Mathematics
1 answer:
Svetradugi [14.3K]4 years ago
3 0

Answer:

536.6

Step-by-step explanation:

First I found the area for the rectangles which is (15x10) multiplied by 3.

Then I found the area for the triangles which is A=(1/2)(8.66)(10). Which equals 43.3, then multiplied that by 2.

Add all the areas together (150)(3)+(43.3)(2)=536.6

X + 2y = 200<br> x = y + 50
Simora [160]

Answer:

x = 100

y = 50

Step-by-step explanation:

if x = y + 50,

putting the value of x in first equation we get,

  • x + 2y = 200
  • y + 50 + 2y = 200
  • 3y = 200 - 50
  • y = 150 / 3
  • y = 50

putting the value of y in second equation,

  • x = y + 50
  • x = 50 + 50
  • x = 100
