The diameter of the plate would be equal to the length of a side of the box.
Find the length of the box by dividing the perimeter by 4:
28 / 4 = 7 inches.
The diameter is 7 inches.
Circumference is found by multiplying the diameter by pi:
The exact circumference is 7PI
Using 3.14 for pi, the decimal answer is:
3.14 x 7 = 21.98 inches ( round answer as needed.)
x = -2
-2 + 2y = -12
add 2 to both sides: 2y = -10
divide by 2 on both sides: y = -5
when x = -2, y = -5
X * 5% = $100
x * .05 = $100
x * .05/.05 = $100/.05
x = $2000
Check
$2000 * 5% = $100
$100 = $100
Answer:
y = -3
Step-by-step explanation:
9x + 7y = -12
9(1) + 7y = -12
9 + 7y = -12
7y = -12 - 9
7y = -21 (divide both sides by 7)
y = -3
