Answer:
3x+9 < - 42
Step-by-step explanation:
Answer:
23.3
Step-by-step explanation:
Use phyth. Thm.
a^2 + b^2 = c^2
A and B are the side lengths, and C is the hypotenuse. The hypotenuse is across the right angle.
Since you only have one side length and the hypotenuse this what your equation will look like:
30^2 + x^2 = 38^2
900 + x^ = 1444
544 = x^2
x = roughly 23.3
1495-400=1095
1095=15x
x=73
X: number of seats
Using a theorem (yes i forgot the name of the theorem), we know that because the angles opposite of the sides are congruent, the sides must be congruent aswell. Therefore:
3x - 24 = x + 10
Now solve, starting by using the addition and subtraction properties of equality:
3x - 24 + 24 = x + 10 + 24
3x = x + 34
3x - x = x - x + 34
2x = 34
Now, use the division property of equality:
(2x)/2 = (34)/2
x = 17
Therefore, x = 17.
