Answer:
Im assuming you solve 17x plus 11 then add 18x +4.
Step-by-step explanation:
G=number of words on george's page
b=number of words on bill's page
c=number of words on charlie's page
george has 2 times as many as bill's age
g=2b
bills contains 50 less than charlie
b=c-50
if each person can type 70 words per minute, after 1 minute (that is an additional 70 words for each person)
the difference between twice nmber of words on bill's page and the number of words on charlie's page is 220
so
that is after increase of 70 words
2(b+70)-(c+70)=220
and
b=c-50
subsittute
2(c-50+70)-(c+70)=220
2(c+20)-c-70=220
2c+40-c-70=220
c-30=220
c=250
charlie had 250 initially
b=c-50
b=250-50
b=200
bill had words 200 initially

Answer:
m=-1
Step-by-step explanation:
m=-(4+m)+2
m=-4-m+2
m+m=-4+2
2m=-2
m=-2/2
m=-1
Answer
Y=1/2x-3
Explanation
The general equation of a straight line is the form
Y = mx + c
where m ⇒slope of the line.
In the equation given, we make y the subject of the formula then we arrange the equation to resemble y=mx+c.
6y-3x=-18
6y = -18 + 3x
y = -18/6 + 3x/6
-3 + (1/2)x
y = (1/2)x - 3
N is a placeholder for a number. In this case, it is 4
We will replace every copy of 'n' with '4' and then simplify
So n+8 turns into 4+8 which simplifies to 12
Is 12 less than or equal to 13? Yes it is. Specifically it is less than 13. So n = 4 is part of the solution set.
Here is how you'd write it all out using algebra
The last inequality is true so the first inequality is true when n = 4. This is another way to see that n = 4 is a solution.
