Determine if the statement is true or false.
seropon [69]

Answer:

False

Step-by-step explanation:

There are two concepts:

1. Row Echelon Form: There can be more than two <em>row echelon forms</em> of a single matrix, so different sequences of row operations can lead to different <em>row echelon forms</em> of a single matrix.

2. Reduced Row Echelon Form: It's unique for each matrix, so different sequences of row operations always lead to the same <em>reduced row echelon form</em> for the same matrix.

At a hockey game a vendor sold a combined total of 110 sodas and hot dogs. The number of hot dogs sold was 42 less than the numb
jasenka [17]

76 sodas and 34 hot dogs were sold by the vendor.

Step-by-step explanation:

Given,

Total sodas and hot dogs sold = 110

Let,

x be the number of sodas sold

y be the number of hot dogs sold

According to given statement;

x+y=110     Eqn 1

y = x-42    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x+(x-42)=110\\x+x-42=110\\2x=110+42\\2x=152

Dividing both sides by 2

\frac{2x}{2}=\frac{152}{2}\\x=76

Putting x=76 in Eqn 1

y=76-42\\y=34

76 sodas and 34 hot dogs were sold by the vendor.
