2 answers:

6 0

Get x all by itself and everything else on the opposite side of x.

-12 = 8 - 4x
-20 = -4x <-- Subtract 8 from each side
5 = x <-- Divide both sides by -4

So, x is equal to 5.

-12= 8-4x
-8 -8
-20=-4x
/-4 /-4
5=x

a man walked for some distance at 8 km /h and for an equal distance at 5km/h. the total time he took was 3 whole number 1/4 hour

slega [8]

Answer:

the total distance walked is 20 km

Step-by-step explanation:

The computation of the total distance he walked is shown below:

Let us assume the total distance walked be d

Now the total time would be

Total time = (d ÷ 2) ÷ 8 + (d ÷ 2) ÷ 5 = 3.25

d ÷ 16 + d ÷ 10 = 3.25

(5d + 8d) ÷ 80=3.25

13d = 260

d = 20 km

Hence, the total distance walked is 20 km
