Answer:

x = 10

Step-by-step explanation:

Here, we are tasked with calculating the value of x.

To do this, we need the picture of the wordings given in the question.

please check the attachment for a pictorial representation.

Now the theorem to use is that , the exterior angle of a triangle is equals the sum of the two opposite interior angle.

Thus, mathematically;

3x + 11 + 3x + 15 = 10x -14

6x + 26 = 10x -14

10x-6x = 26 + 14

4x = 40

x = 40/4

x = 10

Alina [70]

If there is 2 field trips with 23 students and each student costs $5 dollars. So for the 1st trip it will be 23x$5

1st trip- $115

And on the second trip its the same because there is 23 students that cost 5 dollars so it will be 23x5

2nd trip- $115

To find out the total of both trips youd add 115+115/

In total, for both trips it will cost $230 dollars.

As  given Chole and Tinos age , the present age of Tino is equal to 15 years.

As given,

Let x and y be the present age of Chole and Tino. respectively.

Combined age = 48

Given condition,

x + y = 48 _______(1)

Three years ago

x - 3 = 2y

⇒x =2y +3 _______(2)

Substitute the value of x in (1),

2y+3 +y =48

Katyanochek1 [597]

Answer:

-  \frac{3}{2}

Step-by-step explanation:

\boxed{gradient =  \frac{y1 - y2}{x1 - x2} }

Using the formula above,

slope of line

=  \frac{1 - ( - 14)}{ - 3 - 7}  \\  =  \frac{1 + 14}{ - 10}  \\  =  \frac{15}{ - 10}  \\  =  -  \frac{3}{2}
