13.5/3 = 4.5
He hiked for 4.5 hours.
Answer:
Here is the answer
Step-by-step explanation:
Apples in 1 baskets=100
Apples in 64 baskets=100*64-6400
apples (before adding 30 apples in each
basket).... ..(1)
Some apples left unpacked
So he added 30 apples to each
Total apples added by him- 30*64(in each basket*no of baskets)
= 1920 apples
.(2)
So total no apples eq(1)+eq(2)
= 6400 apples + 1920 apples
=8320 apples packed in total
Therefore the total no. of apples packed were 8320 apples.
Hope this helps
Thanks
C. Coordinates of D' (-6,3)
<u>Step-by-step explanation:</u>
When any figure is rotated 180° in the counterclockwise direction, then the coordinates of the vertices is changed into its opposite sign.
(x, y) → (-x, -y)
The coordinates of the vertices of quadrilateral ABCD is changed when it is rotated 180 degrees counterclockwise about the origin as,
A (7,-7) → A'(-7,7)
B (4,-10) → B' (-4,10)
C (1.5, -2.5) → C' (-1.5, 2.5)
D (6, -3) → D'(-6,3)
So the coordinates of D' will be (-6,3)

The best way for him to check his answer would be to simply plug in the value found for x into the equation.
4(2) - 6 = 2
8 - 6 = 2
2 = 2
