Answer:

Step-by-step explanation:

There are 2 similar triangles.

EDA and CBA

From that we can get the following proportion.

ED / CB = AD / AB

Filling in the letters we get

6/x = (4 + 3)/3 Combine

6/x = 7/3 Cross Multiply

7x =6*3

7x = 18 Divide by 7

x = 2.57

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

What does this equal too

GREYUIT [131]

10/24.

If you find the LCM of the denominators, you change the denominators to that, then take the LCM / denominator and multiply the numerator by that, making 18/24 and - 8/24. subtract with the numerators: 18 - 8 = 10. the result is 10/24
