the second one
Step-by-step explanation:
when you multiply 2 negative numbers they turn into a positive
15/-5=-3
Given:
3 teaspoons of salt for every 5 cups of flour.
How much salt is needed for 15 cups of flour?
This is a proportion problem:
a/b = c/d where ad = bc
3/5 = x/15
3*15 = 5x
45 = 5x
45/5 = x
9 = x
C. 9 teaspoons of salt is needed for 15 cups of flour.
3/5 = 9/15
3*15 = 5*9
45 = 45
Answer:
A. 2-liter bottle;$1.40
Step-by-step explanation:
We have to find out which option has the higher cost per liter. To do this we must find out how much each option would be if it was a liter.
1st set up each equation
2-liter = $2.80 we can divide by 2 on both sides of the equal sign and we get 1 liter = $1.40.
6(1/2) liter bottles = $3.90 this becomes 3 liters = $3.90 then we divide by 3 on both sides of the equal sign and we get $1.30
2nd we compare
$1.40(2 liter bottle) > $1.30 (6 1/2 liter bottles)
Ahh it’s the second option I believe!!
