Answer:

the third side is 5 2/3 in.

s - 1

Step-by-step explanation:

a = side 1

b = side 2

c = side 3

a + b + c = 15

a = b - 4 => b = a + 4

c = a + 3

a + a + 4 + a + 3 = 15

3a + 7 = 15

3a = 8

a = 8/3 = 2 2/3 in

b = a + 4 = 6 2/3 in

c = a + 3 = 5 2/3 in

How do you solve an inequality that has a fraction (with a variable as the nemurator/demoninator
vichka [17]

Answer:

Solving with an equality is just simply the same as solving any algebra equations. If you were given a fraction, then just multiply both sides.

Example:

4 + \frac{x}{2} > 14

Subtract 4 on both sides:

4 - 4 + \frac{x}{2} > 14 - 4

\frac{x}{2} > 10

Now <em>multiply both sides by 2</em>:

\frac{x}{2} × 2 > 10 × 2

x > 20
