Half-perimeter=length+width=width+3+width=43, 2×width=40 so width=20cm and length=23cm.
(27x + 16*8)/x+8 = 19
(27x +128) /x+8 = 19
multiply both sides by x+8
27x+128 = 19x +152
subtract 19x from both side:
8x +128 = 152
subtract 128 from both side:
8x = 24
divide both sides by 8
x = 24 /8
x = 3 pounds
Based on the information given, it should be noted that the cost of the pretzel is $0.04.
<h3>How to solve an equation.</h3>
Let the coke be represented by c.
Let the pretzel be represented by p.
Based on the information,
c = p + 2 ..... i
c + p = 2.08 ... ii
p + 2 + p = 2.08
2p + 2 = 2.08
2p = 2.08 - 2
2p = 0.08
p = 0.08/2 = 0.04
Therefore, c = 2 + 0.04 = 2.04
