Adam is 4 years older than Tara. Five years ago the sum of their ages was 48. Use algebraic equations to represent the situation

lord [1]

Answer:

Tara is 27 and Adam is 31.

Step-by-step explanation:

Tara: x years old

Adam: x+4

Subtract the five years to get their current age

x-5 and x+4-5

x-5 and x-1

(x-5) + (x-1) = 48

x-5 + x-1 = 48

2x - 6 = 48

2x= 48+6

2x= 54

x= 27

Tara is 27 and Adam is 31

Expand $\bold{2\left(a+2b\right): \ 2a+4b}$

= $\bold{2a+4b-a-2b}$

Simplify $\bold{2a+4b-a-2b: \ a+2b}$

= $\bold{a+2b}$

Can someone help me with answer C? its the last one i need

Using the monthly payment formula, it is found that her down payment should be of $1,419.

<h3>What is the monthly payment formula?</h3>

It is given by:

$A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}$

In which:

P is the initial amount.

r is the interest rate.

n is the number of payments.

For this problem, the parameters are:

A = 250, r = 0.072, n = 72.

Hence:

r/12 = 0.072/12 = 0.006.

We solve for P to find the total amount of the monthly payments, hence:

$A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}$

$P\frac{0.006(1.006)^{72}}{(1.006)^{72}-1} = 250$

0.0171452057P = 250

P = 250/0.0171452057

P = $14,581.

The total payment is of $16,000, hence her down payment should be of:

16000 - 14581 = $1,419.
