<h3>Answer:  1.8x - 4</h3>

==========================================================

Explanation:

Subtract the two expressions

Tomas - Angie = (3x) - (1.2x+4) = 3x - 1.2x-4 = 1.8x-4

This represents how many more miles Tomas jogged compared to Angie.

-------------

A more concrete example would be to say hypothetically

Tomas = 10 miles

Angie = 4 miles

So Tomas - Angie = 10-4 = 6 means he jogged 6 more miles than Angie.

That's why we subtracted. The order of subtraction matters. Saying 10-4 is different from 4-10.

Greeley [361]

Answer:

The equation showing the relationship between the number of yards of yarn Paula has and the number of hats she can knit is ;

h = 42y

Step-by-step explanation:

Here, we want to write an equation;

From the question, we are told that the number of hats h that can be knitted is directly proportional to the amount of yarn in yards

Since it is a proportional relationship;

h = k * y

where k is the constant of proportionality given as 42

Hence;

h = 42 * y

h = 42y
