Answer:
The correct answer is X - 40% of X = 0.6 X, where X is the amount of plastic the company used initially.
Step-by-step explanation:
A company uses X amount of plastic to make bags.
But now the company decreases this amount by 40%.
Decrease in amount of plastic used is 40 % of X = 0.4X.
Therefore the expression that represents the amount of plastic used after this decrease is X - 40 % of X = X - 0.4X = 0.6X.
Thus after the decrease the company now uses 0.6X amount of plastic which is 40% less than the initial.
Answer:
![w = - 9](https://tex.z-dn.net/?f=w%20%3D%20%20-%209)
Step-by-step explanation:
![- 2w = - w + 9](https://tex.z-dn.net/?f=%20-%202w%20%3D%20%20-%20w%20%2B%209)
Add w to both sides:
![- w = 9](https://tex.z-dn.net/?f=%20-%20w%20%3D%209)
Negate both sides:
![w = - 9](https://tex.z-dn.net/?f=w%20%3D%20%20-%209)
I’m fairly sure it’s 2N as N is the amount of people. Say there were 100 people that turned up, you would need 200 party favours (obviously because it’s two each) so 2N is 2 x 100 = 200
I’m sorry if it’s wrong! That’s what I would have put :)
Answer:
-12
Step-by-step explanation:
12(-1/4) - 3(3)
-3 -9
-12
2(4x-3) ≥ - 3(3x) + 5x
2* 4x - 2*3 ≥ - 9x + 5x
8 x - 6 ≥ -4x
8 x + 4 x ≥ 6
12 x ≥ 6
x = 6/12 divide 6/6 = 1 and 12 / 6 = 2
x = 1/2
hope this helps!
