Answer:
17.5liters per week and 525liters per month
Answer:
x=15
Step-by-step explanation:
you multiply each given number then simplify
You first substract 18 from both sides so you get
10x<-20 you then divide by 10 so the answer is
x<-2
Answer:

Step-by-step explanation:
Notice that the answers they give you to choose from are all lines in slope y-intercept form, it would be very simple to just find the answer finding yourself the slope and y-intercept of the line in question.
Since they give you two points
and
for the line, use them to find the slope of the line that goes through them, with the formula: 
Therefore, the slope of the line must be 
Now, find the y-intercept (b) using the general form of a line with the given slope:

Use one of the given coordinate points to request that the line passes through it. For example, through the point (-3,6) (when x = -3, y must be 6):

then the y-intercept must be 5. Therefore our line is :
which appears listed as your second choice.
Answer:
c=+20
Step-by-step explanation:
6c+14=-50+4+9c
move all terms to the left
6c+14-(-50+4+9c)=0
add all the numbers and variables together
6c-(9c-46)+14=0
We get rid of parentheses
6c-9c+46+14=0
add all the numbers and variables together
-3c+60=0
move all terms containing c to the left, all other terms to the right
-3c=-60
c=-60/-3
c=+20
Hope this helps!!!
