LaTanya buys 5 yards of blue fabric and 8 yards of green fabric. The blue fabric costs $2 more per yard than the green fabric. She pays a total of $62. What would be the combined cost of 1 yard of blue fabric and 1 yard of green fabric? A.$10
B.$14
C.$9
D.$6

The answer would be $10

Step-by-step explanation:

To work out this problem it is necessary to have a look at the multiples of

5 and 8.

Multiples of 5 : 10-15-20-25-30

Multiples of 8: 16-24-32

The blue fabric costs $2 more than the green so : 5 yards x 6 = 30

The green fabric is $2 cheaper than the blue so: 8 yards x 4= 32

This amounts to 62 the total of the purchase.

The blue fabric costs $6 a yard and the green costs $ 4 .

i dont know sorry

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
