Answer: 6 rooms

Step-by-step explanation:

Michael spends 1/2 an hour in every 1 room he cleans. This means that the number of 1/2 hour segments spent cleaning is equal to the number of rooms he cleans. If he cleaned for 3 hours, you can find the number of 1/2 hour segments within that time. One hour contains two 1/2-hour segments, since 1/2 hour + 1/2 hour = 1 hour. This means that 3 hours contains six 1/2 hour segments. Again, there is one 1/2 hour segment that corresponds to each room, so he cleaned a total of six rooms.

Evaluate each expression for g = -7 and h = 3 and match it to its value.

Molodets [167]

The given expressions are solved and matched

<h3>Solution:</h3>

To match the given expressions we need to solve the expressions with the given values of g and h and find their value.

Given that g = -7 and h = 3

$\begin{array}{l}{\text { 1) } g+h=-7+3=-4} \\\\ {\text { 2) } g-h=-7-3=-10} \\\\ {\text { 3) } h-g=3+7=10} \\\\ {\text { 4) } g h=-7 \times 3=-21} \\\\ {\text { 5) } g+h^{2}=-7+3^{2}=-7+9=2} \\\\ {\text { 6) } g^{2}-h=(-7)^{2}-3=49-3=46}\end{array}$

-37= n/23 what is n?

Vlada [557]

-37 = n
 23

to solve for n, undo what is happening to the n. if the n is being divided by 23 to get -37, then multiply both sides by 23 to figure out what n is.

-37 * 23 = n * 23
 23
