Vance used the associative property to write (4.5 m + StartFraction 7 Over 8 EndFraction) minus 9 as the equivalent expression 4

.5 m (StartFraction 7 Over 8 EndFraction minus 9). Did Vance apply the associative property correctly? Why or why not?
Yes, the terms with variables should be written first.
Yes, the terms can be regrouped and still be equivalent.
No, the order of the terms should have been changed.
No, the addition symbol was dropped in the second expression.

Answer:

the fourth choice: No, the addition symbol was dropped in the second expression

Step-by-step explanation:

1) The right operation is: (4.5m + 7/8) - 9 = 4.5m + (7/8 - 9), this is you have to keep the + operator, since you are just grouping the terms in an alternate form.

2) Droping the + operator leads incorrectly to the multiplication of the first term, 4.5m to the terms in parenthesis, instead to the addition, which is what corresponds.

Someone please answer<br> 2.1 ( x + 5 ) = 7
tatuchka [14]
Since we have the 2.1 next to the parenthesis, we need to first distribute.

2.1 * x  &   2.1 * 5

2.1x + 10.5

Then we take that and add the equals seven to the problem to move onto the next step.

2.1x + 10.5 = 7

We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.

2.1x + 10.5 = 7
       - 10.5   -10.5

2.1x = -3.5

To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.

2.1x = -3.5
/2.1     /2.1

x = 1.66666666667

Hope this helped!

Triangle R Q S is cut by line segment T U. Line segment T U goes from side Q R to side Q S. The length of Q T is 32, the length
Marizza181 [45]

The statement  that is true is option A that  is Line segment TU is parallel to line segment RS because StartFraction 32 Over 36 EndFraction = StartFraction 40 Over 45 EndFraction.

<h3>What is the line segment about?</h3>

The law of the side- splitter connote that when f the line is parallel to a side of the triangle and if that said line do intersects the other 2 sides, tt is said to divides those  given sides proportionally.

So the converse means that when the sides are proportional so therefore, the side TU is said to be parallel to the side RS.

Thus;

\frac{QT}{TR} = \frac{32}{36}  = \frac{8}{9}\\\\ \\

\\\frac{QU}{US}  =\frac{40}{45}  = \frac{8}{9}\\

Therefore,  the ratios are equal and as such TU is parallel to RS

Hence, The statement  that is true is option A that  is Line segment TU is parallel to line segment RS because StartFraction 32 Over 36 EndFraction = StartFraction 40 Over 45 EndFraction.
