Answer:
x = z - m
Step-by-step explanation:
<u>Solving for x with steps:</u>
- z=m+x
- x + m = z
- x + m - m = z - m
- x = z - m
1. Yes
2. No
3. 46.6 (recurring)
5. 22'
Sorry this is all I can do. Hope this helps :)
Answer:
22
Step-by-step explanation:
if a=15
then, 2(a-5)+2= 2(15-5)+2 = 2(10)+2= 20+2=22
3x + 5 + 4x =180
7x + 5 = 180
7x = 175
x = 25
3(25) + 5
75 + 5
80
KL = 80
METHOD 1
f(3) = 20
f(4) = 30
f(5) = 42
f(6) = 56
rate of change
f(4)-f(3)=10
f(5)-f(4)=12
f(6)-f(5)=14
then the average of change is 10+12+14 /3 = 12
METHOD 2 --- faster
rate of change = f(6)-f(3) / 6-3
= (36+18+2)-(9+9+2) / 3
= 36/3 = 12
