The simplification of the expression 5t + (t - 3) - [(7t + 5) - (8 - 3t)] using PEMDAS rule is -4t.
Thus, option 1 is correct.
A method of reducing an expression, equation, or problem to a more concise or straightforward form is referred to as simplification.
Initially the small bracket then curly brackets and at last large brackets are required to solve according to the laws of simplification using PEMDAS rules.
The given expression can be simplified as:
5t + (t - 3) - [(7t + 5) - (8 - 3t)]
5t+t-3-[7t+5-8+3t]
5t+t -3-7t-5+8-3t
-4t
The simplification of the expression 5t + (t - 3) - [(7t + 5) - (8 - 3t)] is -4t.
Thus, option 1 is correct.

Which equation can be used to find the first integer?
0 3x + 6 = 72
0 3х + 72 = 2х +6
03x = 2х +6
2x + 64 = 72
Answer:
3x + 6 = 72
Step-by-step explanation:
x + x + 2 + x + 4 = 72
Answer:
1. One way to show that a statement is not a good definition is to find a counterexample. A counterexample refers to an exception to the rule, if we deduct that exception is true, then the proposition is completely false. In this case, we have to find an exception to the definition, if the exception is true, then the definition is not true.
2. The option that show a true conditional is the fourth: If it's raining, then the humidity level is 100%. This shows the correct logical conditional, other options are not logical. In this case, the hypothesis is "if it's raining", and the conclusion is "the humidity is 100%". This is the right order, because humidity derive from raining, not the opposite.
The true conditional with a correctly identified hypothesis is:
If it is raining, then the humidity level is 100%.
Hypothesis: It is raining.
Conclusion: The humidity level is 100%.
1. One way to show that a statement isn't a good description is to find a counterexample.
A counterexample refers to an exception to the rule, if we abate that exception is true, also the proposition is fully false. In this case, we've to find an exception to the description, if the exception is true, also the description isn't true.
2. The option that show a true tentative is the fourth If it's raining, also the moisture position is 100.
This shows the correct logical tentative, other options aren't logical. In this case, the thesis is" if it's raining", and the conclusion is" the moisture is 100". This is the right order, because moisture decide from raining, not the contrary.

Givendecimals like 0.5 and 0.3 are rational numbers because they are terminating decimals and can be written as p/q
Rational numbers are numbers which can be written in the form p/q , where p and q are integers ,q≠0, highest common factor of p and q is 1.
The decimal expansion of rational number are terminating decimal expansion or non terminating and recurring decimal expansions.
Examples of rational number: 1/2 , 3/4, 13/2, 0.125,0.5, 0.55555....,
0.1212121212.....
As the given decimals 0.5 and 0.3 have terminatingdecimal expansion therefore they are rational numbers.
The rational form of 0.5 and 0.3 are
0.5 = 5/10 = 1/2
∴ 0.5 is written as p/q with p= 1 and q =2≠0 , p and q are coprime
0.3 = 3/10
∴ 0.3 is written as p/q with p= 3 and q =10≠0 , p and q are coprime
Therefore, 0.5 and 0.3 are rational numbers.
