Answer:

Use the distributive property to multiply 2 by x−1.

l2x-2I=11

2x-2=-11

Add 2 to both sides of the equation.

2x=-9

Divide both sides by 2.

x=13/2

That's the final answer

It takes me 20 minutes to do my math assignment for the day. I have been lazy and I spend 2 hours and 20 minutes doing my work l
Katena32 [7]

Answer:

Assignments finished = 7

Step-by-step explanation:

Given that:

Time taken for one assignment = 20 minutes

Time spent on working = 2 hours 20 minutes

2 hours = 120 minutes

Time spent on working = 120 + 20 = 140 minutes

Number of assignments = \frac{Total\ time\ spent}{Time\ on\ one\ assignment}

Number of assignments = \frac{140}{20}

Number of assignments = 7

Hence,

Assignments finished = 7

Sharon runs on a trail that is 17/2 miles long. She ran 1/3 of the trail and walked the rest of the way. How far did she run?
Natalka [10]

Answer:

17/6 miles or 2 5/6 miles

Step-by-step explanation:

The train is 17/2 miles

She ran 1/3 of the way

Multiply 1/3*17/2

1/3*17/2 = 17/6

We can change this to a mixed number

17/6 miles =2 5/6 miles

El recorrido de una etapa de una vuelta ciclística tiene una longitud de 213 kilometros y un ciclista recorre 2/3 del trayecto e
Maurinko [17]

the question in English

The route of a stage of a cycle tour is 213 km long and a cyclist covers 2/3 of the route in five hours.

a) How many kilometers are left to finish the stage?

b) If he continues with the same average speed, how much time does he have left to finish the stage?

Step 1

we know that

1) Total kilometers of a stage is 213\ km

2) The cyclist covers \frac{2}{3} of the route

so

the kilometers remaining to finish the stage is equal to

(1-\frac{2}{3})*213= \frac{1}{3}*213\\ \\=71\ km

therefore

<u>the answer   Part a) is </u>

71\ km

Step 2

<u>Find the average speed of the cyclist</u>

we know that

the speed is equal to

speed=\frac{distance}{time}

we have

time=5\ hours\\ distance=\frac{2}{3}*213=142\ km

substitute

speed=\frac{142}{5}=28.4\frac{km}{h}

Step 3

<u>Find the time remaining to finish the stage</u>

we know that

speed=\frac{distance}{time}

Solve for the time

time=\frac{distance}{speed}

we have

distance=71\ km\\ speed=28.4\frac{km}{h}

substitute

time=\frac{71}{28.4}=2.5\ hours

therefore

<u>the answer Part b) is</u>

2.5\ hours
