(7x-10) - (-6x-8)
distribute the negative to the (-6x-8)
(7x-10) + 6x+8
disregard the parenthesis because addition is associative
7x-10 + 6x+8
combine like terms
13x-2
13x-2 is the answer
Answer:
63.59 in²
Step-by-step explanation:
The formula to find the area of a square: a², where a is the side.
The formula to find the area of a circle: πr², where r is the radius (diameter ÷ 2), and the pi is alterable (3.14 or 3.142 or 22/7).
1) Find the diameter of the circle. The side of a square is the diameter.
a²
a = √81
a = 9
2) Plug the values into the formula of the area of a circle. 9 ÷ 2 = 4.5 (radius).
= 3.14 x 4.5²
= 3.14 x 20.25
= 63.585
3) Round off the result to the nearest hundredth.
= 63.59
The solution to given inequality is:
x<3
Step-by-step explanation:
We have to solve the given inequality to get the value of x
Given inequality is:
Adding 20 on both sides
Dividing both sides by 5
The solution to given inequality is:
x<3
x will be equal to all values less than 3
