Answer:

So a bag of chip costs $2.39

Step-by-step explanation:

Let x = cost of a bag of chip

Let y = cost of a box of pretzel

Micheal buys two bags of chips and three boxes of pretzels for $5.13

This means

2x + 3y = 5.13 - - - - - - - - - -1

He then buys another bag of chips and 2 boxes of pretzels for $3.09

This means

x + 2y = 3.09 - - - - - - - - - - - -2

Solving equation 1 and equation 2 simultaneously and using the elimination method,

Multiply equation 1 by 1 and equation 2 by 2

2x + 3y = 5.13

2x + 6y = 6.18

Subtracting,

-3y = -1.05

y = -1.05/-3= $0.35

Put y= 0.35 in equation, x + 2y = 3.09

x + 2(0.35)= 3.09

x + 0.7= 3.09

x = 3.09-0.7 = $ 2.39

So a bag of chip costs $2.39

Given f(x) = 4x - 6 and g(x) = f(2x), write an equation for g.
AysviL [449]

f(x)=4x-6

g(x) = f(2x)

Substitute 2x into the first equation, which you get

f(2x)=8x-6

<h2><u><em>So, g(x)=8x-6</em></u></h2>

Two trains are traveling towards each other at a constant speed. The trains are currently 714 miles from each other. The speeds
shutvik [7]
55mph.

you can solve it using the equation distance=speed x time

your total distance is 714, and you have 2 trains, one traveling some speed, x, and one traveling x+8, both traveling for 7 hours. 
your equation would look like this
714 = x(7) + (x+8)(7)
and you can then solve for x, which would be 47. this is the speed of the slower train, but 47+8=55 with give you the speed of the faster train.

Before leaving to visit Mexico, Levant traded 270 American dollars and received 3,000 Mexican pesos. When he returned from Mexic
erica [24]

The amount of dollars that Mr. Levant would exchange for 100 pesos on his return is <u>$9</u>.

<h3>What is an exchange rate?</h3>

An exchange rate is a rate that is used to convert one nation's currency to another.

The exchange rate is based on the purchasing power of each nation's currency.

<h3>Data and Calculations:</h3>

Dollars before traveling to Mexico = $270

Value of Mexican pesos received for $270 = 3,000 pesos

Exchange rate = $1 = 11.11 pesos (3,000/$270)

Amount of pesos left after the trip = 100 pesos

Value of 100 pesos in dollars = <u>$9</u> (100/$11.11)

Thus, the amount of dollars that Mr. Levant would exchange for 100 pesos on his return is <u>$9</u>.
