Answer:

56,161

Step-by-step Thought Process:

Use the equation: a(1+r)^x to solve this problem. Let x= time in years, a= initial amount, and r= growth rate.

a(1+r)^x =  51368(1+0.018)^5

When you solve you get this number:

56,160.57516085

Round to the nearest whole number:

56,161

2. Graph each inequality on a number line:<br><br> 5x + 15 &lt; 0
Georgia [21]

Answer:

x < -3

Step-by-step explanation:

1. To put this inequality on a number line, we first must solve it.

Step 1: Subtract 15 from both sides.

  • 5x + 15 - 15 < 0 - 15
  • 5x < -15  

Step 2: Divide both sides by 5.

  • \frac{5x}{5}
  • x < -3

2. Now that we know x < -3, let's graph it!

  • Since it's less than, we make the number line point to the left, and we make the circle open.

2x -3&lt; -1 or -3x &lt; -15
pogonyaev

Answer:

x<1 or x>5

Step-by-step explanation:

2x -3< -1 or -3x < -15

Solve them separately then put them back together

2x-3 < -1

Add 3 to each side

2x-3+3<-1+3

2x<2

Divide by 2

2x/2 <2/2

x<1

-3x < -15

Divide each side by -3, remembering to flip the inequality

-3x/3 > -15/-3

x>5

Put them back together

x<1 or x>5

What is the radius of a circle with circumference 56 inches
pochemuha

Answer:

The answer is 8.91 or 8.9

Step-by-step explanation:

SInce the circumference is 56, you'll divide it by pi or 3.14. It's as if you're doing it backwards, but not always. After you divide it by 3.14, you'll get your diameter, or in this case, 17.8. Divide the diameter by 2 because the diameter is twice the radius. Eventually your final answer will be 8.91 or 8.9
