in a strawberry and banana smoothie the number of r bananas is one sixth the number of strawberries minus one. smoothie contains 2 bananas and s strawberries. How many strawberries are in Emma's smoothie
The equation would be r = 1/6*s - 1. Put 2=r, which would be 2 = 1/6*s - 1, add 1 to both sides, the equation would be 3 = 1/6*s, multiplying by 6 would make the equation 18 = 1*s, or s. Therefore, there are 18 strawberries.
