<u>Answer:</u>
19.15
<u>Step-by-step explanation:</u>
16.80 x 5% = 0.84
16.80 - 0.84 = 15.96
15.96 x 20% = 3.19
15.96 + 3.19 = 19.15
Total cost = Price of juice + price of chocolate + tax = 10 + 10 + [(16/100) x 20]
= 20 + 3.2
= $23.2
Since they are congruent, cpctc,
just set the congruent parts equal to each other.
so 2x-20=30
and
15=3y-9
Answer:
Ratio of sweaters to dresses = 8 : 5
Sum of ratios = 13
Let number of sweater + dresses = x
Distributive property
a(b+c)+ab+ac
a(b-c)=ab-ac
(6z^2-4z+1)(8-3z)
move for nicety
(8-3z)(6z^2-4z+1)
distribute
8(6z^2-4z+1)-3z(6z^2-4z+1)=
48z^2-32z+8-18z^3+12z^2-3z=
-18z^3+48z^2+12z^2-32z-3z+8=
-18z^3+60z-35z+8
