Answer:
2/3
Step-by-step explanation:
To find the slope, we use the formula
m = ( y2-y1)/(x2-x1)
= ( -8 - -10)/( 15 -12)
= ( -8+10)/( 15-12)
= 2/3
Answer:
Solve for X ( The question I did was an example )
Step-by-step explanation:
To solve and equation like 2x+9=30 you will have to isolate the number with a variable. You need to subtract 9 on both sides for that to happen.
2x=21
Now the next step is to divide. You have to divide to get the answer.
x=21/2
x= 10.5
Answer:
The total cost of resurface the path is 
Step-by-step explanation:
step 1
Find the area of the path
The area of the path is equal to the area of the path plus the swimming pool minus the area of the swimming pool
step 2
Find the cost of resurface the path
Multiply the area of the path by $2 per square foot
Answer:
5x + 16
Step-by-step explanation:
the first thing you do in this equation is to distribute the 2 into x + 6
you get
2x + 12 + 3x + 4 = ?
then you must put the 2x and the 3x together
5x + 12 + 4
and you can then add the 12 and 4
5x + 16
