Select the correct description for the expression 5(x-7) A the product of a number and a sum
B the quotient of a difference and a number
C the quotient of a sum and a number
D The product of a number and a difference
PLSSS HELP

The correct answer is D

Step-by-step explanation:

My reason for giving this answer is because this problem is written in expression form. Since there is a variable in the expression, You cannot solve X-7 without outside information on the value of X. So D would be the answer because The answer to a multiplication problem is called the product, Then the answer to a subtraction problem is a difference. Answer D says "The product of a number and a difference", Which would mean multiplication and subtraction.

Hope this helped!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
