Answer:
For your area models you would draw two rectangles and divide one into 2 equal sections, and the other one with 8 equal sections. You then shade 1 box out of the first triangle with 2 equal sides. Then you would shade 7 boxes on the rectangle with 8 equal sides. These diagrams would show you that 7/8 and 1/2 are not equivalent.
To find out what fractions are equivalent to 1/2 you would take 1/2 and times the numerator and denominator by the same number.
1/2*2/2= 2/4
2/4=1/2
1/2*9/9= 9/18
9/18=1/2
2/4 and 9/18 both equal 1/2
Hope this helps ;)
Answer:
Their sum is 140. The measure of an exterior angle is supplementary to the respective interior angle.
Step-by-step explanation:
Since the angle are on a straight line, m2 and 140 sum to 180.
So m2=40. Because a triangle has 180 degrees, m1 and m3 must sum to 140.
The exterior angle is always on the same incline as the interior angle, so it is always supplementary to the interior angle.
Answer:
not all of them are proportional because they do not all equal the same.

PLEASE SEE ATTACHED IMAGE.
For this case the area is given by:
A = (22 + x) * (28 + x) = 722
Rewriting we have:
616 + 22x + 28x + x ^ 2 = 722
x ^ 2 + 50x + 616 - 722 = 0
x ^ 2 + 50x - 106 = 0
Solving the polynomial we have:
x1 = 2.04
x2 = -52.04
We take the positive root:
x = 2.04 inches:
Answer:
The width of the border to the nearest inch is:
x = 2inches
