Answer:
(-11)/5
Step-by-step explanation:
Simplify the following:
4/5 - 3
Put 4/5 - 3 over the common denominator 5. 4/5 - 3 = 4/5 + (5 (-3))/5:
4/5 + (5 (-3))/5
5 (-3) = -15:
4/5 + (-15)/5
4/5 - 15/5 = (4 - 15)/5:
(4 - 15)/5
4 - 15 = -(15 - 4):
(-(15 - 4))/5
| 1 | 5
- | | 4
| 1 | 1:
Answer: (-11)/5
Answer:it’s B I did the test
Step-by-step explanation:
Answer:
p = 3*[ 4p+ 2p]
Step-by-step explanation:
Total number of pens = 3 times [ 4 blue pens + 2 black pens]
If we denote the total number of pens by p then the equation becomes
p = 3*[ 4.blue + 2black]
p = 12p+6p
p = 18p
There are total 18 pens out of which 12 pens are blue and 6 pens are black.
Answer:
the limit does not exist
Step-by-step explanation:
As x approaches π/2 from below, tan(x) approaches +∞. A x approaches π/2 from above, tan(x) approaches -∞. These two limits are not the same, so the limit is said not to exist.
___
For a limit to exist, it must be the same regardless of the direction of approach.
Answer:
no solution
Step-by-step explanation:
x+y=7
x=3-y
Substitute the second equation into the first
(3-y) +y = 7
Combine like terms
3 = 7
This is never true so there is no solution
