Answer:

The perimeter of ABC is 36 feet

Step-by-step explanation:

ABC is Similar/in ratio to DEF.

Using the side BC, we can tell that it is corresponding to side EF.

This makes the ratio between the two sides 15:5 or, 3:1

This means that the ratio of ABC and DEF's perimeters is 3:1 feet

Because we know the perimeter of DEF-12 ft- We can substitute this number in the ratio which means that 3(12):12 is the ratio of the perimeters

This means that the perimeter of ABC is 3*12, or 36 feet

Answer:

$\Huge\boxed{z$

Step-by-step explanation:

Hello There!

Once again we need to isolate the variable using inverse operations

to get rid of the -8.2 we add 8.2 to each side

-8.2+8.2 cancels out

-9.7+8.2=-1.5

now we have

-1.2z>-1.5

now we wan to get rid of the -1.2

to do so we want to divide each side by -1.2

$\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25$

Remember we have to flip the inequality sign because we're dividing by a negative number

we're left with

z<1.25
