Answer:

Jan brought 44 cookies

Step-by-step explanation:

To solve this problem, we need to work backwards. First, we have 10 cookies left at the end of the day. At lunch, she gave away 12 cookies. This means that Ms. Jan had 22 cookies at lunch since  

10 + 12 = 22

In the morning, Ms. Jan gave out half of her cookies. This means that she started with twice as many cookies as she had at the beginning of lunch.  

22  x 2 = 44

Ms. Jan brought 44 cookies.

Maksim231197 [3]

Answer:

B. 5x + 25 > 75

Step-by-step explanation:

Points available = 25

Additional points earned per puzzle =5

He will advance to the next round if his score is over 75 points.

This means, he will move unto the next stage of his points exceeds 75 or greater than 75

The inequality is:

25 + 5x > 75

It can also be written as

5x + 25 > 75

The correct answer is B. 5x + 25 > 75

5x + 25 > 75

5x > 75 - 25

5x > 50

x > 50 / 5

x > 10

A. 5x + 25 < 75

B. 5x + 25 > 75

C. 25x + 5 > 75

D. 5x + 75 < 25

Elodia [21]

Answer:

1704.74 = P

Step-by-step explanation:

The formula for compound interest is

A = P(1+r/n) ^nt  where

A is the amount in the account

P is the principle

r is the interest rate

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

t is the time in years

2000 = P (1+.04/12)^12*4

2000 = P (1.003333333)^48

Divide each side by (1.003333333)^48

2000/  (1.003333333)^48= P (1.003333333)^48/ (1.003333333)^48

1704.74110 = P

Rounding to the nearest cent

1704.74 = P
