That is standard form. scientific notation would be 4.35x10^-4
<h2>Given :-</h2>
- Patrick had twice money at first
- Susan recived and Patrick spent some money
- The amount Susan received was 3 times as much as the amount Patrick spent
- At last they have same amount
<h3>To Find :-</h3>
<h2>Solution :-</h2>
At first Patrick had twice of Susan.
Hence,
He have 2 × 120 = $240
Let the money received be x
- x + 120 = 3(240 - x)
- x + 120 = 720 - 3x
- 3x + x = 720 - 120
- 4x = 720 - 120
- 4x = 600
- x = 600/4
- x = 150
Answer:
EK = 8
Step-by-step explanation:
Intersecting Chords Formula: a • b = c • d
BK * KD = EK * KC
4 * 10 = (x+1) * (x-2)
40 = x^2 +x-2x-2
40 = x^2 -x -2
0 = x^2 - x-2-40
0 = x^2 -x -42
Factor
0 = (x-7) (x+6)
Using the zero product property
x-7 = 0 x+6 =0
x=7 x=-6
X is not negative
x=7
EK = x+1
EK = 7+1
EK = 8
Answer: B
Step-by-step explanation: The first X was 1. If you add 1 too the 1/2 in the equation, its 1 & 1/2. theres only one graph that has 1 & 1/2, and its B
