This question is a little tricky. Carla had a bill of $15, which we will add to the cost of Rob's lunch. They left a 20% tip on the TOTAL cost of both their lunches, which should equal $6. 20% is equivalent to 0.2. So, the equation is 6=0.2(x+15). In other words, 20% of the sum of Carla and Rob's lunches is 6 dollars.
Answer: 6=0.2(x+15)

<h3><u>Distance travelled each day is</u> : </h3>
<h3><u>Explanation</u> : </h3>
Distance travelled in 14 days is : 456.4 km
And if he travels same Distance each day, so let the Distance travelled on each day be x
According to question ~



So, he travels 32.6 km per day
<span>[ (1 / 36) - (1 / x²) ] / [ (1 / 6) + (1 / x) ]
[ (x² - 36) / 36x² ] / [ (x + 6) / 6x ]
</span>remember that<span>:
x² - 36 = (x + 6)(x - 6)
so
[ (x+6)(x-6) / 36x² ] / [ (x + 6) / 6x ]
[ (x+6)(x-6) / 36x² ] * [ 6x / (x + 6) ]
6x / 36x² = 1 / 6x
[ (x+6)(x-6) / 6x ] * [ 1 / (x+6) ] -------------------- > </span>(x - 6) / 6x<span>
The answer is </span>(x - 6) / 6x<span>

Answer: The slope is 5
Step-by-step explanation:
You can calculate the slope of the line with this fomula:

Given the points (2,3) and (1,-2), you can identify that:

Now, the final step is to substitute these values into the formula
, getting that the slope of this line is:


I Think The Answer Is -20 Or 66...Because When I Wrote It Out On Paper I Tried To Solve For Me & I Came Up With 66 But When I Wrote It Out Once More I Came Up With -20..Hope I Helped.
