o-na [289]

They must sell, 30 cups of lemonade. How I got my answer.

Since it cost $1.20 to start, and a cup of lemonade cost $0.6 to make and there selling them at $0.10 each. So we know they are making a $0.4 profit off of each cup of lemonade. We now have to multiply 4×30=120.

I hope this helps!

What is an equation of the line that passes through the point (−1,6) and is parallel to the line 2x+y=9

Alex73 [517]

Answer:

2x + y = 4

Step-by-step explanation:

2x + y = 9 => y = -2x + 9

Parallel lines have the same slope so m = -2

Given (-1,6)

y = mx + b

6 = -2(-1) + b

6 = 2 + b

b = 4

so y = -2x + 4 or 2x + y = 4

Given x(y + 2) = 3x + y, express y in terms of x.

vodka [1.7K]

Answer:

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

Step-by-step explanation:

Given

x(y + 2) = 3x + y ← distribute parenthesis on left side

xy + 2x = 3x + y ( subtract 2x from both sides )

xy = x + y ( subtract y from both sides )

xy - y = x ← factor out y from each term on the left side )

y(x - 1) = x ← divide both sides by (x - 1)

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

One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K−273)+32. What is the temperature in Kelvin corr

DiKsa [7]

Answer:

The temperature in Kelvin corresponding to F degrees Fahrenheit is $K=\frac{F-32}{95}+273$

Step-by-step explanation:

Given : One can convert temperature from Kelvin into Fahrenheit using the formula $F=95(K-273)+32$ .

To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?

Solution :

Temperature from Kelvin into Fahrenheit is given by,

$F=95(K-273)+32$

Writing Kelvin in terms of Fahrenheit,

Subtract 32 both side,

$F-32=95(K-273)$

Divide by 95 both side,

$\frac{F-32}{95}=K-273$

Add 273 both side,

$\frac{F-32}{95}+273=K$

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is $K=\frac{F-32}{95}+273$
