Answer:
10 x -6y = -76
-56 - 10x - y = -76
10x - 6y = -76 (-56) - (-76) = 20
-10 x -y = -20
10x - 6y = -76
-10x -y =-20
10x cancels
76 + 20 = 96
-7y = - 96
divide both sides by -7
y = 96/7
substitute into -10x - y = - 20
- 10x - 96/7 = - 20
96/7 is a fraction btw
= -10 x = - 20 + 96/7
-20 + 96/7
-10 x = -44/7
divide by - 10
x = 22/ 35 ( a fraction)
(x,y) = (22/ 35) ( 96/7)
Answer:
the area of the glass is 1000cm^2
Step-by-step explanation:
Given that
The side is 50 cm
And, the power is 40 cm
We need to find out the area of the glass
So, the area of the glass is
= (50 × 40 ) ÷ 2
= 2,000 ÷ 2
= 1,000 cm^2
Hence, the area of the glass is 1000cm^2
