If the expression ax(2x + y - 5) simplifies to 6x² +3xy - 15x, what is the value of a?
nata0808 [166]
Since:
ax(2x + y - 5) = 6x^2 +3xy - 15x,

we should factor X out of the second equation to find out the value of a:
6x^2 + 3xy - 15x =
x(6x + 3y - 15),

Now that we factored X out, to find a, we need to find the other common factor:

(6x + 3y - 15) / (2x + y - 5),

which is 3.

Hence the value of a is 3

Jenny reads 5/8 pages in 2/3 minutes what's the unit rate
LekaFEV [45]

Answer:

15/16 pages in a minute

Step-by-step explanation:

So to make a unit rate, you have to make the denominator 0. So (5/8)/(2/3) is 5/8*3/2 or 15/16. So that would be 15 pages in 16 minutes or 15/16 pages in a minute.
