Find square footage of his yard
assuming is is roughtly a rectangle
area of rectangle=length times width
length=20ft
width=12 ft
area=length times width=20 times 12= 240 square feet
how many packages?
1 pack times x is at least 240
1 pack times x>240
50 times x>240
divide both sides by 50
x>4.8
you can't buy 0.8 pack, so round up
5 packs needed
Your equation states y = 4(-1) + 3
Since the parentheses touch the number 4 which means you multiply, we will start with that first.
4 × -1 or 4(-1) (it means the same thing) would be -4
Now let us combine the equation.
y = -4 + 3
The addition property is included now,
-4 + 3 = -1
Therefore, your answer would be y = -1
Hope this helped! :D
I hope that this made sense to you.
number 4 is x = 9 and number 5 is x = 10
Answer:
(-3,-9)
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Given the equation 
, you need find the value of the variable x.
Then, you have to solve for x:
Add 
to both sides of the equation.
Divide by -8 to both sides of the equation.
Once you do this proccedure, you will get the value of the variable x.
Then:
