4 people = 480 grams of pasta
1 person = 480 ÷ 4 = 120 grams of pasta
14 people = 120 x 14 = 1680 grams of pasta
1680g = 1680 ÷ 1000 = 1.68 kg
Answer: 1.68 kg of pasta
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.
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

Dividing both sides by 2

Putting x=76 in Eqn 1

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