Answer:
1.3 inches
Step-by-step explanation:
1. Determine what you already know in order to set up the equation:
1 inch = 100 miles
<em>x</em> inches = 130 miles
Solving for <em>x</em>
2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)
= 
3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)
100<em>x</em> = 130
4. Divide each side by 100 to isolate the variable.
<em>x</em> = 1.3

Answer:
D. 14.99d
Step-by-step explanation:
d represents the number of DVD's she purchased, and 14.99 was the cost for each DVD. Answer D is multiplying the variable d and the coefficient 14.99. When multiplying variables, there is no need to place a multiplication sign.
<span>Depending on the equation there can be three possible cases:
1- There can be 1 specific solution for the variable:
2x+4= 3
where x= -1/2
2- there can be an infinite amount of solutions:
2x+x-2=3x-3+1
where x=x
3- there can be no answer:
3+2x-x=5-3x+4x
where the solution doesn't exist</span>
