Answer:

3) 7\frac{7}{5(n+2)}

5) \frac{9}{k+2}

7) \frac{7b}{b-9}


Step-by-step explanation:

3) \frac{7n+5*7}{5n^{2}+(5*7)n+2*5^{2}  }

\frac{7(\frac{7n}{7}+\frac{5*7}{7} ) }{5(\frac{5n^{2} }{5}+\frac{5*7n}{5}+\frac{2*5^{2} }{5}   )}

5) \frac{3^{2}(k+5) }{k+2} * \frac{1}{k+5}

7)\frac{5*7*b^{2}+7^{2*b} }{(2*5)b+2*7} / \frac{b-9}{2}

\frac{7b (\frac{5*7b^{2} }{7b} + \frac{7^{2}*b }{7b} )}{2(\frac{2*5b}{2}+\frac{2*7}{2}) } / \frac{b-9}{2}


This is my first time using the equation function, hopefully I did it correct.

This is our initial premise.

2) Linear pairs of angles are supplementary

This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.

.

4) Substitution of 1. into 3.

As with 2), this may differ based on the teacher or book. Some may prefer that you write out the equation, whereas others may be satisfied with the references as given. Check for similar examples.

Can you find the area of a parralllogram with just the length of the diagonals
nekit [7.7K]
No it is not. If you had two fixed diagonals which are attached in the center, when they move it creates different parallelograms. The area would be close to zero if they were parallel.

I think (-6,-2) because it would switch into the all negative quadrant making them both negative.

Water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. Which would not be a proportion you could use to solv
enot [183]

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

First, we need to convert 2 2/3 hours to minutes. This would be:

= 2 2/3 × 60 minutes

= 8/3 × 60 minutes

= 160 minutes

Since water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. The the gallons of water going over the waterfall in 2 2/3 hours would be:

= (162 1/2 × 2 2/3hours) / 15 minutes

= (162 1/2 × 160) / 15

= 1733 1/3 gallon
