Answer:
23
Step-by-step explanation:
The sides opposite equal angles of a triangle have equal length:
KJ = IJ
9x -11 = 6x -5
3x = 6 . . . . . . . . add 11-6x
x = 2
__
Perimeter = (7x-5) +(6x -5) +(9x -11) = 22x -21 = 22(2) -21 = 23
The perimeter of triangle JIK is 23 units.
This is a goofy question, because the method of counting is not very well defined.
23 + 5x + 7y - x - 5 - 27
Let's make everything an addition because addition is associative but subtraction isn't.
= 23 + 5x + 7y + -x + -5 + -27
OK, let's commute a few things
= 5x + 7y + -x + -5 + -27 + 23
= 5x + -x + 7y + -5 + -27 + 23
That's two commutations.
= (5x + -x) + 7y + ((-5 + -27) + 23)
I'll count that as three associations
= (5 + -1)x + 7y + -9
That's a distributive law (in reverse which is fine)
= 4x + 7y - 9
Tallying that's associative law 3 times, commutative law 2 times, distributive law 1 time.
Answer:
point M represent s a third
6.6× 0.05= 0.33=1/3
Answer:
47x - 9
Step-by-step explanation:
-4(4x + 4) + 7(1 + 9x)
-16x -16 + 7 + 63x
47x -9
You can find what x = because there is no = sign. This is in simplest form.
Large boxes are 40 pounds.
Small boxes are 30 pounds.
