Answer: x=40

Step-by-step explanation x-0.3x=28

Add similar elements x-0.3x=0.7x

0.7x=28

Multiply both sides by 10

0.7x · 10= 28 · 10

Refine

7x=280

Divide both sides by 7

Simplify

x = 40

What is 12 m/mi = cm/s

yarga [219]

1 Cancel m.

12i=c*m/s

2 Use rule a*b/c = ab/c

12i=cm/s

3 Multiply both sides by s.

12is=cm

4 Divide both sides by 12.

is=cm/12

5 Divide both sides by i

s=cm/12/i

6 Simplify cm/12/i

s=sm/12i

Answer and Step-by-step explanation:

The answer is H.

$f(x) = \frac{1}{3} (4)^x$

When 4 is brought to the power of a number it gets multiplied to the numerator of 1/3. When inputting those numbers for x in this function, the result is what is shown on the table, meaning the function is correct.
