Answer:
1) 144 seconds
2) 12
3) 24
Step-by-step explanation:
1) First off how many times can 15 dived into 90? 6! So we know it <em>can</em> go into 90 and that it's by 6. Next is to add 24 (seconds) 6 times. This will lead you too 144. So 144 seconds is your awnser
2) All you have to do is dived 72÷6. Which gives you the amount of each pack .
3) You take the total of step number two and 288 earsers and dived. so 288÷12=24

Answer:
a) f(-1) = 1
b) f(0) = 6
c) f(2) = 8
Step-by-step explanation:
If x is lesser than 0, we have that:
f(x) = 4x + 5
Otherwhise
f(x) = x + 6
(a) f(-1)
Here x = -1.
-1 is lesser than 0
Then
f(x) = 4x + 5
f(-1) = 4*(-1) + 5 = -4 + 5 = 1
(b) f(0)
Here x = 0
When x equals 0
f(x) = x + 6
Then
f(0) = 0 + 6 = 6
(c) f(2)
Here x = 2
When x = 2
f(x) = x + 6
Then
f(2) = 2 + 6 = 8
Answer:
To find the value of this expression you need to add and subtract from left to right
74.9+5.23-81.4-16 (add the first two, first)
80.13-81.4-16 (74.9+5.23=80.13) (next subtract the next two)
-1.27-16 (80.13-81.4=-1.27) (Last subtract the last two)
-17.27 (-1.27-16=-17.27)
-17.27
Hope this helps ;)
5(2+4m)=-2(5-10m)
10+20m=-10+20m
20m-20m=-10-10
m=-20
