Answer:
540
Step-by-step explanation:
(n-2)×180
(5-2)×180
3×180
540
y=47.38+.617x
130 = 47.38+.617x
subtract 47.38 from each side
82.62=.617x
divide by .617 on each side
133.906 =x
to the nearest minute x=134
Answer Choice C
Answer:
a. 90°
b. 180°
c. 180°
Step-by-step explanation:
For these problems there is a bit of a shortcut you can take. Each figure is entirely within one quadrant, and the rotation is said to be by 90° (one quadrant), 180° (two quadrants), or 270° (three quadrants) clockwise.
a. The image is in the adjacent clockwise quadrant, so rotation is 90°.
b, c. The image is in the diagonally opposite quadrant, so rotation is 180°.
Answer:
length= 7in
width= 2in
Step-by-step explanation:
7*2=14 which is the area
7-2= 5 which is the difference of inches between the length and width
Answer: 
Step-by-step explanation:
You can use the Method of substitution.
Substitute the equation 
into the equation 
and then you must solve for the variable x:
Apply Distributive property:
Subtract 12 from both sides of the equation and then add the like terms. Then you get:
