In my opinion I think that it would be 15cm
The area of a right triangle is 1/2*base height. The base is 6 and the height is 8, 6*8 = 48. After that, we multiple 48 by 1/2 which is 24. This is the are of the top and bottom triangles on #5.
2y + 2x = 6
2y - x = 12
Subtract
3x = -6, x = -2
2(-2) + 2y = 6
-4 + 2y = 6
2y = 10, y = 5
Final solution: x = -2, y = 5
Multiply 8 by 7.75 to get 62 then multiply by 3 to get 186 which is how much he gets paid per week
1.1% converts to 0.011 after moving the decimal point 2 spots to the left
Multiply this with 845.12
845.12*0.011 = 9.29632
Round 9.29632 to the nearest penny to get 9.30
Answer: B) $9.30
