Answer:

50 mph and 60 mph

Step-by-step explanation:

Represent the two speeds by s and f (slower and faster).  Then f = s + 10.

We find the distance traveled by each car separately, sum up the absolute values of these distances and set this sum equal to 660:

(s + s + 10)(6 hr) = 660 mi.  Simplifying this, we get:

2s + 10 = 110, or

2s = 100.

Then s = 50 mph and f = (50 + 10) mph, or 50 and 60 mph (matches the last possible answer)

What is the distance between the points (-12, 11) and (-18, 17), to the<br> nearest tenth? *
Basile [38]

Answer:

8.5 units

Step-by-step explanation:

The distance between two points is given by

d=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}

Taking points (-12, 11) and (-18, 17) as the first and second points respectively then

d=\sqrt{(-18--12)^{2}+(17-11)^{2}}

d=\sqrt {36+36}

d=8.48528137423857 units

Rounded off to nearest tenths

d=8.5 units

mario collected 3g seashells. jasmine collected 10 more seashells that mario. write the number of seashells they collected toget
Rufina [12.5K]

Answer:

Total seashells = (6g + 10) seashells.

Step-by-step explanation:

Given that Mario collected 3g seashells.

Given that Jasmine collected 10 more seashells that mario. It means she collected (3g+10) seashells.

It says to write the number of seashells they collected together in terms of g.

Total seashells = Mario's seashells + Jasmine's seashells.

Total seashells = 3g + (3g+10).

Total seashells = 6g + 10.

Hence, Total seashells = (6g + 10) seashells.
