6 erasers cost $6.60. Which equation would help determine the cost of 3 erasers?

2 answers:

6 0

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

Answer:

x=45

Step-by-step explanation:

2x-56=34

Add 56 to both sides

2x-56+56=34+56

Simplify;

2x=90

Divide both sides by 2

2x/2=90/2

Simplify;

x=45

What values of k will make the line containing points (k,3) and (-2,1) parallel to the line through (5, K) and (1,0)

rjkz [21]

Answer:

k = -4 or 2

Step-by-step explanation:

For the lines to be parallel, the lines would need to be the same slope. This means to find the slope of each we would take the difference of the rise over the run.

$\frac{1-3}{-2-k}=\frac{-2}{-2-k}$

and

$\frac{0-k}{1-5}=\frac{-k}{-4}$

To find K, set them equal.

$\frac{-2}{-2-k} = \frac{-k}{-4}\\-k(-2-k) = -2*-4\\2k+k^2=8\\k^2+2k-8=0$

Factor the quadratic and solve for K.

$(k+4)(k-2)=0$

k+4=0 so k=-4

k-2=0 so k=2
