ok
jim_thompson5910
  • jim_thompson5910
you have the correct equation set up
anonymous
  • anonymous
@jim_thompson5910 do you know?
anonymous
  • anonymous
oh...
anonymous
  • anonymous
So I am correct?
jim_thompson5910
  • jim_thompson5910
I'm guessing they want you to solve for b? or just set up the equation?
anonymous
  • anonymous
just setup
anonymous
  • anonymous
or basically put it in number form
jim_thompson5910
  • jim_thompson5910

The sum of 5 times h and twice g is equal to 23
anonymous
  • anonymous
5h+g^2=23
anonymous
  • anonymous
????
jim_thompson5910
  • jim_thompson5910
`twice g` means `2 times g`
jim_thompson5910
  • jim_thompson5910
so instead of g^2 you should have 2g
anonymous
  • anonymous
oh ok
jim_thompson5910
  • jim_thompson5910
g^2 means "g squared" g^2 = g*g
anonymous
  • anonymous
5h+2g=23?
anonymous
  • anonymous
is that right?
jim_thompson5910
  • jim_thompson5910
correct
anonymous
  • anonymous
ok....can u help with a couple more?
jim_thompson5910

One forth the sum of r and ten is identical to r minus 4
anonymous
  • anonymous
would you use a fraction for one forth...or literally use 1/4?
jim_thompson5910
  • jim_thompson5910
1/4 is a fraction, so yes
jim_thompson5910
  • jim_thompson5910
" the sum of r and ten" what does that translate to?
anonymous
  • anonymous
+++++
jim_thompson5910
  • jim_thompson5910
what do you mean?
anonymous
  • anonymous
Addition?
jim_thompson5910
  • jim_thompson5910
yes so " the sum of r and ten" means r+10, agreed?
anonymous
  • anonymous
Yes
anonymous
  • anonymous
so 1/4 (x or +) r+10
jim_thompson5910
  • jim_thompson5910
so 1/4 of that is simply \[\Large \frac{1}{4}(r+10)\]
jim_thompson5910
  • jim_thompson5910
1/4 times (r+10) or 1/4 * (r+10)
anonymous
  • anonymous
ok...
anonymous
  • anonymous
\[\frac{ 1 }{ 4} \times r+10=r-4\]
anonymous
  • anonymous
correct?
jim_thompson5910
  • jim_thompson5910
don't forget the parenthesis around the "r+10"
anonymous
  • anonymous
ohh ok
jim_thompson5910
  • jim_thompson5910
the 1/4 is being multiplied by ALL of "r+10" and not just the r
anonymous
  • anonymous
ok

what do you have for this one
anonymous
  • anonymous
K+C=273
anonymous
  • anonymous
idk
jim_thompson5910
  • jim_thompson5910
you have the equal sign in the wrong spot
jim_thompson5910
  • jim_thompson5910
have a closer look at the original sentence
anonymous
  • anonymous
k=273+c
jim_thompson5910
  • jim_thompson5910
correct
