Answer:
38m
Step-by-step explanation:
the top side is equal to
2 + 5 + 1 = 8
the perimeter:
9 + 7 + 8 + 2 + 4 + 5 + 2 + 1 = 38
( x 1 + x 2 + x 3 + x 4 + x 5 ) / 5 = 89 Multiply both sides by 5
<span>x 1 + x 2 + x 3 + x 4 + x 5 = 89 * 5 = 445 </span>
<span>( x 1 + x 2 + x 3 + x 4 + x 5 + x 6 ) / 6 = 90 </span>
<span>( 445 + x 6 ) / 6 = 90 Multiply both sides by 6 </span>
<span>445 + x 6 = 6 * 90 = 540 </span>
<span>x 6 = 540 - 445 = 95</span>
11 is the answer, When you divide 32 by 4 you get 8 and then you add 3 to get 11.
-8 3/8 = -8 15/40
-12 4/5 = -12 32/40 ,because you had to get a common denominator.
Since you are subtracting from a negative the negative turns into a positive.
-8 15/40 + 12 32/40 = 4 17/40
