The ratio of customers who purchase items with coupons to customers who don't use coupons is 6 to 16. If 9 customers use coupons
Irina-Kira [14]

Answer:

24 customers will not use coupons.

Step-by-step explanation:

Number of customers who use coupons = 9

Number of customers who don't use coupons = x

Ratio of customers who use coupons to customers who don't use coupons = 6:16

=\frac{6}{16}

\frac{9}{x}=\frac{6}{16}

x=\frac{9\times 16}{6}=24

24 customers will not use coupons.

When 5x^2 + 2= 4x is written in standard form, what are the values of a, b, and c
goblinko [34]

The standard form of a quadratic equation is

ax^{2}+bx+c=0,

where a, b, and c are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.

In this case, the given equation is

5x^{2}+2=4x

Since 4x is on the right side of the equation, we subtract that from both sides. The resulting equation is

5x^{2}-4x+2=0

Looking at the standard form equation ax^{2}+bx+c=0, we can see that

a=5, b=-4, c=0

What is the equation of the line in standard form?<br> 3x−y=−6 3x + y = 6 x + 6y = 9 x−6y=−9
lisabon 2012 [21]

The standard form: Ax + By = C

3x - y = -6  YES - A = 3, B = -1, C = -6

3x + y = 6   YES - A = 3, B = 1, C = 6

x + 6y = 9   YES - A = 1, B = 6, C = 9

x - 6y = -9   YES - A = 1, B = -6, C = -9
