Answer:
there would have been 12 crackers on the plate at the start
Step-by-step explanation:
So 1/3 +1/4 = 7/12
Therefore 5/12 left on the plate …ie 5.
So total to start with
5/5×12=12
Ans 12
-7 + 4(n-1). Use this and plug in 10 for n, making it
-7 + 4(9)
-7+36
29
2.5
3 1/2 - 9 3/4 =
3 2/4 - 9 3/4 = -6 1/4
-6 1/4 = -6.25 ÷ (-2.5) = 2.5
<u>With parentheses:</u>
(3 - 4)(4 + 5)/3
<u>Without parentheses:</u>
7 + 6 - 11 × 2
Hope this helps! :)
