How do you do 4/5x-.4 repeating?

1 answer:

3 0

We use the algebraic way for this:
0.0¯4=x we manipulate the equation by multiplying it by 10 and 100.
0.¯4=10x
4.¯4=100x
We subtract the second equation from the third equation to get:
4=90x
Therefore,
490=x or
245=x
so the answer is

2/45

8(4n + 3) = – 72 show your work

AfilCa [17]

Answer: n= −3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8(4n+3)=−72

(8)(4n)+(8)(3)=−72(Distribute)

32n+24=−72

Step 2: Subtract 24 from both sides.

32n+24−24=−72−24

32n=−96

Step 3: Divide both sides by 32.

32n/32 = −96/32

n=−3
