<em>while the two were at the movies Katie spent $40.00</em>
Answer:
$23.75
Step-by-step explanation:
divide $28.50 by 6 to find the price for 1 bag which is $4.75 then multiply $4.75 by 5 and that equals $23.75
Step by step:
GR-8 = 34x - 12
• move variable to left hand side
-34x + gr -8 = - 12
• change expression and move to right side
-34x = - 12 - gr - 8
• calculate sum
-34x = - 4 - gr
• divide both sides
X = 2/17 + 1/34gr
And there’s your answer :)
Answer:
x = -1 ± 2i
Step-by-step explanation:
The standard form of a quadratic equation is ax² + bx + c = 0, and the quadratic formula is x= [−b ± √(b
² - 4ac) ] / 2a
In this case, a = 1, b = 2 and c = 5. Now you have to substitute in the quadratic formula:
x= [−b ± √(b
² - 4ac) ] / 2a
x= [−2 ± √(2
² - 4*1*5) ] / 2*1
x= [−2 ± √(4 - 20) ] / 2
x= [−2 ± √(-16) ] / 2
Since the square root is negative, you have to use imaginary numbers to continue solving the equation. Remmber that √(-1) = i.
x= [−2 ± √(-16) ] / 2
x= [−2 ± √(16)i ] / 2
x= [−2 ± 4i ] / 2
x1 = [−2 + 4i ] / 2
x1 = -1 + 2i
x2 = [−2 - 4i ] / 2
x2 = -1 - 2i
So the answers of x are -1 ± 2i
