Answer:
28-4x
Step-by-step explanation:
Step 1: Open most inner bracket and simplify
=18-2(x+x-5)
=18-2(2x-5)
Step 2: Expand brackets by multiplying 2 in and simplify
=18-2(2x)-2(-5)
=18-4x+10
=28-4x
Therefore the answer is 28-4x
Answer:
30.4
Step-by-step explanation:
if you want the basic perimeter just add up all the sides
5x-6y=10
-5x -5x
-6y=-5x + 10
y-yV1=m(x-xV1)
y+1 = -5 (x+6)
destribute the -5 to the parinthease.
y+1 = -5x - 30
-1 - 1
y= -5x -31
Answer:
No, they aren't proportional.
Step-by-step explanation:
To simplify a ratio, you have to find the common greatest factors between both variables on each side. In this case, 25:16 is the simplist form and could never be minimized to 5:4.
