7+ 3x= -8
-8-7=-15
-15 divided by 3= -5
-5 is the answer
Answer:
x>5
Step-by-step explanation:
2x - 7 > 3
Add 7 to both sides
2x - 7 +7 > 3+7
2x > 10
Divide both sides by 2
2x/2 > 10/2
x > 5

Answer:
She needs to purchase 50 square feet of wood .
Step-by-step explanation:
we can find the number of square feet of wood needed to purchase by finding the area of the table
The area of the table = area of the triangle + area of the rectangle
Area of the triangle:
Area of the triangle = 
On substituting the values from the attached figure , we get
Area of the triangle = 
Area of the triangle = 
Area of the triangle = 10 square feet
Area of the rectangle:
Area of the rectangle = Length X Breadth
On substituting the values from the attached figure , we get
Area of the triangle = 
Area of the triangle = 40 square feet
Thus the area of the table = 10 + 40 = 50 square feet
