Answer:
x = 0
Step-by-step explanation:
Solve for x:
x/5 + 5 = 5
Put each term in x/5 + 5 over the common denominator 5: x/5 + 5 = x/5 + 25/5:
x/5 + 25/5 = 5
x/5 + 25/5 = (x + 25)/5:
(x + 25)/5 = 5
Multiply both sides of (x + 25)/5 = 5 by 5:
(5 (x + 25))/5 = 5×5
(5 (x + 25))/5 = 5/5×(x + 25) = x + 25:
x + 25 = 5×5
5×5 = 25:
x + 25 = 25
Subtract 25 from both sides:
x + (25 - 25) = 25 - 25
25 - 25 = 0:
x = 25 - 25
25 - 25 = 0:
Answer: x = 0
Answer: (distributive property)
20.
1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 or 1
1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 or 1
1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 or 1
1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 or 1
1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 or 1
= 5 (total sums)
The total number of 1/5's = 25
<u>20 + 5 = 25</u>
<u>25 - 5 = </u><u>20</u>

First, distribute the 1/4.
= 1/4x + 1/4 * 16 - x
= 1/4x + 4 - x
= 1/4x + 4 - 4/4x
= 1/4x - 4/4x + 4
= -3/4x + 4

given
slope(m)=1
point=(2,-4)=(x1,y1)
we know
equation of straight line
y-y1=m(x-x1)
y+4=1(x-2)
y+4=x-2
therefore x-y-6=0 is the required equation
substituting with ax+by+c=0 we get
a=1
b= -1
c= -6
