Now off to a different topic in math

Estimate each expression . Use the order of operations when necessary.
anonymous
  • anonymous
a + 1, for = 10
cwrw238
  • cwrw238
10 + 1 = 11 (for a = 10)
anonymous
  • anonymous
okay , b - 3 , for b = 3
cwrw238
  • cwrw238
3-3 = 0

9 + c -5 , for c = 7
anonymous
  • anonymous
PLEASE HELP MelindaR
anonymous
  • anonymous
9 + c -5 , for c = 7
anonymous
  • anonymous
9 + 7 - 5 = ?
anonymous
  • anonymous
what's 9 + 7?
anonymous
  • anonymous
16
anonymous
  • anonymous
and 16 - 5?
anonymous
  • anonymous
11
anonymous
  • anonymous
there you go
anonymous
  • anonymous
So c equals to 11
anonymous
  • anonymous
guide me through the next one , okay
anonymous
  • anonymous
d * 8 , for d = 9
anonymous
  • anonymous
9 * 8 = ?
anonymous
  • anonymous
72
anonymous
  • anonymous
good
anonymous
  • anonymous
so the answer is 72?
anonymous
  • anonymous
yep
anonymous
  • anonymous
( e + 4 ) / 2 , for e = 8
anonymous
  • anonymous
( 8 + 4) / 2 = ?
anonymous
  • anonymous
6
anonymous
  • anonymous
yeah that's it
anonymous
  • anonymous
but, wait the question says e = 8
anonymous
  • anonymous
whats 6
anonymous
  • anonymous
( 6 + 4 ) / 2 , for e = 6 is that right?
anonymous
  • anonymous
( 8 + 4) / 2 = 6 because 8 + 4 is equal 12. and 12/2 is equal 6. got it?
anonymous
  • anonymous
yeah
anonymous
  • anonymous
okay , last question
anonymous
  • anonymous
5 + 8 * f , for f = 2
anonymous
  • anonymous
replace f for 2, can you do that?
anonymous
  • anonymous
i don't know
anonymous
  • anonymous
type the equation and instead of f you put 2
anonymous
  • anonymous
so , the expression would look like this 5 + 8 * 2 , for f = 2
anonymous
  • anonymous
yes, very good
anonymous
  • anonymous
now solve
anonymous
  • anonymous
first 8 * 2
anonymous
  • anonymous
16
anonymous
  • anonymous
then + 5 is 21
anonymous
  • anonymous
yeah correct
anonymous
  • anonymous
so , now the equation looks like ?
anonymous
  • anonymous
5 + 8 * f , for f = 2 5 + 8 * 2 5 + 16 21
anonymous
  • anonymous
thanks a lot
anonymous
  • anonymous
anytime
anonymous
  • anonymous
okay
