Maggie = x years old
Demarco = x + 4
Anna = 3*Demarco
Anna = 3*(x + 4)
Anna = 3x + 12
Hope this helps!
Answer: The equation of the line in slope-intercept form is “y = 4/3x + 4.”
Area is length times width. Therefore, width is area divided by length. Convert 11 7/8 to the improper fraction 95/8 and convert 4 3/4 to 19/4. Then, you can fine 95/8 divided by 19/4 by flipping the second fraction and multiplying so that you have 95/8 times 4/19. 4 times 95 is 380 and 8 times 19 is 152. Therefore, the answer is 380/152. This is equivalent to 5/2 or 2.5.
