Mathematics

Answer:

1. Solve the equation using addition or subtraction.

4=q+13

Taking like terms on one side, we get

4-13=q

=> -9=q

or q=-9    (option C)

2. Solve the equation using addition or subtraction.  

5.5= -2+d

Taking like terms on one side, we get

5.5+2=d

So, d=7.5    (option B)

3. Solve the equation using multiplication or division

-7y=28

Dividing both sides by 7, we get

-y=4

or y=-4    (option A)

4. Solve the equation using multiplication or division

-13=\frac{m}{-5}

Cross multiplying -13 and -5 to get the value of m

m=(-13)(-5)

m= 65      (option C)

Jill invested $20,000 in an account that earned 5.5% annual interest, compounded annually. What is the value of this account aft
noname [10]

The value of this account in 10 years is given by the formula:

FV = P*(1+r)^t

where FV is the future value in the account after 10 years(to be calculated)

P is the principal invested at the beginning

r is the interest rate and

t is the time horizon in years

Given, Invested Amount (P) = 20,000

Interest rate (r) = 5.5% = 0.055

Time horizon (t) = 10 years = 10

Substituting the formula, FV = 20,000*(1+0.055)^10 = 20,000*1.055^10 = 20,000*1.708144458 =  34,162.89

The value of this account after 10 years =$34,162.89 (Rounded to the nearest cent)
