Answer: 
Step-by-step explanation:
FIrst find the square root of 81.
The square root of 81 is 9.
FInd the product of -1 and -3 by multiplying the -1 by -3.
-1 * -3 = 3
next find the square root of 4.
Now it said divide the square root of 81 which is 9 by the difference between 3 and 2 and the difference between 3 and 2 two is 1.
Thos means that the answer will be 9/1.
Answer:
$3.50 if they all equal the same amount.
Step-by-step explanation:
If six comic books are bought with $21, and we assume they are all the same amount of money, we would simply divide our cost ($21) by our quantity (6).
21/6 = 3.5
Therefore, the cost of one comic book equals $3.50.

Answer:
40 ft
Step-by-step explanation:
The post is 8/12 = 2/3 as tall as the shadow is long. We expect the same relationship holds for the tree.
tree height = (2/3)(shadow length) = (2/3)(60 ft) = 40 ft
The tree is 40 feet tall.
Answer:
x = 4y + 6
Step-by-step explanation:
x-4y=6
2x-8y=12
multiply 2 on both side in equation 1, and multiple - on both side in equation 2:
2x-4x=12
-2x+8y=-12
so the equation becomes:
4y=0
y=0
put the value of y in both of the equations:
x=6 equation 1
x=6 equation 2
so,
x = x
then,
x = 4y + 6 equation 1
-2 ( x - 4y ) = -12
x - 4y = -12/ -2
x - 4y = 6
x = 4y + 6
so the ans is:
x = 4y +6
Answer:
The perpendicular line would be y = 6
Step-by-step explanation:
In order to get this, we must first recognize that the equation given is a vertical line. If our new line is to be perpendicular to it, it must be a horizontal line. All horizontal lines are written as y = (a number). Since we have a point it goes through, we can get that value in the ordered pair. The ordered pair has a y value of 6, which means the equation would be y = 6
