First 6.60 divided by 6 to find the unit rate. It is 1.10 dollars per eraser. You then do 1.10 times 3 which will get you 3.30 dollars for 3 erasers.

Answer with Step-by-step explanation:

We are given that:

6 erasers cost $6.60.

We have to find:

The cost of 3 erasers

Cost of 6 erasers =$ 6.60

Cost of 6/2 erasers= $6.60/2

i.e. cost of 3 erasers= $3.30

Equation which determine the cost of 3 erasers is:

Cost of 6/2(=3) erasers= $6.60/2=$3.30

Use substitution to solve the linear system of equations

xenn [34]

we are given

system of equations

$y=4x$

$3x+5y=-46$

we can plug first equation into second equation

we get

$3x+5(4x)=-46$

Simplify left side

$3x+20x=-46$

$23x=-46$

Divide both sides by 23

and we get

$x=-2$

now, we can find y-value

$y=4*-2$

$y=-8$

so, our solution is

$(x,y)=(-2,-8)$ .............Answer
