< means 'less than'. 3.5 is less than 4.5, so A is correct. Since -4.5 is NEGATIVE it is less than 0. As for C, since both numbers are negative, it would be the seemingly 'smaller' number that is actually bigger. It may help to think of the numbers on a number line. In the negatives, the numbers start to go in reverse, so the further from 0 a negative number is, the smaller it is. -4.5 IS LESS than -3.5. All answers are correct.
For the first expression
15 + 2d
A possible word problem would be this:
A person saves $2 per day of money. Before he started saving, he had $15 dollars set aside. Look for the expression that expresses the total amount of money saved in terms of the number of days passed
The second expression is
200 - 2m
A possible word problem would be this:
The distance from school to the park is 200m. A kid riding a bike is traveling at a speed of 2m/s from the school to the park. Write an expression for the distance remaining between the park and the kid.<span />
A circle is made up of 360 degrees. Lets find the decimal form of each part of the circle.
White: 122.4/360 = 0.34
Red: 115.2/360 = 0.32
Silver: 68.4/360 = 0.19
Blue: 54/360 = 0.15
Now, solve for the car color that is not red or blue.
1 - (0.15 + 0.32)
1 - (0.47)
0.53
Therefore, the answer is C.
Best of Luck!
The answer to the question is 5 so CD=5
