-np - 80 < 60....add 80 to both sides
-np < 80 + 60
-np < 140...divide both sides by p
-n < 140/p ...now multiply by -1 to make n positive, and change inequality sign
n > -140/p
Answer:
The solution of the system is x=-1, y=-2
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both lines
using a graphing tool
The intersection point is (-1,-2)
see the attached figure
therefore
The solution of the system is x=-1, y=-2
Answer:
6 2/3.. i think
Step-by-step explanation:
hopefully u understand my messy handwriting
Step-by-step explanation:
3/8x-1/3x+6=x
(3(3x)-1(8x))/24=x-6
(9x-8x)=24(x-6)
x=24x-24×6
x=24x-144
144=24x-x
23x=144
x=144/23
Answer:
450
Step-by-step explanation:
If 81 is 18% of a number then we can say that:
x × 0.18 = 81
We multiply by 0.18 because 18% is 0.18 as a decimal. So to work out the real number we divide 81 by 0.18:
81 ÷ 0.18 = 450
