Answer:

x = 3/7  

Step-by-step explanation:

Step 1:

6 - 2x = 3 + 5x       Equation

Step 2:

6 = 3 + 7x        Add 2x on both sides

Step 3:

3 = 7x         Subtract 3 on both sides

Answer:

x = 3/7          Divide

Hope This Helps :)

Answer: The answer is x=3/7.

Step-by-step explanation:

So first you subtract on both sides by 5x and get -7x+6=3 then subtract 6 on both sides so you get -7x=-3 then lastly divide by -7 which is x=3/7. I hope this helps. The point of this problem is to isolate the x variable.

Complete Question

What is the area of the parallelogram?

Slant Height = 21 cm

Height = 15 cm

Base = 20 cm

Answer:

300cm²

Step-by-step explanation:

The formula for the area of the parallelogram = Base × Height

Base = 20cm

Height = 15cm

Area = Base × Height

= 20cm × 15cm

= 300 cm²

Therefore, the area of the parallelogram is 300 cm²

Christopher estimates it will take him half an hour to complete his math homework. He is able to complete it in 25 minutes. What
marin [14]

Answer:

The percent error in his estimate is<u> 16.67%</u>.

Step-by-step explanation:

Given:

Christopher estimates it will take him half an hour to complete his math homework.

He is able to complete it in 25 minutes.

Now, to find the percent error  in his estimate.

Time estimates of completing homework = 30 minutes.

Time actual taken to complete homework = 25 minutes.

Error in estimate = Time estimates of completing homework - Time actual taken to complete homework.

Error in estimate = 30 minutes - 25 minutes.

Error in estimate = 5 minutes.

Now, to get the percent error:

Percent\ error =\frac{Error\ in\ estimate}{Time\ estimates\ of\ completing\ homework} \times 100.

Percent\ error=\frac{5}{30} \times 100

Percent\ error=\frac{500}{30}

Percent\ error=16.67\%.

Therefore, the percent error in his estimate is 16.67%.

Y
alina1380 [7]

Answer:

the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2

Step-by-step explanation:

The computation of the coordinates of the point is shown below:

The angle is

= 4π ÷ 3

The radius is 1 unit

Now

x = rcos\theta, and y = rsin\theta

Now

x = 1cos(4π ÷ 3) = -1÷ 2

y = 1sin(4π ÷ 3) = -√3÷ 2

hence, the corordinates of the point of x and y is -1÷ 2 and -√3÷ 2
