Answer:
x = 9.6
Step-by-step explanation:
Before we can figure out what x is, we need to figure out what the unlabeled side is. To figure that out, multiply the hypotenuse (12) by the sine of the angle labeled (34)
12 * sin(34)
<em>sin(34) equals 0.559192903470747; I'll round it to 0.6 for convenience.</em>
12 * 0.6
<em>Now simply multiply 12 by 0.6 to get 7.2.</em>
The unlabeled side is approx. 7.2 units long.
Now we know what the unlabeled side is. Now, to find x, find the square root of 12 squared minus 7.2 squared.
x = √12² - 7.2²
<em>12 squared is 144; 7.2 squared is 51.84.</em>
x = √144 - 51.84
<em>Subtract 51.84 from 144 to get 92.16.</em>
x = √92.16
<em>The square root of 92.16 is 9.6 (on the spot!).</em>
x equals 9.6.
The solution to the system of equation are (0, -2) and (1, 0)
<h3>Solution to system of equations</h3>
System of equations are equations that has unknown and more than 1 equations.
Given the system of equations
y = x^2 + x – 2
y = 2x – 2
Equate both expressions
x^2 + x -2 = 2x - 2
x^2 - x = 0
x(x-1) = 0
x = 0 and x - 1 = 0
x = 0 and 1
If x = 0
y = 0 - 2 = -2
If x = 1
y = 2 - 2 = 0
Hence the solution to the system of equation are (0, -2) and (1, 0)

To figure this out, you have to figure out what Donovan scored.
Just divide his score (39 ÷ 50) and get 0.78.
Since we already knew this, we can figure out Marci's score. Since she score 88%, we can assume she scored somewhere in the 40's.
Once you figure out what her score was out of 50, divide it.
Your equation should look like this: 44 ÷ 50 = 0.88
This means that Marci answered 44 questions out of 50 questions correctly. (44/50)
Answer:
0.3
Step-by-step explanation:
Probability always adds up to 1 or 100%
in this case 0.2 + 0.5 = 0.7
1.0 - 0.7 = 0.3
hope this helps! :)
