Answer: 180 is the sum of the tringles
Step-by-step explanation:
2x+7x+11x=180
20x=180
x=9
Now you should put the the value of x to get the angles
2x=2x9=18
7x=7x9=63
11x=11x9=99
Now to double check add all of them together
99+18+63=180
Hoped I helped!
Answer:
C and H
Explanation:
All others are not the same shape, they tend to be pointing in different directions.
Let m and j be the current ages of Matthew and Jenny, respectively.
Now, Matthew is 3 times as old as Jenny, so the variables are in the following relation:
In 7 years, both of them will be 7 years older, i.e. their ages will be m+7 and j+7, and Matthew will be twice as old:
Now, remembering that m=3j, we can rewrite the second equation as
So, Jenny is 7 and Matthew is 21 (he's 3 times older).
In fact, in 7 years, they will be 14 and 28, and Matthew will be twice as old.
Answer:
d I think but dont quote me
Step-by-step explanation:
idk I just guessed
A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;
x = 1, y = 5.0125
B) The possible solutions of the given equation will be; x = 3.11 or -3.11
C) The solution to p(x) = g(x) is; x = 0 and y = 0
<h3>How to find the solution to simultaneous equations graphically?</h3>
When we are trying to solve two simultaneous equations, there are three methods we can use namely;
1) Elimination Method
2) Substitution Method
3) Graphical Method
Now, we see that we are to use the graphical method from the given graph.
Now, the solution to the given pair of equation will be the coordinates of the points where both graphs intersect.
A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;
x = 1, y = 5.0125
B) The possible solutions of the given equation will be the point where f(x) = 0 which is where the line crosses the x-axis and so we have;
x = 3.11 or -3.11
C) The solution to p(x) = g(x) is the coordinate;
x = 0 and y = 0
