Solve for w in the equation: 0.4w + 2.45 = 8.75
ASHA 777 [7]

Answer:

w= 15.75 or 15 3/4

Step-by-step explanation:

So I would multiply 100 on both sides to get rid of the decimals so I’d end up with 40w+245=875

Now solve it by subtracting 245 on both sides.

40w=630

now divided 40 on both sides

15 3/4

Final answer 15 3/4 or 15.75

We write this in standard form or scientific notation.

5,560,000,000 years old = 5.56 × 10⁹ years old
