Answer:

x = 27

Step-by-step explanation:

Use the ratio and proportion:

10 = 14

x + 8 2x - 5

just X multiply:

14 ( x + 8 ) = 10 ( 2x - 5 )

-6x = -162

x = -162 / -6

x = 27

10/14 = x+8/ 2x-5, so 10*2x-5= 14*x+8(cross multiplication)
So 20x-50= 14x+112(simplification), so subtract 14x: 6x-50=112, then add 50 to both sides: 6x=162, divide by 6: x=27

polet [3.4K]

Answer:

The cost of one canteen is $7.5

Step-by-step explanation:

We are given the following in the question:

Each brother purchase a new par of boots and two canteens.

Cost of one hiking boots = $34.00

Total cost of hiking boots =

$=34\times 2\\=\$68.00$

Let x dollars be the cost of one canteen.

Number of canteens bought by both brother = 4

Total bill = $98.00

Thus, we can write the equation:

$68 + 4x = 98$

Solving the equation, we get,

$68 + 4x = 98\\4x = 98-68\\4x = 30\\x = 7.5$

Thus, the cost of one canteen is $7.5
