We know that an hour has 60 minutes. She took 20 minutes to do one batch so we can see how many batches she makes with dividing 60 by 20. This would give us 3 batches per hour. Now we know she makes 8 frosted cookies per 20 minutes so we multiply 8 by 6 (2 hours as 20 min) and it would give us 48 frosted cookies

You want to save for retirement. assuming you are now 25 years old and you want to retire at age 50, you have 25 years to watch
mr_godi [17]

Answer:

4250

Step-by-step explanation:

0.13 = 13%

1000×0.13=130
130×25= 3250 + 1000 = 4250

What I did:

You have to turn the percent to a decimal first

Then multiply the decimal by the first investment amount (1000)

then multiply that by the years that you have before retirement
You add that amount plus the 1000 you have started with

PLEASE HELP SOLVE FOR ‘X’!!!
antoniya [11.8K]

Answer:

x= 10

Step-by-step explanation:

1/5 x -2/3 = 4/3

Add 2/3 to each side

1/5x -2/3 +2/3 = 4/3 +2/3

1/5x = 6/3

1/5x = 2

Multiply each side by 5

1/5x * 5 = 2*5

x = 10
