How could I solve this equation, x+36=4x?

Try to put all the x-es on one side and then find a value of one x. In this case:

x + 36 = 4x / -x (both sides)
36 = 3x / :3 (both sides)
x = 12

Isolate 36 by subtracting x on both sides

36=4x-x
36=3x
divide both sides by 3
x=12

Two tapes, red and green, with lengths of 415 feet and 780 feet respectively are to be cut into pieces of equal length without r

ICE Princess25 [194]

Answer:

The greatest possible length of the pieces is 5 feet

Step-by-step explanation:

Red = 415 feet

Green = 780 feet

Find the greatest possible length of the pieces.

Find the Highest common factor

415 = 1, 5, 83, 415

780 = 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390 and 780

The Highest common factor of 415 and 780 is 5

The greatest possible length of the pieces is 5 feet

Red = 415/5

= 83 pieces

Green = 780/5

= 156 pieces

Multiply both sides by d.

dm=a+64d

Flip the equation.

a+64d=dm

Add -64d to both sides.

a=dm−64d

Answer:

<u>a=dm−64d</u>
