write the equation:

2x+5y=12

Solving the two equations, we get,

4x + 3y-(4x+10y) = 13.5 - 24\\\Rightarrow -7y  =10.5\\\Rightarrow y = 1.5\\\Rightarrow 2x + 5(1.5) = 12\\\Rightarrow x = 2.25

Thus, the cost of popcorn bag is 2.25 units and the cost of a soda is 1.5 units.

Cost of  5 bags and 2 sodas

==5x+2y\\=5(2.25) + 2(1.5)\\=14.25

Thus, cost of 5 bags of popcorn and 2 sodas is 14.25 units.

Answer:

Psychology textbooks = 98 and physics textbooks = 294

Step-by-step explanation:

Let there are x psychology textbooks sold.

No of physics textbooks sold = 3x

ATQ,

A textbook store sold a combined total of 392 physics and psychology textbooks in a week.

x + 3x = 392

4x = 392

x = 98

It means there are 98 psychology textbooks sold and 3x = 3(98) = 294 physics textbooks sold.

I will give the BRAINIEST!!! Please help!!
kap26 [50]

Answer: B. y-1=2(x-3)

Step-by-step explanation:

First subtract both sides by 2x so it becomes -y=-2x-1

Second divide both sides by -1 so it becomes y=2x+1

After that to get it in the form they want it subtract 1 from both sides so that it becomes y-1=2x
