According to graph, GMT time when the plane flew over the beacon was 9:24.
While looking closely at the graph on x axis , one will notice that each hour is divided into 5 parts and hence each part has 12 minutes. looking at y axis, one may find that each part on y axis resembles 20miles. Hence at 280 miles away from Bristol, The GMT time is 9:24.
<h3>What is a graph?</h3>
- In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.
- The relationships between two or more items are frequently represented by the points on a graph.
- The study of graphs, which are mathematical constructions used to represent pairwise relationships between things, is known as graph theory in mathematics. Vertices (also known as nodes or points) make up a graph in this sense, which are connected by edges (also called links or lines).
- Undirected graphs, in which edges connect two vertices symmetrically, are distinguished from directed graphs, in which edges connect two vertices asymmetrically. One of the main topics of study in discrete mathematics is graphs.

Answer:
- 30m +50 = 20m +100
- m = 5
- yes. symmetric property of equality.
Step-by-step explanation:
1. The expression for c in the first equation is (30m+50). Substituting that for c in the equation ...
c = 20m +100
gives you ...
30m +50 = 20m +100
__
2. Adding -50-20m to both sides gives ...
10m = 50
m = 5 . . . . . . . divide by 10
__
3. Doing the substitution in reverse, you would substitute (20m+100) for c in the equation ...
c = 30m +50
to get ...
20m +100 = 30m +50
This is the equation of part 1 with the expressions swapped to the other side of the equal sign. The symmetric property of equality tells you that changing sides of the equal sign does not change the value of the variable(s).
You get the same solution.
Answer:
x = 27/2
y = 7/2
Step-by-step explanation:
To solve for x:
We know that 7x + 30 and 11x - 24 are vertical angles. Therefore, they are congruent/equal to each other.
7x + 30 = 11x - 24
Isolate the variable & solve for x.
<u>x = 27/2</u>
To solve for y:
We know that 5y + 38 and 17y - 4 are vertical angles. Therefore, they are congruent/equal to each other.
5y + 38 = 17y - 4
Isolate the variable & solve for y.
<u>y = 7/2</u>
