Answers
Answer: The amount of is changed by $38.
Explanation:
It is given that Mrs. Armour bought 7 pairs of socks for $3 each, and a sweater for her dog for $12.
The cost of 1 pair of socks is 3. So the cost of 7 is,
The cost of 7 socks is $21.
She purchase 1 sweater for $12.
Total amount she spent is,
It means after purchasing the socks and sweater the total amount is reduced by $33.
It is given that she found a $5 bill on sidewalk. It means the total amount is increased by $5. Hence the total change in the amount is,
Therefore, the amount of Mrs. Armour had is reduced by $28.

Brain is 173/30 feet away from where he started.
Step-by-step explanation:
0 + 31/5 = 31/5 feet
31/5 - 4/3 = 73/15 feet
73/15 + 9/10 = 173/30 feet
Answer:
Step-by-step explanation:
31/5 - 4/3 + 9/10 =
186/30 - 40/30 + 27/30 =
213/30 - 40/30 =

the coordinates of its image?
Answers
The coordinates of the image of point (2 , -4) after reflection across
the x-axis is (2 , 4)
Step-by-step explanation:
Let us revise the reflection of a point
1. If point (x , y) reflected across the x-axis, then its image is (x , -y)
2. If point (x , y) reflected across the y-axis, then its image is (-x , y)
3. If point (x , y) reflected across the line y = x, then its image is (y , x)
4. If point (x , y) reflected across the line y = -x, then its image is (-y , -x)
∵ Point (2, -4) is reflected across the x-axis
∵ Point (x , y) reflected across the x-axis, then its image is (x , -y)
- Chang the sign of the y-coordinate of the point to find its image
∵ The y-coordinate of the point is -4
∴ The y-coordinate of the image is 4
∴ The image of the point (2 , -4) is (2 , 4) after reflection across the
x-axis
The coordinates of the image of point (2 , -4) after reflection across
the x-axis is (2 , 4)
