1. Erwin hiked 5/7 of a kilometer while Jericho hiked 2/3 of a kilometer. How many
kilometers did they hiked in all?
Asked/ Problem: How many kilometers did
they hiked in all?​

the number of kilometers hiked in all is

Step-by-step explanation:

The computation of the number of kilometers hiked in all is shown below:

= Erwin + Jericho

Hence, the number of kilometers hiked in all is

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
