3w + 6 = 21 \\ 3w = 15 \\ w = 5

Hey there!

\mathsf{3w + 6 = 21}

<h3>SUBTRACT 6 to BOTH SIDES </h3>

\mathsf{3w + 6 - 6 = 21 - 6}

<h3>CANCEL out: 6 - 6 because that gives you 0 </h3><h3>KEEP: 21 - 6 because it helps you solve for w </h3>

\mathsf{21 - 6 = \boxed{\bf 15}}

<h3>NEW EQUATION: \mathsf{3w = 15}</h3><h3>DIVIDE 3 to BOTH SIDES </h3>

\mathsf{\dfrac{3w}{3}=\dfrac{15}{3}}

<h3>CANCEL out: \mathsf{\dfrac{3}{3}} because that gives you 1</h3><h3>KEEP: \mathsf{\dfrac{15}{3}} because that gives you the value of w</h3><h3>NEW EQUATION: \mathsf{\dfrac{15}{3}=w}</h3>

\mathsf{\dfrac{15}{3}=\boxed{\bf 5}}

\boxed{\boxed{\large\textsf{Therefore, your answer: \huge \bf w = 5}}}\huge\checkmark

\large\text{Good luck on your assignment and enjoy your day!}

A homeowner has two smoke detector alarms installed, one in the dining room (adjacent to the kitchen) and one in an upstairs bed
cestrela7 [59]

Answer:

0.97

Step-by-step explanation:

Given that a homeowner has two smoke detector alarms installed, one in the dining room (adjacent to the kitchen) and one in an upstairs bedroom (above the kitchen). If cooking produces smoke in the kitchen, the probability of setting off the dining room alarm (D) is .95. The probability of setting off the bedroom alarm (B) is .40.

Both alarms are independent of each other.

Probability for smoke detection=P(any one alarm rings)

=P(Kitchen alarm sets off)+P(bed room alarm sets off)-P(Both sets off)

Since both are independent

P(Both) = 0.95*0.40\\=0.38

Probability for smoke detection

= 0.95+0.40-0.38

=0.97

Grace is practicing free throws. The probability that she will shoot the ball into the basket is 5/9 . What is the probability t
Naddika [18.5K]

Answer:

There is a 25/81 probability that Grace will make both of her next two shots.

Step-by-step explanation:

The probability of her making the first shot is 5/9.

The probability of her also making the shot after that is still 5/9, that does not change.

To find the probability of both of those events, multiply the fractions.

5/9 * 5/9

25/81.
