5 * 3 does not tell you the total number of flash cards in 5 piles because you don't know how many cards are in each pile.
Mark me Brainliest pls!!!! It will help me rank up!
Hello there,
First you need to add together the numbers.
4+5+9 = 18
Divide the total by this,
180 / 18 = 10
Multiply each number by 10.
40:50:90.
Hope This Helps You!
Good Luck Studying :)
X= a number
If 52 is 130% of a number, then we multiply the unknown number by 130%.
x * 130%= 52
convert % to decimal (130%÷100)
1.3x= 52
divide both sides by 1.3
x= 40
ANSWER: The unknown number is 40, so it is less than 52. We multiply the unknown number by 130% to equal 52.
Hope this helps! :)
5(5r-7)=-185
25r - 35 = - 185
25r = - 150
r = - 6
45.34 X 3= 136.02
212.52 - 136.02= 76.50
76.50/3= 25.50
the answer is $25.50
