Answer:
$1.94
Step-by-step explanation:
Cost of 3 folders = $2.91
We need to find the cost of 2 folders.
First we will find the cost of 1 folder
1 folder = $2.91/3 = $0.97
To find the cost of 2 folders, multiply $0.97 and 2
2 folders = $0.97 × 2
= $1.94
Hence, the cost of 2 olders is $1.94.
92°
By exterior angle theorem:
(180-30)/2 would be the equation and the answer is 150/2
the answer is 40:15
Hint : They are a all common factors of 5
You divide each of them by 5 then add them all together then you will get your answer.
Good luck!
