Answer:
y = x/(x - 1) .
Step-by-step explanation:
1/x + 1/y = 1
Multiply through by xy:
y + x = xy
xy - y = x
y(x - 1) = x
y = x/(x - 1) answer.
2 1/2 yds = 2.5 x 36 = 90 inches...what she started with
2 ft 8 in = 2(12) + 8 = 32 inches...what she had left
90 - x = 32
90 - 32 = x
x = 58 inches....so she used 58 inches
Answer:
yes
Step-by-step explanation:
f the exterior angle of a polygon is given, then the formula to find the interior angle is Interior Angle of a polygon = 180° – Exterior angle of a polygon Method 3: If we know the sum of all the interior angles of a regular polygon, we can obtain the interior angle by dividing the sum by the number of sides
the common difference is -7
