Im not sure about this one either -10=-14v+14v help

1 answer:

3 0

The above equation is invalid. It is not equal.

-10 = -14v + 14v

-14v + 14v = 0

-10 = 0 This is not equal. There is no solution. Thus, the equation is invalid.

Express each ratio as a unit rate.round to the bearest tenth,if necessary. 2 note books for $0.60

Option B

2 notebooks for $ 0.60 expressed as unit rate is $ 0.30 per notebook

<h3><u>Solution:</u></h3>

We have to express ratio as unit rate

Given that, 2 notebooks for $ 0.60

Number of notebooks = 2

Cost of 2 notebooks = $ 0.60

So we have to find cost of 1 notebook

$\begin{array}{l}{\text { cost of } 1 \text { notebook }=\frac{\text { cost of } 2 \text { notebook }}{2}} \\\\ {\text { cost of } 1 \text { notebook }=\frac{0.60}{2}=0.30}\end{array}$
