B cause if u add both of them alll of them they have different answer
Notice they are all right triangles. You will need Pythagorean theorem, which is a² + b² = c²
If you write down all the "equations" you can find, it is the following:
y² + 4² = x²
5² + y² = z²
x² + z² = 9²
Substitute them into one equation:
y² = x² - 4²
z² = 5² + (x² - 4²) <em>Notice that the y² is replaced with what you found </em><em>above</em>
x² + (5² + x² - 4²) = 9² <em>Notice that the z² is replaced with what's </em><em>above</em>
Now that it is just one line with one variable, you should be able to find value of x easily.
The answer is 6 if my calculations are correct.
Step-by-step explanation:
Rational expressions and rational equations can be useful tools for representing real life situations and for finding answers to real problems. In particular, they are quite good for describing distance-speed-time questions, and modeling multi-person work problems. Myra takes 2 hours to plant 500 flower bulbs.
Answer:
1 necklace is $19!
Step-by-step explanation:
4•$8=$32
$70-$32=$38
$38/2=$19
You cam solve this by using this method
2/27= 1/x you wil cross multiply and solve for x getting x=13
