4+|7-m|=5
|7-m|=1
7-m=1 and 7-m=-1
-m=-6 and -m=-8
m=6 and m=8

Step-by-step explanation:

Answer:
(3,2)
Step-by-step explanation:
2x-4=y
2y+3x=13
We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation
2(2x-4) +3x=13 : *distribute*
4x-8+3x=13 : *combine like terms*
7x-8=13 * add the 8 to the other side*
7x=21 *divide*
x=3
So the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3 we plug it into the other equation preferably.
2(3)-4 =y : 6-4=y : 2=y
We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.
2x-4=y 2(3)-4=(2) 2=2
2y+3x=13 2(2)+3(3)=13 13=13
Answer:
806 million years
Step-by-step explanation:
From the information given:
Firstly, we need to determine the no. of ways we can choose n many words in the dictionary & array them in
ways.
Thus, the no. of unique books possible of length till K is:

where K = 6, we have the value to be:
= 25420530373932821216635722990977
Thus, the time required to write all possible texts of 6 is:
= (25420530373932821216635722990977)/10⁶
≅ 806 million years.
