Lunna [17]2 years ago
4 0

Answer:

5/17

Step-by-step explanation:

If we do the multiplication first, we get:

\frac{4-(12\div-12)}{13+(-8\div-2)}

If we do the division next, we get:

\frac{4+1}{13+4} = 5/17

Marty is saving money to buy a new computer. He received $200 for his birthday and saves $150 of each week’s paycheck.

Yes it does, it is proportional because it increases by the same amount at a constant time (which is each week's paycheck). The constant is the 150. i may be wrong sorry if so.

HELP QUICK!!
MA_775_DIABLO [31]

Answer:

5

Step-by-step explanation:

The clothing store already sold $300 .

They need to sell x jeans to get to $500.

$500 - $300

$200

They’re $200 short of their goal.

A pair of jeans cost $40

Therefore x40 = $200

x = 200/40

x = 5

So ,they need to sell 5 pairs of jeans to hit their $500 target

g100num [7]

Answer:

Step-by-step explanation:

Hmmmmm you did not give the full equation for the original line.

However, parallel lines have identical slopes. Whatever coefficient (m) is associated with the x value, will be the slope of the parallel line when the equation is put in the form

y = mx + b

Show that each of these conditional statements is a tautology by using truth tables. a) [¬p ∧ (p ∨ q)] → q b) [(p → q) ∧ (q → r)
nlexa [21]

Step-by-step explanation:

To show that a statement is a tautology using truth table - is to show that all the entries in the expression are truths T.

We can do this by taking each statement, expression by expression. For example, to show that

[~p ∧ (p ∨ q)] → q

is a tautology, knowing we have 3 columns, we have 2^3 = 8 rows. We start by putting putting truth values for p, q, and r respectively

Next, we find ~p, then find (p ∨ q), then find ~p ∧ (p ∨ q), before finally arriving at the required [~p ∧ (p ∨ q)] → q

TERMINOLOGIES AND SYMBOLS

- T means Truth

- F means False

- ~p means negation of p.

~p is F if p is T, and vice versa

- ∧ means conjunction.

p ∧ q is T only if p is T and q is T.

- ∨ means disjunction.

p ∨ q is T if either p or q is T.

- → is for conditional 'if then'

p → q is T if both p and q are T, or both p and q are F, or p is F and q is T, otherwise, it is F.

THE STEP BY STEP WORKINGS FOR THE STATEMENTS GIVEN ARE IN THE ATTACHMENT.
