Answer:
x=11 degrees
Step-by-step explanation:
45+4x+1=90
46+4x=90
4x=44
x=11
Squaring both sides of the given equation: w^2=7w, or w^2-7w=0.
w^2-7w=0 can be factored: w(w-7)=0. Then, w=7 or w=0. Both 0 and 7 are solutions of this equation.
Assume that the bank balance started at zero. Enter the income and outgo in chronological order: $300 - $50 - $75 + $225
Find the sum. This sum will represent the amount left in the account after the $225 deposit:
$250 - $75 + $225, or
$175 + $225 = $400 The final balance will be $400.
