How do you do number 2? Help please and thank you.
Dmitrij [34]

Answer:

{3,-1}

Step-by-step explanation:

m^2 -2m -3=0

What 2 numbers multiply to -3 and add to negative 2

-3* 1 = -3

-3 +1 =-2

(m-3) (m+1) =0

Using the zero product property

m-3 = 0  m+1 =0

m=3        m=-1

Wich equation gives the number of 1/3 inches that are in 5/6 inches
lara31 [8.8K]

Hello from MrBillDoesMath!

Answer:

(1/3) x = (5/6)


Discussion:

I think you are asking for this equation:

(1/3) x = (5/6) =>            multiply both sides by 3

(1/3) 3 x = (5/6) 3 =>      as (1/3) *3 = 1

x = 5*3/6

x= 15/6

x = 5/2 = 2.5

Thank you,

MrB

Which do you think will have a greater value, 1/8 of one pound gold or 1/4 of lead? Why?
Ivenika [448]
<span>if you multiply 1/8 by 4, the fraction become 4/32, and if you multiply 1/4 by 8 you get 8/32.Since both fractions have the same denominator, we can find which fraction has the greater value. Since 1/4(8/32) has a greater numerator, the 1 pound of lead will have a larger value.</span>
