Bogdan [553]

Answer:

w=5h-8

Step-by-step explanation:

Take the original formula h=(1/5)w+(8/5)

Subtract -8/5 on both sides to isolate the w, so h-8/5=(1/5)w

Now you have to get rid of the 1/5, so multiply 5(h-8/5), the 5 in the 8/5 cross each other out. You are left with 5h-8

What is the quotient of 1.728 x 109 and 4.8 x 106 expressed in scientific notation?​
fenix001 [56]

Step-by-step explanation:

\to 1,728 \times {10}^{9}

= 1,728 \times {10}^{9}

= 1,728 \times 1.000.000.000

= 1.728.000.000

1,728 \times {10}^{9} = 1.728.000.000

\:

\to 4,8 \times {10}^{6}

= 4,8 \times {10}^{6}

= 4,8 \times 1.000.000

= 4.800.000

4,8 \times {10}^{6} = 4.800.000
