A clothing store sold 4 times as many sweaters as coats. The difference in the sales was 300. How many of each were sold?

slava [35]

Sweater = 400
coats = 100
difference= 300
in an equation it would be
4x-x=300
so
3x=300
x=100
sweaters= 4x= 400
coats= x= 100

Encuentren dos números cuyo cociente sea -1 y que la resta del primero menos el segundo sea -3/2

miskamm [114]

Answer:

$\dfrac{3}{4}\ \text{and}\ \dfrac{-3}{4}$

Step-by-step explanation:

Find two numbers whose quotient is -1 and the subtraction of the first minus the second is -3/2

Let two numbers are x and y. When they are divided the quotient is -1. So,

$\dfrac{x}{y}=-1$

It can also be written as :

x = -y ....(1)

The subtraction of first minus the second is -3/2 .

$x-y=\dfrac{-3}{2}\ .....(2)$

Use equation (1) in (2),

$-y-y=\dfrac{-3}{2}\\\\-2y=\dfrac{-3}{2}\\\\y=\dfrac{3}{4}$

From equation (1) : $x=\dfrac{-3}{4}$

Hence, two numbers are $\dfrac{3}{4}\ \text{and}\ \dfrac{-3}{4}$ .

Write the slope-intercept form of the equation of each line. 9x-7y=-7

makkiz [27]

Slope intercept form is y = mx + b.....so lets solve for y

9x - 7y = -7 .....subtract 9x from both sides
-7y = -9x - 7...now we divide both sides by -7
y = 9/7x + 1 <==
