Kamila buys a notebook for $1.59 and pens for $0.29 each. She spends $5.07.

emmasim [6.3K]

Answer:

12 pens

Step-by-step explanation:

Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.

Price of a notebook = $1.59

Price a pen = $0.29

Total amount spent = $5.07

But,

1.59 + 0.29 n = 5.07

So that,

0.29 n = 5.07 - 1.59

0.29 n = 3.48

n = $\frac{3.48}{0.29}$

= 12

Therefore, Kamila bought 12 pens.

PLEASE HELP ME WHAT AM I SUPPOSE TO DO?!

stepladder [879]

Answer:

Step-by-step explanation:

Angle 2= 50

angle 1= 180-50= 130 degrees (linear pair (sum 180))

angle 3= 130 degrees (vertically oposite angles are equal)

angle 6= 130 degrees (alternate interior angles)

angle 5= 180-130= 50 degrees (linear pair)

i hope this helps :)

Answer:

(6, -4)

Step-by-step explanation:

To solve a linear system of equations graphically, graph the given equations and locate where the two lines intersect. The point of intersection is the solution to a system of linear equations.

Given linear system of equations:

$\begin{cases}y=-x+2\\x-3y=18\end{cases}$

Rewrite the second equation to make y the subject:

$\implies x-3y=18$

$\implies x-18=3y$

$\implies y=\dfrac{1}{3}x-6$

To graph a linear equation, find two points on the line by substituting two values of x into the equation. Plot the points and draw a straight line through them.

Equation 1

$x=0 \implies y=-(0)+2=2 \implies (0, 2)$
