Answer:
16 cookies
Explanation:
If each box has 32 cookies then, 4•32=128
Then if Leslie divides them equally into 8 platters, 128/8 will equal 16.
Answer:
x = -27, v = 8, n = -20.
Step-by-step explanation:
-45 - x = -18
+45 +45
-x = 27
/-1 /-1
x = -27
v - 55 = -43
+ 55 +55
v = 12
-2 = n/10
*10 *10
-20 = n
Answer:
-45
Step-by-step explanation:
Let the number be represented by x.
The question can be solved as x/9 + 8 = 3
This is because the quotient of the number and 9 is same as (x/9)
and it is expected to be eight more (+ 8)
Therefore, x/9 = 3 - 8
x/9 = -5
x = -5 x 9
x = -45
