The equation to solve for p....[12p = 420]
Then divide both sides by 12.
And your answer....[p = 35]
Answer:
37°
Step-by-step explanation:
sum of exterior angles of a polygon is 360°
so, 41+(x+13)+(2x-14)+(3x-22)+(x-3)+38+(x+11)=360
8x+64=360, subtract 64 from both sides
8x=296
x=37°
Answer:
Step-by-step explanation:
if you're saying she ran .2 miles in 12 hours
then she ran .016 miles per hour
if you're saying she ran 2 miles in 12 hours,
then she ran 1/3 mile per hour or 0.3333 miles per hour
Answer:
Step-by-step explanation:
2c+12t=105, and 5c+3t=33, subtracting 4 times the second from the first gives you
2c+12t-20c-12t=105-132
-18c=-27 dividing each side by -18
c=1.5, making 2c+12t=105 become
2(1.5)+12t=105
12t=102
t=8.5
So each chair costs $1.50 and each table costs $8.50
