Isabella is solving the equation 4x^2=13x-3 with the quadratic formula
laiz [17]

Answer:

x=(3,1/4)

Step-by-step explanation:

Be sure to use the formula...

-b + or - sqrt{b^{2} - 4ac } / 2a

- First, move all variables to one side (left) of the equation. You want one side to be equivalent to zero.

-Next, you need to find a, b, and c. This should be...

a=4

b=-13

c=3

- Knowing this, fill in these variable to go along with the formula. I cannot do this for you, as you should try it on your own. But, you should end up with the solution x= (3,1/4).

- Hope this helps! If you need a further explanation or help on any more problems please let me know, as I would be glad to help anytime.

Leah has meters of cloth, which she divides equally among her friends. Each friend gets meters of cloth.
Brrunno [24]

Answer: 6

Step-by-step explanation:

Here's the complete question:

Leah has 8 4/7 meters of cloth, which she divides equally among her friends. Each friend 10/7 gets meters of cloth. She distributed the cloth to ---- friends.

Total length of the cloth = 8 4/7m

Number of friends = Unknown

Amount of length gotten by each friend= 10/7

The number of friends that she shred the cloth among will be:

= Total length of cloth / Length gotten by each friend

= 8 4/7 ÷ 10/7

= 60/7 ÷ 10/7

= 6/7 × 7/10.

= 60/10

= 6.

It was shared among 6 friends
