Answer:
x = -1/5y + 3/5
Step-by-step explanation:
y = 3 - 5x
Subtract 3 from both sides;
y - 3 = -5x
Divide both sides by -5
-1/5y + 3/5 = x
-3+-6=-9 -9 is how many yards the football team has lost overall in the two plays
Here’s what you can do to make this very simple. Consider that the “missing” space between the rectangles isn’t there. Then, find the area:
10 x 9 = 90 mm
Now, find the area of the “missing” part.
5 x 2 = 10 mm
Finally, you deduct the missing part from the complete rectangle!
90 - 10 = 80 mm
The area of this whole thing is 80 mm!
