Answer:
Elena's move will lead to the solution of the problem
Step-by-step explanation:
To solve the equation 7.5d=2.5d, Lin divides each side by 2.5d, and Elena subtracts 2.5d from each side. Will both moves lead to the solution? Explain your reasoning
Given:
7.5d = 2.5d
Lin divides each side by 2.5d, Lin:
7.5d / 2.5d = 2.5d / 2.5d
3 = 1
This can not be the solution to the problem because 3 can not be Equal to 1
Elena subtracts 2.5d from each side
7.5d = 2.5d
7.5d - 2.5d = 2.5d - 2.5d
5d = 0
This can lead to the solution of the problem
Elena's move will lead to the solution of the problem
Answer: angle 1 = 110 degrees
This is because angle 1 and the red 110 degree angle are corresponding angles.
They correspond to one another due to the fact they are both in the southwest corner of each 4-corner angle configuration (which is the result of crossing two lines)
Corresponding angles are congruent only when we have parallel lines like this.
Answer:
Table C
Step-by-step explanation:
To find the constant of proportionality, you need to divide y by x
Table A has a constant of proportionality of 
<em>which is 0.3333 repeating</em>
Table B has a constant of proportionality of 
<em>which is 0.6</em>
Table C has a constant of proportionality of 
<em> which is 0.3</em>
Well first we want to divide 1 by 3 , which is 0.3 , Now we need to divide 4 by 5 which is 0.8 .
We have our answers but 7 needs to be added by their sum so lets put them together by adding them : 0.3 + 0.8 = 1.1.
Now lets add 7 and 1.1 all together , which is 8.1.
