This is called a double equation. If you solve for X, you would get 'any whole number.'
Answer:
Step-by-step explanation:
Let the speed of plane is p and speed of the wind is w.
<u>Then we have:</u>
- 10*(p + w) = 1120 ⇒ p + w = 112
- 20*(p - w) = 1120 ⇒ p - w = 56
<u>Sum the two equations and solve for p:</u>
- p + w + p - w = 112 + 56
- 2p = 168
- p = 84
<u>Find w:</u>
- 84 + w = 112
- w = 112 - 84
- w = 28
Step 1:
Start by setting it up with the divisor 5 on the left side and the dividend 33 on the right side like this:
5 ⟌ 3 3
Step 2:
The divisor (5) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:
0
5 ⟌ 3 3
Step 3:
Multiply the divisor by the result in the previous step (5 x 0 = 0) and write that answer below the dividend.
0
5 ⟌ 3 3
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.
0
5 ⟌ 3 3
- 0
3
Step 5:
Move down the 2nd digit of the dividend (3) like this:
0
5 ⟌ 3 3
- 0
3 3
Step 6:
The divisor (5) goes into the bottom number (33), 6 time(s). Therefore, put 6 on top:
0 6
5 ⟌ 3 3
- 0
3 3
Step 7:
Multiply the divisor by the result in the previous step (5 x 6 = 30) and write that answer at the bottom:
0 6
5 ⟌ 3 3
- 0
3 3
3 0
Step 8:
Subtract the result in the previous step from the number written above it. (33 - 30 = 3) and write the answer at the bottom.
0 6
5 ⟌ 3 3
- 0
3 3
- 3 0
3
Which equals 6
