180 divided by what equals 4

45

Step-by-step explanation:

Hi,

We can set up an equation where "what" is represented by any number or "n."

We have:

180 ÷ n = 4

We can represent "180 ÷n" as .

= 4

We multiply both sides by n:

And, then, we simplify:

Divide both sides by 4:

Thus, .

Also note that this is just 180 divided by 4. My solution is a step-by-step longer one.

Hope this helps!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
