Answer:
Each hotdog costs $1.65
Each juice drink costs $1.05
Step-by-step explanation:
Let's begin by letting represent the number of hot dogs and
the number of juice drinks.
The Baxter family bought 6 hot dogs and 4 juices for $14.10.
The Farley family bought 3 hot dogs and 4 juices for $9.15.
Now, we subtract these equations.
Since has reversed coefficients, it gets eliminated. Now solve for x.
NOW, we find y by substituting x with 1.65 (in either equation).
We'll use the first equation.
= 1.65
= 1.05
represents hotdogs and
represents juice drinks.
Therefore, each hotdog costs $1.65 and each juice drink costs $1.05.

<u>In a parallelogram,</u>
⇒the angles adjacent to each other
⇒ are of the same measure
⇒so
∠A = ∠C
∠B = ∠D
<u>Let's solve</u>:
- ∠A = ∠C
- ∠B = ∠D
<u>Let's check</u>:
⇒ for all quadrilaterals like a parallelogram
⇒all the angle measures added up to 360, so:
<u>Thus</u>:
<u>Answer: w = 20 and z = 15</u>
