Answer:
Area of a triangle formula is 1/2 x base x height
Area of the garden = 1/2 x 25 x 10 = 125 square feet.
1 bag covers 10 square feet, divide total area by 10"
125 / 10 = 12.5
She will need to buy 13 bags.
Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.
Answer:
b
Step-by-step explanation:
Answer: The correct option is, (B) Addition property
Step-by-step explanation:
- Addition property : In this property, whatever is added to one side of the equal sign must be added to the other side.
For example : If x = y then x + z = y + z
- Multiplication property : In this property, whatever is multiplied to one side of the equal sign must be multiplied to the other side.
For example : If x = y then x × z = y × z
- Transitive property : If one value (x) is equal to the another value (y), which is equal to the another value (z), then the first value (x) is equal to the third value (z).
For example : If x = y and y = z then x = z
The given inequality expression is,
5x - 9 < 91
5x -9 + 9 < 91 + 9
(Using Addition property because we are adding 9 on both the side)
5x < 100
5x ÷ 5 < 100 ÷ 5
(Using Division property because we are dividing by 5 on both the side)
x < 20
Therefore, addition property is used in the second step of solving the inequality.
