100p = £1
100 divided by 4 = 25
1 pen cost 25p

25p x 7 pens = 175p

175p = £1.75p

Ans is £1.75p

Mashutka [201]

Answer:

Fraction Form: \frac{2187}{4000000}

Decimal Form: 0.000547

Step-by-step explanation:

=\frac{5}{256} * \frac{3}{5}^1^2 / \frac{3}{5}^5

\frac{3}{5}^1^2/\frac{3}{5}^5=\frac{2187}{78125}

=\frac{5}{256}*\frac{2187}{78125}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}

\frac{5*2187}{256*78125}

\mathrm{Factor\:the\:number:\:}\:78125=5\cdot \:15625

=\frac{5*2187}{256*5*15625}

\mathrm{Cancel\:the\:common\:factor:}\:5

=\frac{2187}{256*15625}

\mathrm{Multiply\:the\:numbers:}\:256\cdot \:15625=4000000

\frac{2187}{4000000}

6x^2+x-12 in factored form
pychu [463]
6x²+x-12

the first thing we need to do is find 2 numbers that add up to equal the middle term (1) but multiply together to get a product of -72 (-12*6)

two numbers that would fit this is 9 and -8
so now we placed 9x and -8x in place of the middle term

6x²+9x-8x-12

now we look for whats common between the first two numbers and divide them out

6x²+9x = 3x(2x+3)

now we do the same with the last two numbers

-8x-12 = -4(2x+3)

notice how the numbers in brackets are the same (2x+3)
we will keep (2x+3) and then combine the numbers on the outside

once we do that you should get an answer of 

(3x-4)(2x+3)

hope this helped!

At Computer Central, the cost of renting a computer is $45 plus $35 per day. The total cost can be represented by the equation y
Thepotemich [5.8K]
Simple, since your equation is y=35x+45, it's quite simple to see what is the y-intercept.
It's written in y=mx+b form, the b being the y-intercept.

Thus, your y-intercept, is 45.
