2(3x + 5) = 22 what is X?

2 answers:

7 0

First divide both sides by 2 so that we can get rid of the parentheses, so we get
$(3x + 5) = 11$
now subtract 5 from both sides
$3x = 6$
then finally we want x alone so we'll divide both sides by 3 and get our final answer!
$x = 2$

Suppose you deposit $12.50 into your savings account each week for 4 weeks and then withdraw $4.80 each week for the next two we

Answer:

The total change in the amount of money in my account is $ 9.60

Step-by-step explanation:

Given:

Amount of money deposited each week, $A_{d}=\$12.50$

Amount of money withdrawn each week, $A_{w}=\$4.80$

∴ Amount of money deposited in 4 weeks, $A_{dT}=A_{d}\times 4=12.50\times 4 = \$50$

∴ Amount of money withdrawn in 2 weeks, $A_{wT}=A_{w}\times 4=4.80\times 2 = \$9.6$

Now, amount of money left in the account is the difference of the two amounts.

So, amount left = $A_{dT}-A_{wT}=50-9.6=\$40.4$

Therefore, the total change in the amount of money in my account is given as:

Total change = Initial amount after 4 weeks - Final amount in the account.

Total change = $ 50 - $40.4 = $ 9.6

Use a truth table to determine whether the following is a tautology, a contradiction, or neither. ~PAP Q~QvQ

NNADVOKAT [17]

Answer:

The statement $\lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q$ is a tautology.

Step-by-step explanation:

We have the following statement $\lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q$

A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.

The simple statements from the statement given are:

$\lnot P$ , $\lnot Q$ , $\lnot P \land P$ , $\lnot P \land P \rightarrow Q$ , and $\lnot Q \lor Q$ with these you can construct the following truth table.

A tautology is a formula that is always true, it is true for every assignment of truth values to its simple components.

The last column contains only true values. Therefore, the statement is a tautology.
