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

Answer:
37.74
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. The one applicable here is ...
Sin = Opposite/Hypotenuse
sin(32°) = 20/x
x = 20/sin(32°)
x ≈ 37.74
Since the measure of angle DOC = 44 degrees and it's the central angle of arc DC, the measure of arc DC = 44 degrees
Answer:
-4/4+160% of +1/5= -0.68 or 8/25
Step-by-step explanation:
-4/4+160% of +1/5
-1 + 160% of + 1/5
-1 + 160% of + 0.2
-1 + 0.32
-0.68 as a decimal
and
8/25 as a fraction
Answer:
see explanation↓
Step-by-step explanation:
We are given the following equation of a line:
To determine the x-intercept we must set "y = 0":
Now, we divide both sides by 2:
Therefore, the "x" intercept is -10.
To determine the y-intercept we set "x = 0":
Now, we divide both sides by -4:
Therefore the y-intercept is 5.
