Let us say the number was x.
Mike added to it two other numbers.
First number added is 12 less than the original number.
So first number is x-12.
Second number added is 12 more than the original number.
So second number is x+12.
Now we are given that the result of adding all three numbers is 15.
Converting the information given into equation, we have:
original number + first number + second number =15

Adding like terms,

dividing both sides by 3,
x=5
Answer: So the original number that Mike thought was 5.
It is 234 because .567 are all decimals
Answer:
41+84=125 so therefore your answer is 125.
Answer: the area of the shaded region is 21.5 cm²
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Diameter of circle = 10 cm
Radius = diameter/2 = 10/2 = 5 cm
Area of circle = 3.14 × 5² = 78.5 cm²
The length of each side of the square is 10 cm. The area of the square would be
10² = 100 cm²
Therefore, the area of the shaded region would be
100 - 78.5 = 21.5 cm²
Answer:
b. 2,924
Step-by-step explanation:
Write and solve a proportion.
24 / 1032 = 68 / x
24x = 70176
x = 2924
