What is the GCF of (8x-6) <br><br>sos T-T

makvit [3.9K]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find the G.C.F. of 8x-6.

$\triangle~\fbox{\bf{KEY:}}$

G.C.F. stands for Greatest Common Factor.

So what is the G.C.F. of 8x-6? We can list all of their common factors and then select the greatest one, like so:

$\longmapsto\bf{Factors\;of\;8x:}$ 1, 2, 4, 8, x

$\longmapsto\bf{Factors\;of\;-6:}$ -1, 1, 2, -3, 3, -6, 6

So the GCF is:

2

Now, we can also factor it out by placing it outside the parentheses ():

2(4x-3)

See, we factored it out by dividing both terms of the expression by the G.C.F.

$\ddot\bigstar$ Remember this...

$\fbox{\bf{We\;factor\;out\;the\;G.C.F.\;by\;dividing\;all\;the\;terms\;of\;the\;expression\;by\;it}}$

Hope this helps you out! :D

if a one bedroom apartment that rents for $450 in Detroit rents for 250% of that price in manhattan, what is the rent in Manhatt

lesya [120]

Answer:

$1125

Step-by-step explanation:

To find percentage of something, we always take the percentage, convert it to decimal by dividing by 100, and then multiply that decimal with the number given.

Here, we want to find 250% of $450. First, lets convert 250% to decimal:

250/100 = 2.5

So, 250% = 2.5

Now we multiply this with $450 to find rent in Manhattan:

2.5 * 450 = $1125

That's a whooping price of $1125 in Manhattan!!
