Highlighter pens cost $3. 86 per set at an office supply store. Which equation can be used to determine the price, P, of n sets

Leona [35]

Answer:

Total = ($3.86)n, but it ids not among the answer options.

Step-by-step explanation:

P would be equal to the price per pen set ($3.86) times the number of pen sets sold, n.

Total, P = ($3.86)n

I translated the paragraph into these options:

n = 3. 86P No, n = P/3.86

P = 3. 86/n No, P = 3.86n

n = 3. 86/P No, n = P/3,86

P = 3. 86n.

What is the value of y in the solution to the following system of linear equations?

Leviafan [203]

ANSWER

$y=12$

EXPLANATION

One way is to make x the subject in one equation and substitute into the other.

$2x+2=y$

$\Rightarrow 2x=y-2$

$\Rightarrow x=\frac{y}{2}-1--(1)$

The second equation is

$2y=5x-1--(2)$

Let us put equation 1 in 2

$\Rightarrow 2y=5(\frac{y}{2}-1)-1$

$\Rightarrow 2y=\frac{5y}{2}-5-1$

$\Rightarrow 2y=\frac{5y}{2}-6$

Multiplying through by 2 gives;

$\Rightarrow 4y=5y-12$

$\Rightarrow 4y-5y=-12$

$\Rightarrow -y=-12$

$\Rightarrow y=12$
