At start Keenan has x strawberries. He gives Tisha x/2. Then Tisha keeps 4 strawberries and gives Suvi the rest. If y is the number of strawberries that Suvi gets:
y = x/2 - 4.
For example: Keenan has 20 strawberries. He gives Tisha 10 and Tisha gives Suvi 6:
6 = 20/2 - 4
6 = 10 - 4

Answer:
What is the concentration of H+ ions at a pH = 2?
⇒ 0.01 mol/L
What is the concentration of H+ ions at a pH = 6?
⇒ 0.000001 mol/L
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
⇒ 10,000

Explanation:
The square base of the pyramid has four sides with length 15 inches, making its perimeter four times that, or 60 inches. The slant height is
112×60=90 inches.
Therefore, the area of the base is B=152=225 square inches.
Each of the four lateral triangles has area 12⋅15⋅90=675 square inches.
The total surface area is 225+4⋅675=2,925 square inches.
