You can use 78 = 0.55(w) and
78/x = 55/100. They both lead to the same answer.
The answer is 3167.
First, multiply the numbers by their place values:
3 x 1000 = 3000
16 x 10 = 160
7 x 1 = 7
Then, add together the sums: 3000 + 160 + 7 = 3167
Answer:
6 hours.
Step-by-step explanation:
She has already travelled 45 miles so there's another 393-45 = 348 miles to travel. So if she continues at 58 mph she will take 348 / 58 = 6 hours.
Your answer would be (w+2)(w−10). If you want me to explain please don't hesitate to ask.
