Answer:
Step-by-step explanation:
Represent Anita's age by a and Basilo's by b.
Then a = b - 4.5, and 3(a + 6) = 36 (where I have "invented" the value 3).
Substituting b - 4.5 for a in 3a + 18 = 36: 3(b - 4.5) + 18 = 36
Performing the indicated multiplication:
3b - 13.5 + 18 = 36, or
3b + 13.5 = 18, or
b = 18 - 13.5 = 4.5
Basilo is 4.5 years old, whereas Anita is 9 years old.
If this is not correct, please double-check to ensure that you have copied this problem down correctly.
For x.
All the right triangles are similar, so
.. hypotenuse/(short side) = x/6 = 6/(x -9)
Multiplying by the product of denominators gives
.. x(x -9) = 36
Two factors of 36 that differ by 9 are 12 and 3, so we have
.. x = 12
For y, we can use the Pythagorean theorem.
y^2 +6^2 = 12^2
y^2 = 144 -36 = 108
y = √108 = √(36*3)
y = 6√3

Answer:
x = 4
Step-by-step explanation:
2.25x=1.5x+6
divide on both sides by 1.5x which equals
1.5x=6
divide both sides by 1.5
x=4
A) There was no change in the number of students on honor roll from one year to the next. This is noticeable because 200/1000 = .2 just as 20%/100% = .2 or 20/100 = .2. So there never was a change!
