X= 23 degrees
To find this you first add up 124 and 33 which equals 157. Then you would subtract 157 from 180 because all triangles equal 180.

Find the value of the variables, giving brief reasons for your answer:

Pavlova-9 [17]

Answer:

a = 70°

b = 80°

Step-by-step explanation:

Angles on a straight line add up to 180°

⇒ a + 110 = 180

⇒ a = 180 - 110

⇒ a = 70°

The sum of the interior angles of a quadrilateral is 360°

⇒ a + b + 130 + 80 = 360

⇒ 70 + b + 130 + 80 = 360

⇒ b + 280 = 360

⇒ b = 360 - 280

⇒ b = 80°

The graph of an exponential function, f(x), is shown. Move numbers to the blanks to describe how f(x) increases and grows over d

yawa3891 [41]

By looking at the graph we can see that f(x) increase by 1 (on the vertical axis . or y-axis ) from 2 to 3, over the interval 0 to 1 ( horizontal axis, or x-axis)

It increases by 2 over the interval 1 to 2.

by 4 over the interval 2 to 3.

And by 8 over the interval 3 to 4.

Therefore this exponential function grows by a factor of 2 (since it doubles every by every interval of 1)

Mr and Mrs Smith buy tickets for hemselves and their four children.

Nookie1986 [14]

Answer:

Cost of an adult ticket is £10.75

Step-by-step explanation:

Given:-

Cost of 1 adult ticket is £6 more that the cost of a child ticket.

Total cost of 6 tickets = £40.50

c is cost of a child ticket and a is the cost of an adult ticket.

To find:- Cost of 1 adult ticket =?

Solution:-

For 2 adults and 4 children, and the total cost of tickets is £40.5, we get the following equation,

$2a+4c=40.5$ -----------------(1)

As the Cost of 1 adult ticket is £6 more than the cost of a child ticket, we can the following equation,

$a=c+6$ -----------------(2)

Now, substituting the value of a from equation 2 in equation 1 we get,

$2a+4c=40.5$

$2(c+6)+4c=40.5$

$2c+12+4c=40.5$

$6c=40.5-12$

$6c=28.5$

$c=\frac{28.5}{6}$

$c=4.75$ --------------------(3)

Now substituting the value of c from equation 3 in equation 2,

$a=c+6$

$a=4.75+6$

$a=10.75$

As a is the cost of 1 adult ticket,

Therefore Cost of an adult ticket is £10.75
