Answer:
-2.9
Step-by-step explanation:
You are really subtracting. Note that if you have a positive & negative sign directly next to each other, you will subtract:
-1.2 + (-1.7) = -1.2 - 1.7 = -2.9
-2.9 is your answer.

Convert 8 1/2 to 8.5 and 6 3/10 to 6.3, and then multiply 8.5 by 6.3. Answer:
53.55, or, if you reduce 55/100, 53 11/20.
For CO2 there is one atom of carbon and two atoms of oxygen. For H2O, there is one atom of oxygen and two atoms of hydrogen.
Answer: Assuming the riders starts at the position (20, 0) on the x-axis, the exact position of the rider will be (20cos75, 20sin75) or about (5.18, 19.32).
The angle for 5pi/12 radians is 75 degrees. Therefore, to find the position we can use the sine and cosine of 75 to find the x and y value of the coordinate.
For the y-value, we can write and solve:
sin75 = x/20
For the x-value, we can write and solve:
cos75 = x/20
