Answer:
$90
Step-by-step explanation:
You pay $20 the first day, then subtract $2 each day. Add the numbers up to get the total. 20+(20-2)18+(18-2)16+(16-2)14+(14-2)12+(12-2)10=90
Answer: $90
b
x=3/7
6-2x=3+5x
subtract 5x from both sides
6-2x-5x=3
subtract 6 from both sides
-2x-5x=3-6
add like terms
-7x=-3
divide both sides by -7
lolSolve y=x^2+2 for x.A.B.C.D
x =-5
