6 = 1/3 x + 5
Subtract 5
from each side: 1 = 1/3 x
Multiply each side
by 3 : 3 = x
Answer:
The table shows information about Town A in Illinois and Town B in Florida.If the two towns have the same population density Town B has a population of approximately 5,138.is right.
Given: Table shows Town A & Town B population.
To calculate the Population density, Divide the population by their size of the area.
We knows that according to the given that The Population Density of both the towns are equal.
Therefore, Town B has a population of 5,138 Option B is Correct.
hope this helps:)

Can you import the progress report picture please
Step-by-step explanation:
So we can solve it
Step-by-step explanation:
a) 2z+3z+4z=180
9z=180
z=20
So,three angles are 40,60 and 80
b) (y+30)+(2y+80)+(y+10)=180
y+30+2y+80+y+10=180
4y+120=180
4y=60
y=15
Three angles are 45,110,25
For question 6
Make x for first one subject of formulae
then it becomes
x=-2y
Substitution means replace your answer in the second part
since x=-2y
3(-2y) +4y = 4
-6y+4y=4
-2y=4
y= 4/-2
y=-2
Now to find x,replace the answer for y in one in the equation
so i replace y=-2 in the first part
x=-2y
x= -2(-2)
x=4
Therefore x=4 and y=-2
To check your answer replace x and y by the values you got and check if you get same answer.
