Answer:

1) Save means adds and costs means subtraction

2) the minus sign goes with the 242 since thats the cost

3)12w + 62 = 242

4) 12w + 62 = 242

             -62    -62

12w = 180

/12        /12

w = 15

Solve the equation by finding square roots. To start, remember to isolate x^2. Equation= x^2+4=20
prohojiy [21]
Get the equation simplified. Subtract 4 by each side.
20-4= 16
and the square root of 16, is 4. 
Plug it in to check. 
(4)^2+4=20
16+4=20
20=20

Ultimately your final answer is X=4

3. Bob the Builder wants to earn an annual rate of 10% on his investments,
mamaluj [8]

Answer:

He should pay $2,790.7.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.

After t years, the total amount of money is:

T = E + P

In this question:

Rate of 10%, so I = 0.1.

9 months, so t = \frac{9}{12} = 0.75

How much should he pay for a note that will be worth $3,000 in 9 months?

We have to find P for which T = 3000. So

T = E + P

3000 = E + P

E = 3000 - P

Then

E = P*I*t

3000 - P = P*0.1*0.75

1.075P = 3000

P = \frac{3000}{1.075}

P = 2790.7

He should pay $2,790.7.
