Answer: There is no solution.

Step-by-step explanation:

1.) 1 / 5 (25) + 1 / 5 (-5a) = 4 - a

2.) 5 - a = 4 - a

3.) 5 - a + a = 4 - a + a

4.) 5 = 4

The variable a is completely removed, leaving the final answer as 5 = 4, which isn't true.

Answer:

No solution

Step-by-step explanation:

  • 1/5(25 - 5a) = 4 - a

Start by distributing 1/5 inside the parentheses. 1/5 * 25 is 5 and 1/5 * 5 is 1. You have:

  • (5 - a) = 4 - a

Now you can remove the parentheses.

  • 5 - a = 4 - a

Subtract 4 from both sides of the equation.

  • 1 - a = -a

Add a to both sides of the equation.

  • 1 = 0

This is an incorrect or a FALSE statement, so this means that this equation has no solution.

Michele wanted to measure the height of her school’s flagpole. She placed a mirror on the ground 48 feet from the flagpole, then
yulyashka [42]
Height of the flagpole = x
distance from flagpole to the mirror = 48 ft
height of Michele = 5 ft
distance from Michele to the mirror = 12 ft

Now, set the proportion.

x/48 = 5/12
48 * x/48 = 5/12 * 48
x = 240/12
x = 20

So, the height of the flagpole is 20 ft.
