Answer: F-23=45
Step-by-step explanation:
The addition property of equality means that if:
A = B
then we can add the same thing in both sides of the equation, and the equality will remain balid, so:
A + C = B + C.
Then, the correct answer is the last option:
if
F - 23 = 45
Then we can add the same number to both sides, we can add 23 to both sides and in this way isolate F:
F - 23 = 45
(F - 23) + 23 = 45 +23 = 68
F + (23 - 23) = 68
F = 68
After every month's withdrawals, 4/5 of the original amount at the start of the month will remain. The amount at the start of every month will change. Thus:
an = 4/5 (an-1) ; where a1 = 500.
If the marker is 0.13cm, then it is 13 millimeters.
5p - 3q = -39
- (-2p - 3q = 3)
==> 7p = -42 ==> p = -6
==> p = -6
-2(-6) - 3q = 3 ==> 12 - 3q = 3
==>p = -6
-3q = 3 - 12 ==> -3q = -9
==> p = -6
q = 3
