Answer:
7
Step-by-step explanation:
First expand 2/3 (9x-6) = 4 (x+2)+ 2 By doing 2/3 (9x - 6)/3
Which gives you 2/3 (9x - 6)
Then you factor it 2/3 (9x - 6) 6 (3x - 2) get 6 (3x - 2) / 3
then you divide 6/3 with 2
Getting 2 (3x - 2)
The use the distributive law
2 x 3x - 2 x 2
simplify the equation
6x - 4
expand 4 (x +2) + 2: 4x + 10
which then equals 6x-4=4x+10
add 4 to both sides
6x-4+4=4x+10+4
simplify
6x=4x+14
subtract 4x from both sides
simplify again
2x=14
divide both sides by 2
2x/2 = 14/2
simplify one last time and get the answer
x=7
Answer:
543.4 liters
Step-by-step explanation:
The conversion 1 gallon is 3.8 liters can be used as the rate.
To convert gallons into liters, multiply the numbers of gallons by the rate, 3.8.
143 gallons X 3.8 = 543.4 liters
Therefore 143 gallons is 543.4 liters.
Answer:
-4
Step-by-step explanation:
y = -4x + 6 is the equation and -4 is the slope
Answer:
l = 9/2 or 4.5
m = 11/4 or 2.75
Step-by-step explanation:
4l + 8m = 40
8m = 40 - 4I
m = 5 - 0.5l
5l + 2m = 28
5l + 2(5 - 0.5l) = 28
5l + (10 - l) = 28
4l + 10 = 28
4l = 18
l = 18/4 or 9/2
l = 4.5
4l + 8m = 40
4(4.5) + 8m = 40
18 + 8m = 40
8m + 18 = 40
8m = 22
m = 22/8
m = 2.75
5x+4y=16 y=3/5x-3
y=mx+b <------ slope-intercept form
5x+4y=16
-5x -5x
============
4y=-5x+16
--------------
4
============
y= -5/4+4
Slope is -5/4
y-intercept is 4
y=3/5x-3
slope is 3/5
y intercept is -3
I can't do the graph but I'm sure you can figure it out!
Hope I helped.
