find the sum of 3/4 and -11/4. reduce your answer to lowest terms.
To find the sum of 3/4 and -11/4, we add the numerators while keeping the denominator the same:
(3/4) + (-11/4) = (3 - 11)/4 = -8/4
The answer, -8/4, can be simplified to its lowest terms by dividing both the numerator and denominator by their greatest common divisor, which is 4:
(-8/4) ÷ 4/4 = -2/1 = -2
Therefore, the sum of 3/4 and -11/4, reduced to lowest terms, is -2.
(3/4) + (-11/4) = (3 - 11)/4 = -8/4
The answer, -8/4, can be simplified to its lowest terms by dividing both the numerator and denominator by their greatest common divisor, which is 4:
(-8/4) ÷ 4/4 = -2/1 = -2
Therefore, the sum of 3/4 and -11/4, reduced to lowest terms, is -2.
-12 + -13
-12 + -13 = -25

10.82 + (-15.96)
10.82 + (-15.96) = -5.14
it was 13 degrees C yesterday, but the temp changed by -18.6 degrees overnight. what is the temperature now?(1 point)
To find the temperature now, we need to subtract the change in temperature from the initial temperature.
13 degrees Celsius - 18.6 degrees Celsius = -5.6 degrees Celsius
Therefore, the temperature now is -5.6 degrees Celsius.
13 degrees Celsius - 18.6 degrees Celsius = -5.6 degrees Celsius
Therefore, the temperature now is -5.6 degrees Celsius.
use the additive inverse to find -492.89 - (-871.78).(1 point)
To find the expression -492.89 - (-871.78), we can use the additive inverse property, which states that subtracting a number is the same as adding its opposite.
So, we can rewrite the expression as follows:
-492.89 + 871.78
= 378.89
Therefore, the result is 378.89.
So, we can rewrite the expression as follows:
-492.89 + 871.78
= 378.89
Therefore, the result is 378.89.
determine the distance between -18.26 and -2.45 on a number line.(1 point)
To determine the distance between -18.26 and -2.45 on a number line, we subtract the smaller value from the larger value:
|-18.26 - (-2.45)| = |-18.26 + 2.45|
= |-15.81|
= 15.81
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.
|-18.26 - (-2.45)| = |-18.26 + 2.45|
= |-15.81|
= 15.81
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.
24 - (-15)
To subtract -15 from 24, we can use the additive inverse property and rewrite the expression:
24 - (-15) = 24 + 15
= 39
Therefore, the result is 39.
24 - (-15) = 24 + 15
= 39
Therefore, the result is 39.
what is 17 4/9 + 5/9 - 8 - 10?(1 point)
To simplify the expression 17 4/9 + 5/9 - 8 - 10, we first convert the mixed number (17 4/9) into an improper fraction.
17 4/9 = (17 * 9 + 4)/9 = 157/9
Now we can rewrite the expression as follows:
157/9 + 5/9 - 8 - 10
Combining like terms, we get:
(157 + 5)/9 - 18
= 162/9 - 18
To subtract fractions, we need a common denominator, which in this case is 9. So we rewrite 18 as 162/9:
162/9 - 162/9
Now, we can subtract the numerators:
(162 - 162)/9
= 0/9
Finally, we simplify the fraction:
0/9 = 0
Therefore, the result is 0.
17 4/9 = (17 * 9 + 4)/9 = 157/9
Now we can rewrite the expression as follows:
157/9 + 5/9 - 8 - 10
Combining like terms, we get:
(157 + 5)/9 - 18
= 162/9 - 18
To subtract fractions, we need a common denominator, which in this case is 9. So we rewrite 18 as 162/9:
162/9 - 162/9
Now, we can subtract the numerators:
(162 - 162)/9
= 0/9
Finally, we simplify the fraction:
0/9 = 0
Therefore, the result is 0.
solve the following word problem. the air temp at 9 a.m. is -5.8 degrees Celsius. the air temp at noon is -1.6 degrees Celsius. what is the change in the temp during these three hours? write and solve an equation to show your answer. then explain what your answer means.(4 points)
To find the change in temperature during the three hours between 9 a.m. and noon, we need to subtract the initial temperature from the final temperature.
Final temperature - Initial temperature = Change in temperature
-1.6 degrees Celsius - (-5.8 degrees Celsius) = Change in temperature
To simplify the calculation, we can rewrite the subtraction as addition by taking the additive inverse of -5.8 degrees Celsius:
-1.6 degrees Celsius + 5.8 degrees Celsius = Change in temperature
= 4.2 degrees Celsius
Therefore, the change in temperature during the three hours is 4.2 degrees Celsius.
This means that the temperature increased by 4.2 degrees Celsius from -5.8 degrees Celsius at 9 a.m. to -1.6 degrees Celsius at noon.
Final temperature - Initial temperature = Change in temperature
-1.6 degrees Celsius - (-5.8 degrees Celsius) = Change in temperature
To simplify the calculation, we can rewrite the subtraction as addition by taking the additive inverse of -5.8 degrees Celsius:
-1.6 degrees Celsius + 5.8 degrees Celsius = Change in temperature
= 4.2 degrees Celsius
Therefore, the change in temperature during the three hours is 4.2 degrees Celsius.
This means that the temperature increased by 4.2 degrees Celsius from -5.8 degrees Celsius at 9 a.m. to -1.6 degrees Celsius at noon.
