Let rs.5 denominations be x , then rs 10 denominations will be 90-x
then total amount 5x + 10(90-x) which is rs.500
5x + 10(90-x) = 500
900 - 5x = 500
400 = 5x
therefore x = 80
therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
Answer:
40 cubes
Step-by-step explanation:
multiply side lengths or the prism by 2, then solve for volume
2.5 * 2 = 5
2 * 2 = 4
1 * 2 = 2
5 * 4 * 2 = 40
the answer is a actually C(n) =0.5n-3 ; $9.70 and an equation for 20 yogurts is 20(n)=c50-30 i did this once and my answer was similiar to this.
(x + 1)(2x^2 + 3x - 1) : Can be solved in multiple ways but easiest for me :P
x (2x^2 + 3x - 1) + 1(2x^2 + 3x - 1)
(2x^3 + 3x^2 - x) + (2x^2 + 3x - 1)
2x^3 + 5x^2 + 2x - 1
