**Answer:**

162.5

**Step-by-step explanation:**

65 time 2

then divide 65 by two as your half

then 32.5 plus 130

which is 162.5 miles

The solution can be obtained as follows:

We are given the speed of the ship as 20 km/h

Time taken by ship to travel is 4h.

We will apply speed distance formula here given by:

So here we will plug in the given values to find the distance covered by the ship:

Distance = 80 km

**Answer: The distance traveled by the ship is 80 km.**

Remember that you can do anything ot an equaiton as long as you do it to both sides

-8+x=0

add 8 to both sides

8-8+x=0+8

0+x=8

x=8

answer is B. 8

**Answer: 36 and 28**

**Step-by-step explanation:**

x + x+2 = 74

2x = 72

x1 = 36

x2 = 28

Answer:

Step-by-step explanation:

The proportion that Alan solved was

x/200 = 8/25

His working as shown was

(8)(x) = (25) (200)

8x = 5000

He divided both sides of the equation by 8. It became

8x/8 = 5000/8

x = 625

The correct steps are

25x = 200 × 8 = 1600

Dividing both sides of the equation by 25, it becomes

x = 1600/25

x = 64

Alan's error were:

1) He got the wrong product when he multiplied 25 by 200.

2)He got the wrong quotient when he divided 5,000 by 8.
