Answer:
Step-by-step explanation:
- Initial number of marbles = 120
- Lost at every game = 5
- Stolen by a squirrel = 3
- Left = less than 10
<u>Let the number of games be x</u>
- then lost marbles = 5x
- stolen marbles = 3x
<u>Inequality:</u>
- 120 - 5x - 3x < 10
- 120 - 8x < 10
- 110 < 8x
- x > 110/8
- x > 13 rounded down
<u>Since there should be more than 0 left, another inequality for it:</u>
- 120 - 8x > 0
- 120 > 8x
- x < 15
So 13 < x < 15, which leaves us with 14
Answer:
0.200
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*x-4-(-4*x-2)=0
Step by step solution :
STEP 1
1.1 Pull out like factors :
10x - 2 = 2 • (5x - 1)
STEP 2
2.1 Solve : 2 = 0
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : 5x-1 = 0
Add 1 to both sides of the equation :
5x = 1
Divide both sides of the equation by 5:
x = 1/5 = 0.200
solution:
x = 1/5 = 0.200
The correct answer is: <span>a $100,000 life insurance policy at $0.55 per $1000 per month (more economical)
</span>
Explanation:
(1)<span>a $100,000 life insurance policy at $0.55 per $1000 per month
It means:
$0.55*100*12 = $660 [There are 100 thousands in $100000 and there are 12 months in the year]
(2)</span><span>a $100,000 life insurance policy at $170 per quarter.
It means:
$170*4 = $680 [There are 4 quarters in a year]
As $680 > $660 therefore Option (A) is the economical option.</span>
