Olegator [25]

Answer:

Sydney is 44 years old

Step-by-step explanation:

Step 1: Make a system of equations

d = s - 15

d + s = 73

Step 2: Plug in s - 15 for d in the second equation and solve

s - 15 + s = 73

2s - 15 = 73 + 15

2s / 2= 88 / 2

s = 44

A window shaped like a parallelogram has an area of 23 4/5 square feet. The height of the window is 2 4/5 feet. How long is the

USPshnik [31]

Answer:

base = 8 $\frac{1}{2}ft$

Step-by-step explanation:

The general formula for the area of a parallelogram is:

A = bh, where b = the length of the base and h = the height

Using the given values for area and height, we can solve for the missing variable of 'b':

23 $\frac{4}{5}=\frac{119}{5}$

2 $\frac{4}{5}=\frac{14}{5}$

$\frac{119}{5}=\frac{14}{5}h$

Multiply both sides by the reciprocal:

$(\frac{5}{14})(\frac{119}{5})=(\frac{14}{5})(\frac{5}{14})h$

$\frac{119}{14}=h$

$h=8\frac{1}{2}ft$
