igomit [66]

Answer:

A) 1:4

Step-by-step explanation:

#We first calculate the campus' area:

a=lw\\\\=\frac{1}{4}\times \frac{1}{2}\\=0.125 \ mi^2

#We then calculate the campus' map area in square ft:

A=lw\\\\=0.5 \times 1\\\\=0.5 ft^2

Ratio is a comparison between two dimensions:

Ratio=\frac{0.125}{0.5}\\\\=0.25\\\\=\frac{1}{4}\\\\=1:4

Hence, the ratio of the area in square miles of the campus to the area in square feet of the map is 1:4

<h3>Multiplication Property of Equality is the missing reason</h3>

<em><u>Solution:</u></em>

Given that,

five thirds times x plus 2 equals negative 3

Therefore,

\frac{5}{3}x + 2 = -3

<em><u>Multiplication Property of Equality</u></em>

The Multiplication Property of Equality means that, if both sides of an equation is multiplied by same number, the equation still remains equal

\frac{5}{3}x + 2 = -3

Multiply both sides by 3

3(\frac{5}{3}x + 2) = -3 \times 3\\\\5x + 6 = -9

<em><u>Subtraction Property of Equality</u></em>

The Subtraction Property of Equality means that, we can subtract the same number from both sides of equation and the equation will still be true

5x + 6 = -9

Subtract 6 from both sides

5x + 6 - 6 = -9  - 6

5x = -15

<em><u>Division Property of Equality</u></em>

The Division Property of Equality means that, if both sides of an equation is divided by same number, the equation still remains true

5x = -15

Divide both sides by 5

x = -3
