Answer:

child's is $14

adult is $23

Step-by-step explanation:

3c + 1a = 65

3c + 3a = 111

a = 65-3c

3c + 3(65-3c) = 111

3c + 195 -9c = 111

-6c = -84

c = 14

3(14) + a = 65

42 + a = 65

a = 23

maxonik [38]

Answer:

As Per Provided Information

Area of given square slice of cheese is 25 square inches .

We have been asked to determine the perimeter of the slice of cheese .

First we will find the side of square slice of cheese .

Let us assume the side of square slice of cheese be s .

Now Let's Solve

\boxed{\bf  \:Area_{(Square)}  = {Side}^{2}}

Substituting the value and we obtain

\sf \longrightarrow \: 25 =  {s}^{2}  \\  \\  \\  \sf \longrightarrow \:  \sqrt{25}  = s \\  \\  \\  \sf \longrightarrow \: s \:  = 5 \: inch

So, the side of square slice cheese is 5 inch

Now let's calculate the Perimeter of cheese

\boxed{\bf  \: Perimeter_{(Square)} = 4 \times side}

Substituting the value we obtain

\longrightarrow \sf \: Perimeter_{(Square)}  = 4 \times 5 \\  \\  \\ \longrightarrow \sf \: Perimeter_{(Square)}  =20 \: inches

<u>Therefore</u><u>,</u>

  • <u>Perimeter </u><u>of </u><u>square </u><u>slice </u><u>of </u><u>cheese </u><u>is </u><u>2</u><u>0</u><u> </u><u>inches </u><u>.</u>
