24 pine trees in equal rows, with the number of trees in each row being 10 or more than the number of rows.
Hugo could have planted 12 trees in 2 rows.
<u>Statement</u><u>:</u>
The circle has a diameter of 16 inches.
<u>To </u><u>find </u><u>out:</u>
The area of the circle.
<u>Solution</u><u>:</u>
- Diameter of the circle = 16 inches.
- Radius of the circle
- = Diameter ÷ 2
- = 16 inches ÷ 2
- = 8 inches
- We know, area of a circle = πr² where r is the radius.
- Therefore, the area of the circle
- = 3.14 × (8)² square inches
- = 3.14 × 64 square inches
- = 200.96 square inches
- = 201 square inches [rounded to the nearest square inch]
<u>Answer</u><u>:</u>
C) 201 square inches

Minus 3y both sides
2y-6=-20
add 6 to both sids
2y=-14
divide 2
y=-7
Answer:
Step-by-step explanation:
Let x represent the number of stamps from Europe.
Let y represent the number of stamps from Africa.
Let z represent the number of stamps from Asia.
She has 47 stamps in all. This means that
x + y + z = 47 - - - - - - - - - - - 1
The number of African stamps is 2 times the number of Asian stamps. This means that
y = 2z
She has 20 stamps from Europe. Therefore, substituting x = 20 and y = 2z into equation 1, it becomes
20 + 2z + z = 47
3z = 47 - 20 = 27
z = 27/3 = 9
y = 2z = 2 × 9
y = 18
She has 20 stamps from Europe, 18 stamps from Africa and 9 stamps Asia.
2.5x-8=5x+12
