Answer:
x=10
Step-by-step explanation:
Let's solve your equation step-by-step.
40−x=3x
Step 1: Simplify both sides of the equation.
40−x=3x
40+−x=3x
−x+40=3x
Step 2: Subtract 3x from both sides.
−x+40−3x=3x−3x
−4x+40=0
Step 3: Subtract 40 from both sides.
−4x+40−40=0−40
−4x=−40
Step 4: Divide both sides by -4.
−4x
−4
=
−40

x=10
5/16 = 25/80
3/8 = 30/80
2/5 = 32/80
Because 25/80<30/80<32/80, the washer with the size of 5/16 inch is the smallest~
That the equation could be combined into like terms
So hundreth is the 2nd number after the decimal point
that is the 6
so to round you take the numer before it so
69
if number is <u>></u>5 round up
if number is <5 round down
9 is >5 so round up
