Answer:
The mean number of cookies was 33.5
Step-by-step explanation:
Add the values of the terms and divide by the number of terms.
So...
26 + 38 + 45 + 25 = 134
134 ÷ 4 = 33.5

Answer:
54
Step-by-step explanation:
BEDMAS
z=10
(10)3-3(2-10)
=(10)3-3(-8)
=30-(-24) *2 negatives = a positive
=30+24
=54
For each part A through D below, the idea is to find the common factor between the terms, which you'll then use the distributive property to pull out.
==================================
Part A
3x + 18 = 3(x+6)
Note how we pulled out a 3. If we distribute it back in, we end up with 3x+18 again. The other problems are done in a similar fashion
==================================
Part B
2x - 14 = 2(x - 7)
==================================
Part C
6x + 4 = 2(3x + 2)
==================================
Part D
9x - 15 = 3(3x - 5)
