Answer:
x=3
Step-by-step explanation:
-4x-(-3-5x)=-3(2x-8)
-4x+3+5x=-6x+24
x+3=-6x+24
+6x +6x
7x+3=24
-3 -3
7x=21
/7 /7
x=3

Answer:
2.1l /7= .3 mi
Step-by-step explanation:
Given from the question
first fraction = 5/6
second fraction = 1/3
We're asked what's the difference between the fraction
First, we need to equalize the denominator to the same number. The first denominator is 6, the second denominator is 3. I'd like to make them both 6. So the second denominator needs to be multiplied by 2, so does the numerator
second fraction = 1/3
second fraction = (1 × 2)/(3 × 2)
second fraction = 2/6
Second, we have new fractions which have the same denominator. Calculate the difference
d = first fraction - second fraction
d = 5/6 - 2/6
d = 3/6
The red tape is 3/6 yard more than the green tape.

Answer:</h3>
x² -6x = -13 ⇒ x ∈ {3-2i, 2+2i}
<h3>
Step-by-step explanation:</h3>
To make a=1, divide the equation by the coefficient of x², which is 8.
... x² -6x = -13 . . . . . . your blanks are filled with -6 and -13
Now, to complete the square, add the square of half the x-coefficient:
... (-6/2)² = 9.
... x² -6x +9 = -4 . . . 9 added to both sides
... (x -3)² = -4 . . . . . rewrite as a square
... x -3 = ±2i . . . . . . take the square root
... x = 3 ±2i . . . . . . . add 3
The solutions are the complex numbers x = 3 ±2i.
