Answer:
Step-by-step explanation:
Given inequality:
We need to solve the given inequality for solutions of 
.
In order to solve for the inequality, we will isolate in one side of the in-equation.
We have,
Subtracting both sides by 7.
Thus, the solution of the given inequality is all real numbers greater than 4.
The solution in interval form can be written as (4,∞).
The graph for the inequality is shown below.
Answer:
Set opposite side with same term equal
Step-by-step explanation:
x = 6 , so y = 8
Answer to A and B.
The area of rectangle: 22.8×14.5=330.6 ft²The area of rectangle: 22.8×14.5=330.6 ft²
The area of triangle: 12⋅12⋅22.8=136.8 ft²The area of triangle: 12·12·22.8=136.8 ft²
The total area of figure: 330.6+136.8=467.4 ft²The total area of figure: 330.6+136.8=467.4 ft²
B: In order to find how many gallons of paint are needed, we need to divide the total area that needs to be painted (467.4 square ft) by the area one gallon covers (350 square ft)
467.4 ÷ 350 ≈ 1.34 gallons
Since only whole gallons of paint can be purchased, you will need 2 gallons of paint.
At $20 each, the cost will be 2 x $20 or $40.
