You need to add two mixed numerals.
One is positive and one is negative.
To add a positive number and a negative number, first take the absolute value of both, making them both positive. Then subtract the smaller absolute value from the larger absolute value. Finally, the sign of the answer is the same sign as the number that has the larger absolute value.
The numbers are -4 5/8 and 2 1/8
Take absolute values:
|-4 5/8| = 4 5/8
|2 1/8| = 2 1/8
Subtract the smaller absolute value from the larger absolute value.
4 5/8 - 2 1/8 = 2 4/8 = 2 1/2
The greater absolute value is 4 5/8.
Since the number with the larger absolute value was -4 5/8, a negative number, the answer is negative, -2 1/2
-4 5/8 + 2 1/8 = - 2 1/2
To actually form a triangle, the two SMALLEST sides, have to be bigger than the BIGGEST number, when added together.
A.) Can be a triangle
B.)Can be a triangle
C.)Can be a triangle
D.)Can't be a triangle
2+10=12, and 12 is not bigger than 20.
Thus, D, is your answer.
Answer:
20 hours
Explanation:
For this problem, since her hourly rate remains the same, we can set up a proportion to find the amount of hours she worked to make $368.00. The following is how to find the amount of time with proportions:
368.00/404.80 = x / 22
(22 * 368) / 404.80 = x
20 = x
Hence, she would need to work 20 hours to make $368.00.
Cheers.
3 3/4 is the correct answer
<2=40° <11=60°
Because <1 was 140°, 2 is 40°. 40°+80°=120°
180°-120°=60°
