If there are 12 items adding up to 60%, we want to know how many items more it will take to equal 100% So set up this equation 12/x = .6 then solve for x. x=12/.6 x = 20 now that we know the total you can subtract 12 from 20 and get 8, that is the number of items left on the list.
Ok let’s say he folds N=14 so F would be the other q4
A= +11 It’s the second one
Answer: i only know question one so here
The first mathematical error occurred going from line __3__ to line _4___.
Why it is incorrect:
It is incorrect because the minus sign was not properly distributed. Line 4 should be ...
5 -2x +6 ≤ 4x -8
a.
The second mathematical error occurred going from line ___5_ to line 6____.
Why it is incorrect:
It is incorrect because 1 was added on the left and subtracted on the right. The same number needs to be added or subtracted on both sides.
b. Solve the inequality correctly.
5 -2x +6 ≤ 4x -8---------------correct line 4
11 -2x ≤ 4x -8------------ combine constants
19 -2x ≤ 4x ------------add 8
19 ≤ 6x--------------- add 2x
19/6 ≤ x----------- divide by 6
