Answer:

x= 6

Step-by-step explanation:

Step 1: Write equation

2x - 5 = 7

Step 2: Solve for x

Add 5 to both sides: 2x = 12

Divide both sides by 2: x= 6

Step 3: Check

Plug in x to verify if it's a solution.

2(6) - 5 = 7

12 - 5 = 7

7 = 7

Casey buys a bracelet. She pays for the bracelet and pays $0.72 $0.72dollar sign, 0, point, 72 in sales tax. The sales tax rate

Bogdan [553]

To find your answer you could type in the cost and multiply it by the tax rate, so $0.72 X $0.06(The tax rate )= $0.0432

You then subtract 0.0432 from 0.72 and get 0.6768

rounded it would be $0.68

Hope this is right..

Distance formula= [(x2-x1)^2 + (y2-y1)^2]^1/2
Origin= white house = (0,0)
Capitol= (2300,800)
Put the value,
(2300² + 800² )^1/2
= 2435 meters
Thus distance is 2435 m

Determine the amount needed such that when it comes time for retirement, an individual can make monthly withdraws in the amount

DochEvi [55]

Lets solve the problem through compound interest formula,

The number of months are 360

The account pay interest rate is 5.1 %compounded monthly.

The amount withdraws each month is $2154

The value of n is 360.

The value of is i is 5.1%

So,

$P = A [(1+i)^n]-1/i(1+i)^n\\\\P = $2,154 [(1+(0.051/12))^30*12] - 1 / (0.051/12)(1+(0.051/12))^30*12\\\\P = $396,721.78$

Hence the value of principal is $396721.78
