Answer:
5
Step-by-step explanation:
7.25y = 36.25. (after adding 15 on both sides)
Then divide by 7.25 and it should come out to 5. Hope this helps! :D
Answer:
Length = 24 and Width = 81
Step-by-step explanation:
Let Width be W
then Length = W-57
Perimeter of rectangle = 2(Length + Width)
=2 (W-57+W)= 210
4W- 114= 210
4W= 324
W= 81
Then Length = 81-57 = 24
Answer:
approximately 2,800
Step-by-step explanation:
you would round 691 to 700 then multiply by 4
Answer:
![d_R_T=10\ units](https://tex.z-dn.net/?f=d_R_T%3D10%5C%20units)
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
![d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28y2-y1%29%5E%7B2%7D%2B%28x2-x1%29%5E%7B2%7D%7D)
we have the coordinates
R(−7, 3) and T(3, 3)
substitute in the formula
![d=\sqrt{(3-3)^{2}+(3+7)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%283-3%29%5E%7B2%7D%2B%283%2B7%29%5E%7B2%7D%7D)
![d=\sqrt{(0)^{2}+(10)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%280%29%5E%7B2%7D%2B%2810%29%5E%7B2%7D%7D)
