<span>Simplifying 2x + 18y = 36 Solving 2x + 18y = 36 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-18y' to each side of the equation. 2x + 18y + -18y = 36 + -18y Combine like terms: 18y + -18y = 0 2x + 0 = 36 + -18y 2x = 36 + -18y Divide each side by '2'. x = 18 + -9y Simplifying x = 18 + -9y</span>

John &amp; friends brought 4 bags of popcorn and 3 sodas at the movie for a total of 13.50. At the next movie John &amp; 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.

A=2(LW+LH+WH)

A=2((7/8)(1/3)+(7/8)(2/5)+(1/3)(2/5))

A=2(7/24+14/40+2/15)

A=14/24+28/40+4/15

A=7/14+7/10+4/15  210

A=(105+147+56)/210

A=308/210

A=(210+98)/210

A=1 98/210

A=1 7/15
