Answer: 
= 
Step-by-step explanation:
let the number be x , then :
six added to twice the sum of a number and four means :
one half of the difference of three and the number means :
combining the two , we have
=
Most of the graphing resources used shows that the graph is translated up by 3.25 (3 + 1/4). If you add the 3 and the 1/4, you get the equation of a line:
f(x) = x + 3.25,
which means that the graph of f(x)= x now has a y intercept of 3.25.
The graphs are below. The red line represents f(x) = x, and the green line represents (x+3)+1/4. Hope this helps!
The answer would be A) 2,640.
In order to find this we must first find an amount of people per square feet. Since we are given that 10 people fit in a 5x5 square, we know that 10 people fit in 25 square feet. This will be the basis for our final calculation.
Now we need to find how many square feet we have. Since it is a quarter of a mile long, we'll divide the number of feet in a mile by 4.
5,280/4 = 1320.
Now we take the length and multiply it by the width, which is 5ft.
1320 * 5 = 6,600 square feet.
So we now know the size of the crowd. We can use that and multiply it by the factor that we found at the start to find the number of people.
6,600 square feet * 10 people/ 25 square feet = 2,640 people.
Answer:
A. x=0
Step-by-step explanation:
x+20+10x=20+9x
cancel equal terms
x+10x+9x
add x to 10x
11x=9x
move variable to left
11x-9x=0
subtract 11x to 9x
2x=0
divide Both sides by 2
x=0
