Help ..<br><br><br><br> 3(x+2)=5x+1-2x+5
Hunter-Best [27]

Answer:

All real numbers are solutions

Step-by-step explanation:

Let's solve your equation step-by-step

3(x+2)=5x+1−2x+5

Step 1: Simplify both sides of the equation

3(x+2)=5x+1−2x+5

(3)(x)+(3)(2)=5x+1+−2x+5(Distribute)

3x+6=5x+1+−2x+5

3x+6=(5x+−2x)+(1+5)(Combine Like Terms)

3x+6=3x+6

3x+6=3x+6

Step 2: Subtract 3x from both sides

3x+6−3x=3x+6−3x

6=6

Step 3: Subtract 6 from both sides

6−6=6−6

0=0

The number of customers that visit a local small business is 51,200 and has been continuously declining at a rate of 3.8% each y
Hunter-Best [27]

Answer:

Final amount of customers =30141.44

Step-by-step explanation:

Amount of customer remaining

A= p(1-r/n)^(nt)

P= initial amount of customers

R= rate but it's a negative rate

N= number of times

T= number of years

A= final amount of customers

A= p(1-r/n)^(nt)

A= 51200(1-0.038/14)^(14*14)

A= 51200(1-0.0027)^196

A= 51200(0.9973)^196

A= 51200(0.5887)

A= 30141.44
