Step-by-step explanation:
5/9m=15
9/5x5/9 cross that out and you have to do 15/1x9/5 which is 3/1x9/1 which is 27 muffins.
multiple 9/5 by 5/9 because of the recipricol which evens out that number because it becomes whole. then do the same thing to the 15 and you simplify both the fractions then multiply which creates 27, or just look at 5/9 and 15/x 15 divided by 5 is 3 and 3 times 9 is 27 tada!!
Answer:
c) 2(2y+1)
Step-by-step explanation:
This is because when the tables are together there can be 4 people at each table, plus 1 at either end. Whatever equation you have must have +2 in it, to account for the ends of the tables. The number of tables (y) must be multiplied by 4 because there are always 4 people per table. The number of tables is unknown so 4y must be in your equation.
2(2y+1) simplifies to 4y+2, which is the equation we want.
We can start by separating the x^3, and that means we have to multiply both sides by 4, resulting in x^3=27. Next, we can find the cube root of both sides ( as x is the cube root of x^3), getting x=3
$15.81
15% of $20 is $3 so subtract that from $20 and u get $17.
Then 7% of $17 is $1.19 so subtract that from $17 and you get $15.81, which is the amount Lin’s father would pay for the meal in the end.
