If Lea has given 23 surveys and has to give twice that then 2*23 = 46 which is the total amount needed. Therefore if she has already done 23 out of those 46, then 46-23 is the amount she still has to do. 46-23=23... Lea needs to do 23 more
Answer:
Step-by-step explanation:
Given
Shape: Parallelogram
∞
Required
Determine the height
Area of parallelogram is calculated as:
Substitute values for Area and Base
Make Height the subject
<em>Hence, the height of the parallelogram is 2cm</em>
Cleary it fits 1 2/3 3/5 more than twice
Commutative property: when you have to solve a sum, it does not matter the order in which you place your addends, since you will always get the same result.
We have then:
((40) + (185)) + (240) = 465
(240) + ((40) + (185)) = 465
answer:
Form 1:
((40) + (185)) + (240) = 465
Form 2:
(240) + ((40) + (185)) = 465
