We are given intersecting lines. The measures of a pair of angles forming vertex angles, are 2x+6° and 96°.

The measure of 2 vertex angles is equal, so we solve the equation:

2x+6°=96°, subtract 6° from both sides of the equation
2x=90°,   divide both sides of the equation by 2
x=45°

Kelsey can buy 2 pounds of apples for 7$. Write an equation to represent the cost, c, for a, pounds of apples.
zmey [24]

\huge\boxed{c=3.5a}

First, we need to find how much a single pound of apples costs.

Do this by dividing.

\frac{\$7}{2\ \text{lbs.}}\div\frac{2}{2}=\frac{\$(7\div 2)}{(2\div 2)\ \text{lbs.}} = \frac{\boxed{\$3.50}}{1\ \text{lb.}}

Now, write an equation.

\large\boxed{c=3.5a}

This represents that the cost equals 3.5 times the number of apples.
