Answer:
D. 140
Step-by-step explanation:
(D) 140 coins
Kate kept seven coins in the box, which is 5% of the entire collection.
This means that 5% of the coins = 7 coins
To find the total number of coins in the box, we need to find 100% of the coins.
5% = 7 coins
To get to 100%, we multiply the equation by 20 (because 5 x 20 is equal to 100).
100% = 7 x 20 = 140 coins
52488y²
first solve for 3³. then solve for 18²
3³=27
18²=324
27*324=8748
then multiply 8748 by 6y²
=52488y^2
this is your answer. thanks!!
