Ok, so abc is a 3 digit number
easy
if we do
abc=x
then we have
750-x=x
add x to both sides
750=2x
divide both sides by 2
375=x
abc=375
check
750-375=375
correct
abc=375
0.abc=0.375
0.abc=0.375
that was fun
Answer:
The answer would be 508
Step-by-step explanation:
The answers are MK and PY and AH.
Let the balance = Y and the number of weeks = x
She takes out 15 per week, so multiply 15 by x ( the number of weeks) to get 15x.
You would then want to subtract that from the amount she started with in her account.
The equation becomes: Y = 150 - 15x
