Answer:
81
Explanation:
Morgan's family bought 6 cartons of eggs, each having 12 eggs in them. So, 6*12=72
Then, you would add 9 the answer you just got: 72+9=81
Making 81
The perimeter is the sum of all four sides so it would be 2+2+5+5=14
<u>Given</u>:
Two parallel lines are cut by a transversal and form a pair of alternate interior angles.
One angle measures (6x + 5)° and the other measure (7x - 4)°
We need to determine the measure of each angle.
<u>Value of x:</u>
Since, the two angles are alternate interior angles, then the two angles are congruent.
Thus, we have;




Thus, the value of x is 9.
<u>Measure of each angle:</u>
The measure of each angle can be determined by substituting
in the measures of each angle.
Thus, we have;


Thus, the measure of each angle is 59°

Explanation:
Make use of the properties of equality.
a = 2b +6 . . . . . given
a = 9b -8 . . . . . given
2b +6 = 9b -8 . . . . . . . substitution property of equality
6 = 7b -8 . . . . . . . . . . . subtraction property of equality
14 = 7b . . . . . . . . . . . . . addition property of equality
2 = b . . . . . . . . . . . . . . . division property of equality
b = 2 . . . . . . . . . . . . . . symmetric property of equality
