Answer:

-6.61

Step-by-step explanation:

Unless there is more included in this problem then -6.61 is the slope. Slope is represented as m in y=mx+b. Simply substituting in the slop and y-intercept shows that m=-6.61 or the slope is -6.61.

Jack crawled 4 ft and Christine crawled 3⁄4 the distance Jack crawled. If you add the distance they each crawled together, what
stepan [7]
Before going into the details of the problem, let us first write down the most important information required for solving this problem.
1 ft = 12 inches
The distance that was crawled by Jack = 4 ft
                                                                = (4 * 12) inches
                                                                = 48 inches
The distance crawled by Christine = 3/4 of the distance crawled by Jack
                                                         = (3/4) * 48 inches
                                                         = 3 * 12 inches
                                                         = 36 inches
Then
The total distance crawled by the two children's = (48 + 36) inches
                                                                             = 84 inches
So Jack and Christine together crawled a distance of 84 inches.

andrey2020 [161]

Let us assume capacity of large bottle = 1000 ml.

And capacity of each small bottle = 25 ml.

Reaming milliliters in large bottle = 250 milliliters.

Number of bottles = x bottles.

Total capacity of large bottle - capacity of a small bottle × number of bottles > Reamining milliliters in large bottle.

Therefore, we can setup an inequality.

1000 - 25 × x > 250.

1000 -25x >250.
