\frac{1}{2} (x+12)=4x-1

Multiply  both sides by 2 :

\frac{1}{2}(x+12)*2 = 4x*2-1*2

x+12=8x-2

x+12-12=8x-2-12

x=8x-14

Subtract 8 x from both sides:

x-8x=8x-14-8x

-7x=-14

Divide both sides by -7 :

\frac{-7x}{-7} = \frac{-14}{7}

x = \frac{14}{7}

x = 2

Find the product.<br> (3n - 1)(7n-7)
slega [8]

Answer:

21n² - 28n + 7

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

3n(7n - 7) - 1(7n - 7) ← distribute both parenthesis

= 21n² - 21n - 7n + 7 ← collect like terms

= 21n² - 28n + 7

Emmanuel went to the store and
musickatia [10]

Answer:

$148.50

Step-by-step explanation

I solved this by using fractions.

x/450=33/100 is how I set up the problem. 33/100 represents 33%, while x/450 represents how much the jacket costs now.

I then went across and multiplied x by 100, and 450 by 33, which gave me 100x=14850. After this I divided each side by 100 to get 148.5, being the cost of the jacket.
