hw #2-3 and 2-4 Variables, Equations, Solutions, and MORE Variables!!??
I;m getting confused on number 45 page 107 i created a chart for the gym thing showing the prices and I guess hoping they would merge at one point but after 7 months it didnt look like I was going to get my answer soon whats an equation i can use to fugure out this problem?
i need help on number 21 on page 106
ReplyDeletewhat did you try as a first step (hint: how about distribution?)
ReplyDelete3(q-5)=2(q+5)
3q-15=2q+10
... can you hop on the algebra roller-coaster now??
oh i see now. i just tried to subtract the q when it was still in the parentheses

ReplyDeleteOne more question.srry! for number 46 how would I solve 2x+4 without there being a solution wouldnt the answer simply be 2x+4?
ReplyDeleteI'm having trouble with #24 pg 106. I don't know whether to distribute the- 3g or something else.
ReplyDeleteIn #46, if the perimeters are equal, then:
ReplyDelete(2x+4)+(2x+3)+2x=2x+2x+(3x+1)
Combine Like Terms
6x+7=7x+1
Sub 6x fbs
7=x+1
Sub 1 fbs
x=6
In #24:
(g+4) - 3g = 1+g
simplify CLT (3g is being subtracted!)
-2g+4=1+g
Add 2g tbs
4=1+3g
Sub 1 fbs
3g=3
g=1
