the five digit number:
let the first digit be x
x _ _ _ _
x 3x _ _ _
x -3x- 3x+1- 4x- 3x+1.5x
This is the structure of the digit:x -3x- 3x+1- 4x- 3x+1.5x
Answer:
Step-by-step explanation:
the answer is D
because when it England was officially found the counted as a kingdom
Answer:
Answer is 2a + 8 because 2 times a is 2a and 2 times 4 is 8
Part A
4 < 5 < 9 is given to us. Apply the square root to each term to end up with this inequality: sqrt(4) < sqrt(5) < sqrt(9)
So sqrt(5) is between <u>sqrt(4)</u> and <u>sqrt(9)</u>
-------------------
Part B
Simplify those two mentioned square roots
sqrt(4) = sqrt(2^2) = 2
sqrt(9) = sqrt(3^2) = 3
Therefore, sqrt(5) is also between <u>2</u> and <u>3</u>
We can see this through using a calculator: sqrt(5) = 2.23607 approximately
-----------------
Part C
We can now say:
2 < sqrt(5) < 3
Multiply all three sides by 6
6*2 < 6*sqrt(5) < 6*3
So the expression 6*sqrt(5) is between <u>6 x 2</u> and <u>6 x 3</u>
Sure enough, a calculator confirms this
6*sqrt(5) = 13.416408
since 6*2 = 12 and 6*3 = 18. We see that 13.416 is between 12 and 18.
If the resultant line is a straight line,it represents a
direct variation.
