Answer:
its 1,200 - 660= 540
Step-by-step explanation:
Answer:
Step-by-step explanation:
Standard form of a linear equation: 
(where A, B and C are integers, and A shouldn't be negative)
Given equation:
Multiply both sides by 8:
Subtract 8y from both sides:
Subtract 24 from both sides:
In standard form:
Remark
I'm going to assume that it is just the 0.41 that is doing the repeating. If it is not leave me a note.
Solution
The trick is to call x = 3.4141414141 ....
then multiply by 100
100 x = 341.4141414141 ............ Now write the original decimal underneath.
<u>. . . x = 3.414141414141 ......</u>...... Subtract
99 x = 338 That's all that's left. The decimal part cancels out.
x = 338 / 99 Fractional answer.
x = 3 39/99
x = 3 13/33 If this isn't one of your answers, leave me a note.
Answer:
89 meters
Step-by-step explanation:
We know it's 9 + "the height of the triangle".
Fortunately, the height of the triangle (let's call it y) can be computed from:
y^2 + 18^2 = 82^2 (Pythagoras theorem).
y^2 = 82^2 - 18^2 = 6724 - 324 = 6400
y = 80 (or y = -80 but it doesn't make sense in geometry).
so x = y + 9 = 89;
