The length of the other piece is 38 inch.
Step-by-step explanation:
Given:
A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other.
Now, to find the length of the other piece.
Let the length of the other piece be .
And the length of one piece be .
The total length of the pipe =
According to question:
⇒

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.
