Answer: the simplified expression is

2y^15/(3x^5z^12)

Step-by-step explanation:

The given expression is

(-8x^2y^8z^-5) / (12^4y^-7z^7)

To simplify the given expression, we would apply one of the rules of indices. It is expressed as follows

x^a ÷ x^b = x^(a - b)

Applying the above rule of indices, the expression becomes

(-8/12 × x^(2 - 7) × y^(8 - - 7) × z^ (- 5 - 7)

= - 2/3 × x^- 5 × y^15 × z^-12

= - 2/3x^- 5y^15z^-12

= 2y^15/(3x^5z^12)

*no parentheses in this equation
*exponent = 6^2
6^2=36
4+36+9•3-10
*multiplication = 9•3
9•3=27
4+36+27-10
*addition=4+36+27
4+36+27=67
67-10
*subtraction=67-10

Meredith invested $5,500 into an account that earned 5% interest per year. When she cashed out the investment to use it as a dow
shtirl [24]

Answer:

Step-by-step explanation:

Using I = PRT/100

where P = The principal amount invested = $5500

R = Rate of Interest =5%

T = Time (in years)

I = Interest = $7,739.05 - $5500 = $2239.05

Substituting the above values in the formula

I = PRT/100 becomes

2239.05 = 7,739.05 * 5 * t / 100 -------- Multiply 100 to both sides

2239.05 * 100 = 100 * 7739.05 * 5 * t / 100

223905 = 7739.05 * 5 * t

223905 = 38695.25t

Divide both sides by 38695.25t

223905/38695.25 = t

5.786369 = t

T = 5.79 (approximated)
