Answer:
x=3, y=4
Step-by-step explanation:
To find the slide we can us the pythagorical theorem that say:
![h=\sqrt[]{l^2_1+l^2_2}](https://tex.z-dn.net/?f=h%3D%5Csqrt%5B%5D%7Bl%5E2_1%2Bl%5E2_2%7D)
Where l1 and l2 iare the leg of the triangle so in our problem will be:
![\begin{gathered} h=\sqrt[]{28^2+21^2} \\ h=\sqrt[]{784+441} \\ h=\sqrt[]{1225} \\ h=35 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20h%3D%5Csqrt%5B%5D%7B28%5E2%2B21%5E2%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B784%2B441%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B1225%7D%20%5C%5C%20h%3D35%20%5Cend%7Bgathered%7D)
So the slide is 35 ft
7+(10−4)2:4⋅231=7+62:4⋅81=7+36:4⋅81=7+9⋅81=7+89=7+181=881
Answer:
3 bottles
Step-by-step explanation:
1 bottle -- $1.20
x bottles -- 3.60 (total cost)
Therefore, number of bottles -- (3.60/1.20) = 3
She bought 3 bottles.
