Answer: -25 / 36
Solution:
Step 1: Lets flip the division sign to multiplication
Note : when the sign is reversed, the second term in the equation will have the numerator and denominator swapped
-5/8 ÷9/10 > > > > > > -5/8 * 10/9
Step 2 : so it will be
-5/4 * 5/9 when simplified, which would be -25 / 36 > > > > > - 0.69
Hope this solution will help you understand the problem and don't forget the negative sign it may cost you marks :)
Heath needs to end up with 10L of solution,
of which 9L is bleach. So let m = liters of 20%
solution needed. Then .20m liters of that are bleach.
He must then add p liters of bleach to make
a total of 10 L. That is, p + m = 10. So the system is
m + p = 10, .20m + p = 9. Solving,
<span>m = 1.25 L 20% solution, and thus p = 8.75 L bleach.</span>
The system r+l = 46 and 15r + 9l = 396 can be used to determine the number of raspberries boxes and lemon seed boxes sold.
Step-by-step explanation:
Given,
Cost per box of raspberry = $15
Cost per box of lemon seeds = $9
Total boxes sold = 46
Total revenue generated = $396
Let,
r represent the number of raspberries sold
l represent the number of lemon seeds sold
According to given statement;
r+l = 46 Eqn 1
15r + 9l = 396 Eqn 2
The system r+l = 46 and 15r + 9l = 396 can be used to determine the number of raspberries boxes and lemon seed boxes sold.
