Step-by-step explanation:
for a mid point of (-3,-5) and(5,3) is.
(X1,Y1)= (-3,-5)
(X2,Y2)=(5,3)
now,
midpoint=(x1+x2)/2, ,(y1+y2)/2
=(-3+5)/2, (-5+3)/2
=2/2, (-2)/2
=( 1, -1)
:- midpoint=(1,-1)
$1.26 per yard. See photo for explanation.
Unfold it and add 4.
-3 < x-4 < 3
1 < x < 7
Answer:
A. 44°
Step-by-step explanation:
180° (straight line) - 88°
= 92
180° - 92°
= 88°
2y = 88°
y = 44°
Answer: 29.3
Step-by-step explanation:
Abby's average after taking 31 quizzes is 76.
Total test scores= 31 × 76 = 2356
After Abby's teacher drops her 3 lowest test scores, her average increases to 81. This means that (31-3)= 28 test scores were used.
Total scores = 28 × 81 = 2268
Sum of Abby's three lowest score
= 2356 - 2268
= 88
Average of the three scores will now be 88 divided by 3
= 88/3
= 29.3
The average is 29.3
