Answer:
-(4x + 7)/2 - (3x - 2)/2 = (-4x - 7 - 3x + 2)/2 = (-7x - 5)/2
(2x 6)(x-1)=0 happy to help :)
They are 2015 and 2016.
divide 4031 by 2, and get rid of the decimal:
You will get 2015.
2015+2015 = 4030
2015+2016=4031
Answer:
12 days
Step-by-step explanation:
Total gallons of the family's drinking water needs = gallons consumed by children + gallons consumed by adults
3
+ 1
=
Converting to decimals
3.5 + 1.75 = 5.25 = 5
If there are 63 gallons, the water supply would last for :
63 / 5.25 =12 days
I think you can find it graphically by points through a table you create like:
let x = 0, and find the value of y
for example for the first equation when we let x = 0 you find y = 6 and be in the form of (0,6) then draw them or you can let x = -2 or -3 , etc as you like
to be more accurate you can find 3 pionts and start graphing them
these two equations are straight lines and they will intersect in a point
