Subtraction is finding the difference between two numbers whereas division is
putting numbers into equal pairs or undoing multiplication ( if that helps )
So...
If they say divide 6 by 2 they mean put six into equal pairs of 2 which would equal 3
E.g.:-
( there are 3 pairs of six cars in twos )
You can't use subtraction because that will just find the number difference of 6 and 2 which is 4
Hope that wasn't complicated
Jamal's Lawn Service will charge $28 for fertilizing this lawn.
Step-by-step explanation:
- Step 1: Find the area of the lawn. It is in U shape which is a rectangle from which a square has been cut off. So the area of the lawn can be found by subtracting the area of the square from the area of the rectangle.
Area of the rectangle = length × width; here length = 4 yd and width = 3 yd
⇒ Area = 4 × 3 = 12 yd²
Area of the square = (side length)²; Here side length = 2 yd
⇒ Area = 2² = 4 yd²
∴ Area of the lawn = 12 - 4 = 8 yd²
- Step 2: Find the cost of fertilizing the lawn.
Cost of fertilizing 1 sq. yd = $3.50
∴ Cost of fertilizing 8 sq. yards = 8 × 3.50 = $28
