What single decimal multiplier would you use to decrease by 6% followed by a 9% decrease?
Tom [10]
<h3>Answer: 0.8554</h3>

==========================================

Explanation:

A 6% decrease means the multiplier is 1-0.06 = 0.94

A 9% decrease means the multiplier is 1-0.09 = 0.91

Multiply those results: 0.94*0.91 = 0.8554

----------------

Extra Info:

The final price is 85.54% of the original price after the two discounts are applied (in any order). This represents a total discount of 100% - 85.54% = 14.46%

3 (x-4) = 12x<br><br> What is the value of x.<br> Will give brainliest to first answer
diamong [38]

Answer:

x = -\frac{4}{3}

Step-by-step explanation:

Distributive Property:

3 (x - 4) = 12x

3x - 12 = 12x

Combine like terms and isolate the variable:

3x - 12 = 12x

-12 = 9x

-\frac{4}{3} = x

x = -\frac{4}{3}

Solve the inequality −x/2&lt;4
FinnZ [79.3K]

Isolate the x. First, multiply 2 to both sides

-x/2(2) < 4(2)

-x < 4(2)

-x < 8

Isolate the x. Divide - 1 to both sides (because you are dividing a negative number, flip the sign).

-x/ -1 < 8/-1

x > -8 is your answer

hope this helps
