What is 6(5j + 4 + 3j) after using distributive property. Please explain your answer.
Answer:
Step-by-step explanation:
30j + 24+ 18j
48j + 24
Answer:
48j+24
Step-by-step explanation:
6(5j + 4 + 3j)
when there is a number outside of the parenthesis you have to multiply everything in the parenthesis by that number
6x5j=30j
6x4=24
6x3j=18j
so now we are left with 30j+24+18j
the final step would be to combine like terms
the only like terms are 30j and 18j
30j+18j=48j
so the final answer is
48j+24
hope this helps (:

A music store is having a clearance sale. All items are discounted by 20%. What is the sale price of a radio that regularly costs $30?
Answer:
24
Step-by-step explanation:
You would first multiply 20% by $30. Then you would get 6 and subtract 6 from $30.
Answer:
$24
Step-by-step explanation:
Method 1: find 10% of 30 = 3 (just divide 30 by 10)
then double it to make 20% = 6
subtract 6 from 30 to give 24.
Method 2: 20% = 1/5
To find 1/5 of a number, divide it by 5.
30 divided by 5 = 6.
Then subtract 6 from 30 = 24.
Method 3: to decrease a number by 20% multiply it by 0.8.
30 x 0.8 = 24

A circle has a circumference of 16π yards. Find the area in terms of π (pi).
64 pi. Since the formula for the circumference of a cirlcle is: pi x diameter. The diameter of the circle would be 16. And the radius of that would be 8 since its half of 16. The formula to find the area is: pi x radius squared. So 8 squared pi would be 64 pi.
