Answer:
B) n ≥ - 9 and n ≤ 1
Step-by-step explanation:
-3 <= n+6 <= 7
subtract 6 from all 3 sides
-3 -6 <= n+6 -6 <= 7-6
-9 <= n <= 1
Answer:
Part A: 2D + 3 = A
Note: I have likely given you the answer to the whole problem. See below.
Step-by-step explanation:
Givens
- Alan = A
- Bruce = B
- Cecil = C
- Dylan = D
Comment
You have to pay the most attention to Alan and Bruce. Once you have equations for those two. Cecil's weight is just the sum of those two.
<em>Alan</em>
Alan = Twice*Dylan + 3 or
A = 2*D + 3
<em>Bruce</em>
Bruce = three * Dylan - 12
B = 3*D - 12
<em>Cecil</em>
Cecil = Alan + Bruce
C = A + B
Note
The last equation shows you how to combine the first two.
C = A + B
A = 2D + 3
B = 3D - 12
C = 2D + 3 + 3D - 12
C = 5D - 9
Answer:
first two is 300, then it is Car A's speed is 50mph and b is 40mph and for the other two it is probably faster and steeper
Step-by-step explanation:
you look at the graph. you see 6 miles and look up along the 6 mile line to see where it intersects the red line. once you find that spot you go left along that line to find the answer. same with the other and it both ends up at 300
for the next two find the slope, which is 40 and 50
and for the next two there are multiple answers but i t is probably faster and steeper
Yes i could. The multiplication process will even be more simple since it only involve small number.
For Example:
1234
5
_______x
4 x 5 20
5 x 30 150
5 x 200 1000
5 x 1000 5000

Done done done, W=3.46+8.5
W=11.96!
