$5.49 per hamburger x 2 hamburgers=$10.98
$1.75 per soda x 4 sodas=$7
$10.98+$6.25+$12.99+$7=$37.22
$37.22 x 0.07 sales tax=approximately $2.61
$37.22 x 0.2 tip=approximately $7.44
$37.22+$2.61+$7.44=$47.27

so
Answer:
a−4b
Step-by-step explanation:
Combine Like Terms:
=4a+−6b+−3a+2b
=(4a+−3a)+(−6b+2b)
=a+−4b
have a great day
Answer:
4 cm
Step-by-step explanation:
Perimeter = 18cm
θ = 2.5 radian
s = rθ, s = Arc length
Perimeter of Sector, P = arc length, s + 2r
Perimeter = rθ + 2r
r = Radius
18cm = r(2.5) + 2r
18cm = 2.5r + 2r
18cm = 4.5r
r = 18 /4.5
r = 4
