Answer: 6+4x=26, 4x=20
Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.
If you solve the equation, 2x+3=13 (subtract 3 from both sides)
2x=10 (divide both sides by 2)
x equals 5.
if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.
Most important rule of Pre- algebra and algebra, do the opposite operation.
So what you do is subtract 3/8 to isolate the variable. 1/2 = 4/8 so just do 4/8-3/8 and get 1/8 so m = 1/8
Answer:
nope
Step-by-step explanation:
Answer: Assume the cross section is taken at the same height where the circumference was measured. Then
48/3 = 16 inches, close enough, actually. Trees aren't cylinders.
48 × 7 / 22 inches = 15.2727272
48/3.1415926 = 15.2788747
48/pi = 15.2788745368219522338128412837... ☺️
Step-by-step explanation:
circumference / diameter = pi = 3.1415926......
So diameter = circumference / pi.
Answer:
22/15 which would also be 1 7/15
