Check the picture below.
now, we can solve x + 2y ⩽ 8, to what you see there in the picture, and as you already know, we start off by graphing the linear-version of it, namely x + 2y = 8 and the line of 3x = y, then after that we do the shading.
the lines are solid, because is ⩾⩽ and that includes the points along the line, for the shading we check the regions for "true" or "false" values, and the solution is where both shades meet, namely the "purple" area.
Answer
He got an 80
Step-by-step explanation:
50 - 10 = 40
40/50 as a whole number is 80
A plane is a closed two deminsional flat figure
Given :
A rectangular yard measuring 39 ft by 63 ft is bordered (and surrounded) by a 2 ft fence.
To Find :
The area of this walk.
Solution :
Area of whole park :
Now, length and breadth after removing the fences is l = 63 - 2( 2) = 59 ft and b = 39 - 2( 2 ) = 35 ft.
Area of inner park :
A' = 35 × 59 ft²
A' = 2065 ft²
Therefore, area of fencing is 2457 - 2065 = 392 ft² .
Hence, this is the required solution.
