To make this easier to read, I'll be substituting 1/2 for .5; they mean the same thing, but it's less confusing to type it in its decimal form.
7x + .5 + 6x - 9.5
Combine like terms (x's can be added together, and so can reg. numbers)
(7x + 6x) + (.5 - 9.5)
13x - 9
First add the whole numbers (2+1=3)
Then add the fractions (5/6 + 2/6 = 7/6)
Make the fraction a mixed fraction (7/6 = 1 1/6)
Then put them together
The answer is 4 1/6
Answer: 504
Step-by-step explanation:
Area: 4 triangles + square
Triangle area = 1/2 x b x h
Square = side x side
4(1/2 x 12x 15) + 12x12
= 504
Natalie would have been making a mistake from the beginning because any non-zero expression raised to the power of zero is one.
So she would have been making a mistake from step one
Odds of rolling a 6 is 1/6. the odds of rolling another 6 is still 1/6. the number on the first toss has no effect on the second (this is called independent events) so you multiply the probabilities together
1/6 * 1/6 = 1/36
