Answer:
(A)74
Explanation:
Let her average score on the last two tests = x.
The six scores will now be: 82,78,87,73, x and x.
Since the average score for her first six chemistry tests = 78
We then solve for x.
Her average score for the last two tests is 74.
Answer:
Step-by-step explanation:
in an isocelles trapezoid, we have the properties:
the lower base angles are congruent
the upper base angles are congruent
we have an angle= 44
the angle #3= 44 because of the properties
so the lower base angles are equal and equal to 44
sum of the angles in trapezoid=360
360-(44*2)=360-88=272
upper base angles are equal
272/2=136
angle1=angle2=136
Answer:
r = -3.2
Step-by-step explanation:
-0.6(r+0.2) = 1.8
Divide by -.6
-0.6/-.6(r+0.2) = 1.8/-.6
r+.2 = -3
Subtract .2 from each side
r+.2-.2 = -3-.2
r = -3.2
The even integer between them is their average value, -88/2 = -44.
Your two integers are -45 and -43.
