Difference = subtract
29028-(-485) if you subtract a negative the sign changes to positive and the subtraction changes to addition so ur answer is 29513
Answer:
48
Step-by-step explanation:
180- 59- 52 = 69
Therefore,
69 + x + 63 = 180
x = 48
Thenks and mark me brainliest :)
Answer:
step 2
and then also in step 3 compensating the error in step 2
Step-by-step explanation:
I think I just answered this for another post.
sin(a - b) = sin(a)cos(b) - cos(a)sin(b)
so, step 1 is correct :
sin(A - 3pi/2) = sin(A)cos(3pi/2) - cos(A)sin(3pi/2)
but step 2 suddenly and incorrectly switched that central "-" to a "+".
yes, sin(3pi/2) = -1, but that is still an explicit factor in step 2. so it was not used to flip the central operation from subtraction to addition, and therefore this change was a mistake.
then, in step 3, another error was made by just ignoring the "-" sign of "-1" and still keeping the central "+" operation. this error compensated for the error in step 2 bringing us back by pure chance to the right result.
Ok so,
20*2= 40
20*1/2=10
40+10=50
So Johncan travel 50 km in 2 1/2 hours.
Hope this helps :)
Answer:
-18
Step-by-step explanation:
If the function is -2
then the answer would be
-2
