5x3 + 5x2 - 19 is the answer
Answer:
28 minutes
Step-by-step explanation:
Speed = distance / time
Your speed is 1 lawn / 57 minutes. Your friend's speed is 1 lawn / 54 minutes. Working together, your combined speed is:
1/57 + 1/54
So the time it takes working together is:
Speed = distance / time
1/57 + 1/54 = 1 / t
t = 27.7 minutes
Rounded to the nearest whole number, it takes 28 minutes.

Answer: x=0 y=2
Step-by-step explanation:
Ratio of the sides of the triangles,
<em>2 : 3 : 4 </em>
Let's consider each side to be
2x,3x and 4x
Therefore the perimeter of the triangle is,
<em>2x + 3x + 4 x = 9x </em>
The shortest side is 15 inches.
We know that the smallest value in the above ratio is 2
Therefore,
2x = 15 inches
x = 7.5 inches
<u>☞</u><u>Perimeter of the triangle </u>
= 9x
= 9 * 7.5 inches
= <u>67.5 inches</u>
