X = 5
You first have to use Pythagorean Theorem to find the side lengths of the triangle with the hypotenuse of 10. The side lengths are 5sqrt2.
Now do Pythagorean theorem again to find the side length is 5
ANSWER
EXPLANATION
If y varies directly with x, we write the mathematical statement;
When we introduce the constant of proportionality k, then we write the equation,
If y is 2.5 when x is 5,then we have;
The equation of variation then becomes;
when x=14,
C. the values can be added after making a conversion of units because they both measure length.
Answer:
1/10
Step-by-step explanation:
5/20 x 8/20 = 1/10
5x - 9 = 26
5x - 9 + 9 = 26 + 9
5x = 35
5x/5 = 35/5
X = 7
