This student is incorrect because there is no number that you can multiply by 2 to get 5. Therefore, the proper point would be (1, 5) as the equation is setup as x+2y=5, so x must equal 1, and y must equal 2. Now to check if its correct:
1+2(2)=5
2x2=4
1+4=5
It is correct, so the answer is (1, 5)
Answer:
437+36x≥500
Step-by-step explanation:
At x miles per day, Santiago will walk 36x miles in 36 days. He wants the total of that distance and the 437 miles he's already walked to be at least 500:
36x +437 ≥ 500 . . . . . . . matches the 3rd choice
The best answer is C : The sum of the measures of two angles os 180 degrees .
We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.
Side PQ =
Side QR =
Side RP =
So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7
You probably misplaced the digits in option A. The correct answer is 19.7 units.
