This can be solve by establishing equations.
let x be the miles mrs. storey drove
y be the miles mr storey drovee
the first equation is
y = 3x
second equation
x + y = 3200
then substitute equation 1
x + 3x = 3200
4x = 3200
x = 800 miles mrs storey drove
y = 3x = 2400 miles mr storey drove
Is this for area and perimeter? If so, first make the fraction a decimal, (that would be 3.5). Then, for permeter, add 3.5 + 3.5 + 9 + 9, which is 25, for area, multiply 3.5 by 9, which is 31.5. Hope this helped!

Answer:
0.8
Step-by-step explanation:
Things to remember:
- You can add as many 0's on the end of a decimal and it will still equal the same number, as long as the 0's are on the right side of the decimal point. For example, 0.7 = 0.7000.
- The lowest value has the lowest probability
So, let's rewrite the options with the same amount of decimal points:
1.00
0.90
0.80
0.85
Now, find the value under 0.82. In this option, the lowest value is 0.80, and it is under 0.82, so it is the answer.
The answer is 8
8*2=16-4=12
