Answer:
(b) 64 sq. in.
Step-by-step explanation:
The shaded area is the difference between the overall area and the areas of the cutout corners.
The overall area is 10 in by 10 in, so is ...
A = s² = (10 in)² = 100 in²
The area of the cutout at each of the four corners is ...
A = s² = (3 in)² = 9 in²
So, the total area of the four cutouts is ...
cutout area = 4 × 9 in² = 36 in²
The remaining area is then ...
100 in² -36 in² = 64 in²
Answer: the system of equations are
3x + 2y = 170
4x + 6y = 360
Step-by-step explanation:
Let x represent the price of a child's ticket in dollars.
Let y represent the price of an adult's ticket in dollars.
The Brown family paid 170 for 3 children and 2 adults. This would be expressed as
3x + 2y = 170
The Peckham family paid 360 for 4 children and 6 adults. This would be expressed as
4x + 6y = 360

I'm not sure about the answer
3 × 2=6
6×1=6
So based on place values, the One's place is occupied by 4. To round to this digit, you go one number to the right. If that number is 5 or higher, you add one to 4. If it is less than 5, you don't add any to 4. Since 7 is greater than 5, you add 1 to 4, giving you 5, since you can now remove all the other numbers to the right.
5.
