Step-by-step explanation:
set 3 no is ,x _ I ,x,x+1
X-1 + x + x + I = 84
3 X = 84
X= 84/ 3
X= 2 8
largest no is 29
It appears that none of your option choices are correct,, are you sure you copied them right ? I will show you how to solve this and how I got my answer.
The first step for solving this is to add the numbers in the parenthesis.
3 × 11 × 2 - 14 ÷ 7
Divide -14 by 7.
3 × 11 × 2 - 2
Divide the first 3 numbers together.
66 - 2
Subtract the numbers together to get your final answer.
64

4 * 42 + 55 * x / ( 4 + x ) = 50.
The answer of x comes out to be 6.4. Which means that the truck will have to travel around 6.4 miles at an average speed of 55 miles to make it 50.
Well to understand how i constructed its equation is very simple. I equated the total average speeds answer to 50 and just calculated the average speeds with the help of algebra where x is the number of miles at 55 mph.
Answer:
B) a²-(2*4)
Step-by-step explanation:
Since we are looking for the gray area only, we need to find the total area of the figure, but subtract that from the area of the unshaded area.
The total area of the figure is a*a=a²
The area of the unshaded figure is 2*4=8 units^2
This means the gray area is a²-(2*4) units^2, making B correct
