I'm going to do this two ways, one using a calculator and one not.
Let the total amount of his estate be x.
Equation and Solution
If you have a calculator with an a b/c key on it you can do this problem easily, or at least the fractional part will be easy.
First: develop the equation
(4/17) x + (7/13)x + 2/3 x + 2 000 000
Solve the equation
Use the a b/c key on your calculator if you have one. If not go down the second solution part. Put a fraction in as follows.
4 a b/c 17 + 7 a b/c 13 + 2 a b/c 3 =
You should get 1 r 16 r 51
What this translates into is 1 292 / 663 of x
or 955/663 x + 2000000
So the total of fhis estate is
(955/663) x + 2000000 <<<< answer In decimal form you get
1,44 x + 2000000 <<<< answer in decimal.
Note: you cannot solve this to the exact amount of his estate because the fractional amount exceeds x which assumed to be the total amount of his estate.
By hand
Find the ;lowest common denominator of 13 17 and 3. Since all of them are prime numbers the lowest common denominator is 13 * 17 * 3 = 663
\
Next set up the 3 fracttions so the denominator = 663
4 / 17 =( 4 * 13 * 3) / 663 = 156 / 663
7/13 = 7 * 17*3 / 663 = 357 / 663
2/3 = 2*13 * 17 / 663 = 442 / 663
Now add these up 156/663 + 357/663 + 442/663 = 955 / 663 This is irreducible
This fraction is over 1 so it cannot represent the total amount in his estate. It is too large.
(955/663)x + 2000000 <<<<<< fractional answer
1.44x + 2000000 < decimal answer.
Answer:
D
Step-by-step explanation:
Greater is to the right, equal to makes it a filled circle.
Answer:
48 units
Step-by-step explanation:
20 - 12 = 8
(8)(12) = 96
96/2 = 48 units

H = - 16 t² + 32 t + 9
The maximum height is at the vertex of the parabola:
t = - b / (2 a ) = - 32 : ( - 32 ) = 1 s
The ball will reach maximum height in 1 second.
h max = - 16 * 1² + 32 * 1 + 9 = - 16 + 32 + 9 = 25 m
The maximum height is 25 m.
For example x^2=25
Without x the expression wouldn't exist, it allows you to calculate unknowns for example in a physics experiment using v=u+at
