I would factor it or graph it
A simple algebraic equation can be utilized to solve this question. Ayana needs
yards of blue fabric for each scarf.
Step-by-step explanation:
Step 1; Assume the amount of purple fabric to be x for each scarf and the amount of blue fabric required for each scarf to be y. It says a total of six scarves are needed. It is given that a total of 10 yards of fabric is used i.e. the total of purple fabric and the blue fabric. So we can create an equation for this. As 6 scarves are needed we substitute x and y as 6x and 6y.
Total fabric used= 6x + 6y = 10 yards.
Step 2; It is given that for each and every scarf 1
yards of purple fabric is needed. So for 6 scarves a total of 6 * 1
yards is needed. So 6x becomes 6 * 1
yards.
6x = 6 * 1
yards = 6 *
=
yards of purple fabric.
Step 3; Now we solve for the amount of blue fabric needed.
6y = 10 -
=
= ![\frac{10}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B4%7D)
But the
yards is for 6 scarves to we divide it by 6 to get the material needed for a single scarf
y =
/6 =

=
=
yards = 0.4166 yards of blue fabric for each scarf.
This problem involves two unknowns, thus, it can be solved using two independent equations. We first assign a variable for each real number.
Let:
x = first real number
y = second real number
Two independent equations must then be set up which will come from the problem statement. The first equation is obtained from the statement that the average of the two real numbers is 41.375. The second equation then shows that the product of the two real numbers is equal to 1668. The equations are then:
(1) (x + y)/2 = 41.375
(2) x*y = 1668
We then express the variable y in terms of x, such that, y = 1668/x. This is then applied in equation 1 in order to have only a single variable in the equation. After doing mathematical operations, x is then calculated to be 34.75. This value of x is then substituted in the second equation to obtain y. Finally, the two real numbers have been determined to be x = 34.75 and y = 48.
