1) Given binomials:

First binomial 7r - 5
Second binomial 5r + 8

2) To pass from 7r to 5r you have to subtract 2r, so the first term of the binomial to be subtracted is 2r

3) To pass form - 5 to + 8, you have fo subtract  - 13

4) So the answer is 2r - 13, option b.

Which property is illustrated by the following statement statement
Zigmanuir [339]

Answer:

C) Symmetric

Step-by-step explanation:

The symmetric property is the idea that if A = B, then B = A. Flipping the equation around doesn't matter.

It's like saying 2+3 = 5 is the same as 5 = 2+3. We can extend the symmetric property to not only deal with equations, but include congruence statements as well.

At a hockey game a vender sold a combined total of 105 sodas and hot dogs. The number of sodas sold was 39 more than the number
yKpoI14uk [10]

Answer:

<em>Hot dog sold = 33</em>

<em>Sodas Sold = 72</em>

Step-by-step explanation:

<u><em>Given:</em></u>

<em>At a hockey game a vender sold a combined total of 105 sodas and hot dogs. The number of sodas sold was 39 more than the number of hot dogs sold</em>

<u><em>To Find:</em></u>

<em>Number of soda/hot dog sold</em>

<u><em>Solve:</em></u>

<em>h + ( 39 + h ) = 105</em>

<em>h + 39 + h = 105</em>

<em>2h + 39  = 105</em>

<em>h + 19.5 = 52.5</em>

<em>h = 52.5 - 19.5 </em>

<em>This as a system does not use any inequality. "39 more than" means, +39.</em>

<em>h = 33    meaning    d= 72</em>

<em />

<em>Add to check Answer:</em>

<em>33 + 72 = 105</em>

<em>Thus,</em>

<em>Hot dog sold = 33</em>

<em>Sodas Sold = 72</em>

<em />
