Equation at the end of step1: (7x + 18) (4) - 4x = 0 2 STEP2:Equation at the end of step 2 2 • (7x + 18) - 4x = 0 STEP3:STEP4:Pulling out like terms

4.1 Pull out like factors :

10x + 36 = 2 • (5x + 18)

Equation at the end of step4: 2 • (5x + 18) = 0 STEP5:Equations which are never true:

5.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

5.2 Solve : 5x+18 = 0

Subtract 18 from both sides of the equation :

5x = -18

Divide both sides of the equation by 5:

x = -18/5 = -3.600

Jamie is rolling two dice. What is the probability that she will not roll a 5 on either die?

Ira Lisetskai [31]

Answer:

10/12

Step-by-step explanation:

Since there are 6 sides on each die, and 2 dice, there are 12 choices. There are two fives so we subtract that from 12. The probability that Jamie will not roll a 5 on either die is 10 out of 12. I hope this helps! Please mark me brainliest!

Jamal deposits $2,500 into each of two savings accounts.

Bingel [31]

Account one will have $2800.
Account two will have $2875

And just so you can know how I figured it out if you times 4 x 3 that is 12 and 12% of 2500 is 300 and then add that to the initial amount and that’s how I got that one. And you do the same thing with the other one and do 5×3 and that is 15 and 50% of 2500 is 375 and that’s how I got the other answer

Ms. Whodunit needs $15 000 to go on her dream vacation in four years. How much

lisov135 [29]

For each situation, we have that:

11) Using compound interest, it is found that she needs to invest $9,781.11 now.

12) Using the future value formula, it is found that you will have $728,753 after 48 years.

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

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

In which:

A(t) is the amount of money after t years.

P is the principal(the initial sum of money).

r is the interest rate(as a decimal value).

n is the number of times that interest is compounded per year.

For this problem, the parameters are given as follows:

A(t) = 15000, t = 4, r = 0.055, n = 2.

Hence we solve for P to find the amount that needs to be invested.

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

$15000 = P\left(1 + \frac{0.055}{2}\right)^{2 \times 8}$

$(1.0275)^{16}P = 15000$

$P = \frac{15000}{(1.0275)^{16}}$

P = $9,718.11.

She needs to invest $9,781.11 now.

<h3>What is the future value formula?</h3>

It is given by:

$V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right]$

In which:

P is the payment.

n is the number of payments.

r is the interest rate.

For item 12, the parameters are given as follows:

P = 150, r = 0.07/12 = 0.005833, n = 48 x 12 = 576.

Hence the amount will be given by:

$V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right]$

$V(n) = 150\left[\frac{(1.005833)^{575}}{0.005833}\right]$

V(n) = $728,753.

You will have $728,753 after 48 years.
