2.5x + 4x = 39
6.5x = 39
x = 39 / 6.5
x = 6
Answer:
A
Step-by-step explanation:
You have to divide both by common factor, in this case it's 12
So 72/60 = 6/5
Thus, 6/5 is the simplest form.
Answer:
The perimeter is 7 dm
Step-by-step explanation:
we know that
The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Let
c------> the length of the third side
case a)
1+c>3
c>2 dm
case b)
1+3> c
4 > c
rewrite
c<4 dm
The solution for c is the interval------> (2,4)
therefore
the value of c must be equal to
c=3 dm (because is an integer)
The perimeter is equal to
P=1+3+3=7 dm
Your answer is at the top good luck!
