Two families visited an amusement park. The first family bought 2 hot dogs and 3 bottles of waters, which totaled $18. The secon

Ghella [55]

Answer:

$6.00

Step-by-step explanation:

To solve this problem, we have to construct two separate equations for each family, and then use any of the methods for solving simultaneous equations.

Let's consider h to represent the cost of 1 hot dog, and w to mean the cost of 1 water bottle.

• For the first family:

$2h + 3w = 18$

We can rearrange the equation to make w the subject:

⇒ $3w = 18 - 2h$

⇒ $w = \frac{18 - 2h}{3}$

• For the second family:

$4h + 2w = 28$

Since we have previously obtained an expression for w in terms of h, we can substitute that expression for w in the above equation, and then solve for h:

⇒ $4h + 2(\frac{18 - 2h}{3}) = 28$

⇒ $4h + \frac{36 - 4h}{3} = 28$

⇒ $12h + 36 - 4h = 84$ [Multiplying both sides of the equation by 3]

⇒ $8h + 36 = 84$

⇒ $8h = 48$

⇒ $h = \bf 6$

∴ The price of one hot dog is $6.00.

Consider the graph of Bx + Cy = A where A, B, and C are all positive constants. Find the coordinates of the x-intercept. Use upp

timofeeve [1]

That is where the line crosses the x axis or where y=0
set y=0
Bx=A
find x value
divie both sides by B
x=A/B
the x intercept is x=A/B

7 times as much as the sum of 1/3 and 4/5

musickatia [10]

1/3+4/5= 17/15
The commun multipleof 3 and 5 is 15.
1/3×5= 5/15
4/5×3= 12/15
5/12+12/15= 17/12

17/12×7= 119/84

119/84

Hope this helps! :)
