its just like subtracting when you add a negative number to a positive one. flip them around! makes it a lot easier.
Answer:
A. x<7
Step-by-step explanation:
The point at x=7 is an open circle, so the sign is <, not ≤
Answer:
7 1/7
Step-by-step explanation:
For the problem:
5
/7
× 10 = ?
Convert any mixed numbers to fractions:
10 = 10
Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
5 × 10
7 × 1
=
50
/7
50 ÷ 7 = 7R1, therefore:
50
/7
= 7 1/7
The result is:
5
7
× 10 = 7 1/7
Answer:
Step-by-step explanation:
Given
Perpendicular to 
Required
Determine the line equation
An equation has the form
Where
By comparison with
Because the line is perpendicular to , the following relationship exists
i.e. the condition for perpendicularity
Where m1 is the slope of the equation that passes through
So, we have:
The line equation is then calculated using:
Where
So, we have:
Add 11 to both sides

Answer:
x = 65
Step-by-step explanation:
The sum of exterior angles of a polygon is 360°.
40 + x + 77 + 2x + 45 = 360
3x + 165 = 360 . . . . simplify
x + 55 = 120 . . . . . . divide by 3
x = 65 . . . . . . . . . . . subtract 55
