7 x 7 = 49. 49/2 = 24.5
The area is 24.5 units squared.
Answer:
Step-by-step explanation:
I take it that this is some sort of ratio. Start by solving the brackets on the left.
Brackets: 1/3 - 1/10
Brackets: 10/30 - 3/30
Brackets: 7/30
Brackets^2: 49/900
Brackets^2 - 1/5: 49/900 - 180/900
Brackets^2 - 1/5: -131/900
(2/5)^2 = 4/25
The way this read, it should be
Which when you invert and multiply becomes
which finally becomes
Answer:
14 I believe
Step-by-step explanation:
Well, 5/30 is 1/6 and 1/6 of 84 is 14 because 14 x 6= 84.
The solution of the expression is n = 3 and all the correct statement are shown below.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is;
⇒ - 7n + 11 = - 10
Now,
Solve the expression as;
Steps Reasons
⇒ - 7n + 11 = - 10 Given
⇒ - 7n + 11 - 11 = - 10 - 11 The property of equality was applied
⇒ - 7n = - 21 Addition and subtraction of numbers
⇒ - 7n / -7 = - 21/-7 The property of equality was applied
⇒ n = 3
Thus, The solution of the expression is n = 3 and all the correct statement are shown above.
