Answer:
6 x 108 in scientific notation
Step-by-step explanation:
Answer:
I do know that y = 3 and that x = -2, so any system that has that solution is correct.
Step-by-step explanation:
Multiplying the second equation by -2 and adding the equations will cancel out the x variable. The remaining equation is:
10y = 30. Therefore, y must be 3. Substituting y in for the first equation, we get:
6x + 6 = -6. That means x must be -2. I checked my work with the second equation:
-6 - 12 = -18.
The system results in a true statement, so the answer is y = 3 and x = -2.

<span>The 2 given numbers are 2.65 and 2.66
x = number between the given numbers
in a number line, 2.655 is the number in between both numbers.
- 2.65 – 2.651 – 2.652 – 2.653 – 2.654 – 2.655 – 2.656 – 2.657 – 2.658 – 2.659 – 2.66 -
Notice the given number line illustration, the midpoint of 2.65 and 2.66
numbers is 2.655.
Therefore, x = 2.655</span>
Answer:
Step-by-step explanation:
The altitude falls in the middle of the line.
So, the point at which it falls in the bottom line is the midpoint, so the length of the blue triangle would be 6/2 = 3
So, the blue triangle has length of 3 and height of H and hypotenuse of 10.
Now, we will use Pythagorean Theorem to solve for H. The theorem is:
Leg^2 + Another Leg^2 = Hypotenuse^2
We know one leg of the triangle is 3 and another leg is H and hypotenuse is 10, so we substitute and solve:
This is the exact answer for H
