Answers

If you would like to increase £84 by 3%, you can calculate this using the following steps:

3% * £84 = 3/100 * 84 = £2.52

£84 + £2.52 = £86.52

The correct result is £86.52.

Simplify radical. Intermediate Algebra

Answers

180 ÷ 2 = 90; 90 ÷ 2 = 45 ; 45 ÷ 3 = 15 ; 15 ÷ 3 = 5 ; 5 ÷ 5 = 1 => 180 = (2^2) * (3^2) * 5 => √(180) = 2*3 * √(5 )=6 √(5) ;

In the same way we have √(245)=7 √(5) ; and √(320 )=8 √(5) ;

Finally, 6 √(5)+7 √(5) - 8 √(5) = 13 √(5) - 8 √(5) =7 √(5).

2.25x -20 = 6.5x +14

Answers

Answer:

Step-by-step explanation:

6.5x + 14 = 2.25x - 20

4.25x + 14 = -20

4.25x = -34

x= -8

Answer: -8

Step-by-step explanation: 2.25x-20 = 6.5x +14

Subtract 14 on both sides and rearrange, 6.5x= 2.25x -34

then subtract 2.25x from both sides, 4.25x= -34

Finally divide both sides by 4.25 to get x = -8
