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)

Section 1:

using this format we can determine what the answer is:

42 105
—— • ——-
100 x

(the spacing may be off but imagine two separate fractions)

first multiply 100 by 105 to get 10,500

then divide by 42 to get 250

this means that sasha’s book has 250 pages

section b:

using the same formula we can solve this problem:

first we need to multiply 250 by 2 to get the total cost of both tickets

175 x
—— • ——
100 500

(again spacing may be off but think of two separate fractions)

then multiply 500 by 175 to get 87,500

then divide by 100 to get 875

to find the profit subtract 875-500

this means he will make $375 profit

conclusion:

sasha’s book has 250 pages

trevor will make $375 profit

this is the method my teacher taught me last year so it should be right, hope this helps and please mark brainliest!!

The owner of a deli gathered data about the number of flavored bagels and plain bagels sold during the first hour of business fo
pychu [463]

Answer:

Approximately 25 flavored bagels.

Step-by-step explanation:

The scatter plot is a graph on cartesian plane where;

y-axis represents the number of plain bagels sold.

x-axis representing the number of flavored bagels sold.

The equation of the straight line on the graph is;

y = 1.731x + 6.697

The graph formed is as attached below.

The slope of the graph means that for every 1 flavored bagel sold, 1.731 plain bagels are sold within one hour.

When y = 50 ;

50 = 1.731x + 6.697

x = \frac{50 - 6.697}{1.731} = 25.01617562 ≈ 25 flavored bagels.
