=

Answer 1

Answer:

week 1 < week 2

The graph in the attached figure

Step-by-step explanation:

we know that

Week 1

The water level is 1.4 cm

Week 2

The water level is 1 1/2 cm

Convert to decimal number

Remember that

$1\frac{1}{2}=1+\frac{1}{2}=1+0.5=1.5\ cm$

Week 3

The water level is -2.1 cm

Compare the values of week 1 and week 2

1.4 cm is less than 1.5 cm

so

The symbol is <

1.4 < 1.5

week 1 < week 2

The graph in the attached figure

Answer 2

Week 1 ✔ < Week 2
