She will pay $1.50 for the hairbrush and her mum paid $1.50 as well
For this case we propose a rule of three:
page ----------> hour
x ---------------------------------> 1 hour
Where the variable x is the number of pages written in one hour.
Thus, Ophelia types 2 pages in 1 hour.
Answer:
Ophelia types 2 pages in 1 hour.
The solutions for the quadratic equation 9x² - 6x + 5 = 0 are A. 2 complex roots
To determine the the type of roots the quadratic equation 9x² - 6x + 5 = 0, we use the quadratic formula to find the roots.
So, for a quadratic equation ax + bx + c = 0, the roots are
With a = 9, b = -6 and c = 5, the roots of our equation are
Since the roots of the equation are (1 + 2i)/3 and (1 - 2i)/3, there are 2 complex roots.
So, the solutions for the quadratic equation 9x² - 6x + 5 = 0 are A. 2 complex roots

Answer:
Step-by-step explanation:
In order to solve for "x", we must remember the following properties:
- The Subtraction property of Equality states that:
If , then
- The Division property of Equality states that:
If , then
Therefore, knowing these properties, we can solve for "x" to find its value.
First, we need to subtract from both sides of the equation. Then:
And finally, we can divide both sides of the equation by 6. Then we get:
<span>B. The 4 in the tens place is 10 times the value of the 4 in the ones place
4 x 10 = 40
</span><span>D. The 4 in the hundreds place is times the value of the 4 in the tens place.
</span>40 x 10 = 400
