Answer:
4 feets = 48 inches
2 miles = 10,560 feets
1 2/3 yards = 5 feets
3 1/2 yards = 126 inches
Step-by-step explanation:
Recall :
1 Feet = 12 inches
1 MILE = 5280 feets
1 yard = 36 inches
1 yard = 3 feets
If 1 feet = 12 inches
4 feets will be ; (12 * 4) inches = 48 inches
If 1 mile = 5280 feets
2 miles will be ; (5280 * 2) = 10,560 feets
If 1 yard = 3 feets
1 2/3 yards will be ; (5 /3) * 3 = 5 feets
If 1 yard = 36 inches
3 1/2 yards will be ; (7 /2 ) * 36 = 126 inches
X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===
x = 30
Answer:
The answer is 1.65
Step-by-step explanation:
−2.25−(−3.9)
=−2.25−(−3.9)
=−2.25+3.9
=1.65
The answer is 5 because 10 divided by 2 is 5
80p=pr^2+p(2r)^2
80p=pr^2+4pr^2
80=r^2+4r^2
80=5r^2
16=r^2
r=4 for the smaller circle´s radius, and 8 is the larger circle´s radius.
Have a nice day, I hope this was helpful :D
