Answer:

15

Step-by-step explanation:

Since, triangle ABC is the enlargement of triangle XYZ.

\therefore \triangle ABC \sim \triangle XYZ

So, corresponding sides of both the triangles would be in proportion.

\therefore \frac{x}{6}=\frac{25}{10}

\therefore x= \frac{6\times 25}{10}

\therefore x =\frac{150}{10}

\therefore x = 15

Jessica traveled to Portland by car. Going there took 3 hours, and the return trip lasted 6 hours. Jessica averaged a speed of 4
Nataly_w [17]

Answer:

The average speed of the trip there is <u>86 mph.</u>

Step-by-step explanation:

Given:

Time taken to reach Portland = 3 hours

Time taken to come beck from Portland = 6 hours

Average speed for the returning trip = 43 mph

Distance traveled for the returning trip can be obtained by multiplying the returning speed by returning time. Therefore, distance for returning trip is:

D=speed\times time=43\times 6=258\ miles

Now, distance traveled for the return trip is same as going to the trip.

So, distance traveled by Jessica going to Portland = 258 miles.

Time taken to go there = 3 hours

Therefore, speed of the trip there is given as the ratio of distance and time and is given as:

\textrm{Average speed}=\frac{Distance}{Time}\\\textrm{Average speed}=\frac{258}{3}=86\ mph

Therefore, the average speed of Jessica's car to go to Portland is 86 mph.

Can someone help fast please
Phoenix [80]

Answer:

\frac{3a}{a-2}

Step-by-step explanation:

\frac{2a - 7}{a}*\frac{3a^2}{2a^2 - 11a + 14}

Factorise 2a^2 - 11a + 14}

\frac{2a - 7}{a}*\frac{3a^2}{(2a - 7)(a - 2)}

2a - 7 cancels  2a - 7

\frac{1}{a}*\frac{3a^2}{(1))(a - 2)}

\frac{1(3a^2)}{a(a-2)}

\frac{a(3a)}{a(a-2)}

"a" cancels "a"

\frac{3a}{a-2}

Thus,

\frac{2a - 7}{a}*\frac{3a^2}{2a^2 - 11a + 14} = \frac{3a}{a-2}
