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

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
