# Which line shows the first error in the solution? 5(x-5)=15 (1)       5x-25=15 (2)      5x-25=15-25 (3)  5x= -10 (4)  5x/5 = -10/5 (5) x=-2 (6) Answers: A. line 2 B line 3 C. line 4 D. line 5

5(x-5)=15 ----> 1

We remove the parenthesis by distributing 5 inside the parenthesis.

5x - 25 = 15 ----> 2

To get rid of -25, add 25 on both sides

5x - 25 + 25 = 15 + 25 ----> 3

5x = 40  ----> 4

Divide by 5 on both sides

x = 8

From the given options we can see that there is a error in line 3.

So line 3 shows the first error.

Roboto cuts diagonally across a square field to go home from school. What angle does his path make with the edge of the field? The answers are A: 39% B: 45% C: 60% And D: 90% plz help me

I believe the answer is 45 because squares cut in have 2/3 of the ends are 45 degree angles.

The points given in the table lie on a line.fund the slope of each line

for the first table
consider A(x1,y1)=A(0;3)  and B(x2;y2)=B(1;5)

the slope m= (y2-y1)/(x2-x1) = (5-3)/(1-0) = 2/1=2

for the second table
consider again A(x1;y1)=A( 0;9)  and B(x2;y2)=B(2;4)

the slope m= (y2-y1)/(x2-x1)= (4-9)/(2-0)= -5/2= -2.5

This is in decimal form already!

In the figure, a ‖ b and m∠1 = 34°.
What is m∠7?
__ °

If angle 1 is equal to 34 degrees, angle will be 34 too, because 1 and 3 are oppostite angles. And 3 and 5 are alternate interior angles, meaning they are alson equal so, angle 5 = 34. And finally , angle 5 and angle 7 are opposite angles so they are equal too, angle 7 = 34

Find three consecutive even integers such that the sum of the smallest to the largest 36

If they were all the same integer, then each one would be
1/3 of 36, and you would have

12  +  12  +  12  =  36 .

But you don't want them to all be the same number.  You
want them to be three consecutive even numbers.

Fine !  Take 2 away from the first 12, and glue it onto the last 12 .
Their sum doesn't change, but now you have

10  +  12  +  14  =  36 .
First, I would set up an equation (assuming 36 is the sum of all 3 numbers).

x+(x+2)+(x+4)=36
3x+6=36
-6   -6
3x=30
---   ---
3     3
x=10

Now, we just plug in the numbers to find the consecutive integers
10+(10+2)+(10+4)
10+12+14

So your 3 consecutive even integers are 10,12 and 14
