Answer:
Substitution
Step-by-step explanation:
tbh i havent checked so sorry if its wrong
The value of x in terms of p is 15/p.
The value of x when p is -5 is -3.
Pls tell me if i’m wrong in any way!
We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7
where b represents the base.
Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a
We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm
First you have to make it multiplication so you flip 5/2 around and the two “2’s” will cancel each other so it will be 17/5 or 3 2/5
