9514 1404 393

Answer:

  x = 4

Step-by-step explanation:

The inverse variation means that when y goes up by a factor of 20/5 = 4, the value of x goes down by the same factor.

  x = 16/4

  x = 4

The future value (A) of a principal amount P compounded 12 times per year at rate r for t years is given by
  A = P·(1 + r/12)^(12t)

Substitute the given values and solve for t.
  3000 = 175·(1 + .03/12)^(12t)
Taking logarithms, this becomes
  log(3000) = log(175) + 12t·log(1.0025)
  (log(3000) -log(175))/(12·log(1.0025)) = t
  t ≈ 94.84

It will take 95 years for the balance to grow by a factor of 17 to $3000.

Ivenika [448]
Answer:22

step by step:
so we have PE(MD)(AS)
(for multiplication and division it depends on left to right, same for addition and subtraction)

this could be read as
30 - [(12/3)*2]

first you would do 12/3 which is 4
then you do 4*2 which is 8
last you do 30-8 which is 22

hope that helps :)

Use the Distributive Property to write an expression that is<br> equivalent to 4(y - 3).
Nonamiya [84]

Answer:

4y-12

Step-by-step explanation:

To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).

If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.
