Solve for k 4.5+1.5k=18−3k

sertanlavr [38]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{k = 3}}}}}$

Step-by-step explanation:

$\sf{4.5 + 1.5k = 18 - 3k}$

Move 3k to left hand side and change it's sign

Similarly, move 4.5 to right hand side and change it's sign

$\longrightarrow{ \sf{1.5k + 3k = 18 - 4.5}}$

Collect like terms

$\longrightarrow{ \sf{4.5k = 18 - 4.5}}$

Subtract 4.5 from 18

$\longrightarrow{ \sf{4.5k = 13.5}}$

Divide both sides by 4.5

$\longrightarrow{ \sf{ \frac{4.5k}{4.5} = \frac{13.5}{4.5} }}$

Calculate

$\longrightarrow{ \sf{k = 3}}$

Hope I helped!

Best regards! :D

The coffee counter charges ?"$11.00" per pound for kenyan french roast coffee and ?"$13.00" per pound for sumatra coffee. How mu

zloy xaker [14]

Answer: The answer is 13 ponds of each type should be used.

Step-by-step explanation: Given that the coffee counter charges $11.00 per pound for kenyan french roast coffee and $13.00 per pound for sumatra coffee. We are to find the quantity of each type that should be used to make a 26 pound blend that sells for $12.00 per pound.

Let 'x' pound and 'y' pound of kenyan french roast coffee and sumatra coffee be used in the mixture of 26 pound.

So, we have

$x+y=26,~~~~~~~~~~~~~~~~~~~~~~(A)\\\\11x+13y=12\times 26.~~~~~~~~~~(B)$

Multiplying equation (A) by 11 and subtracting from equation (B), we have

$13y-11y=12\times26-11\times26\\\\\Rightarrow 2y=26\\\\\Rightarrow y=13,$

and from equation (A),

$x=26-13=13.$

Thus, 13 pounds of each type of coffee should be used.
