We know that the opposite is the additive inverse.
For example, 8+(−8)=0 where 0 is the identity for addition.
Given that we have to compute the sum of 5x+20 and the opposite.
Given
5x+20
opposite of 5x+20 = -(5x+20)
so
The sum of 5x+20 and the opposite:
5x+20 + -(5x+20)
Distribute the Negative Sign

Therefore, the sum of 5x+20 and the opposite is: 0
Thus, the equivalent expression is:
Answer:
Option (E)
Step-by-step explanation:
In the figure attached,
Given a isosceles right triangle with two equal legs measuring 
units
By Pythagoras theorem,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
Since, hypotenuse = h
Leg 1 = Leg 2 = 3√2
Now we substitute the values,
h² = (3√2)² + (3√2)²
h² = 18 + 18
h = √36
h = 6 units
Therefore, length of the hypotenuse is 6 units.
Option (E) will be the answer.
Answer: 10
Step-by-step explanation:
2.5 times 4
Mrs Hamilton's commision
175000 x 0.04 (4%) = 7000
Mrs Hamilton received 4725
7000 x 0.01 = 70 (1%)
4725 / 70 = 67.5%
She received 67.5% of her total commission
David's Computer = C
Working
1080 x 0.8 (80%) =864
864 x 1.08 (108%) = 933.12
The computer cost $933.12 dollars
Suzanne's sweater = B
$40 / 100 = 0.4 (1%)
40 - 25 = 15 (difference)
15 / 0.4 = 37.5%
Suzanne received a discount of 37.5%
