Answer:
I think it would be 55+8x. I hope this helps. :)
Step-by-step explanation:
55 gallons of water
8 gallons per minute
It would be 55 gallons (the original amount in the tank) plus 8 gallons per minute. (8x)
x = how many minutes the tank is being filled up more.
so if you were to fill up the tank another 5 minutes, the equation would be 55+8(5)
55+40
95 would be the answer.
Answer:
The answer is B
Step-by-step explanation:
1)
These are in Y = MX + B form
The first line has a positive slope, so the coefficient "M" is positive.
The second line has a negative slope, so the coefficient "M" is negative.
2)
The first line has a filled in dot at Y = 2.
Since it's to the left (less than X direction)...
X <= 0
The second has an empty circle at Y = 4.
Since the line goes to the right....
0 < X
3)
Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.
From these things, we can infer that B is the correct answer.
Answer:
2,000 miles
Step-by-step explanation:
We are given:
This can be rewritten as:
This is representative of a unit rate, as we have a 
in the denominator. To calculate the number of miles in 
inches, simply multiply the unit rate by :
This can rewritten as:
Therefore, there are 2,000 miles in 4 inches.
-
We can check our solution by simplifying the fraction by dividing both 
and by to see if we achieve the unit rate:
Since this is in fact the unit rate, our solution is correct!
the answer is B because it is 90° to the left (i guessed, srry for takin ya points dawg)
Answer:
RS = 20
ST = 40
Step-by-step explanation:
R____S____T
RS + ST = RT
3x - 16 + 4x - 8 = 60
3x + 4x - 16 - 8 = 60
7x - 24 = 60
+24 +24
--------------------------------
7x = 84
/7 /7
---------------------------------
x = 12
Let's use what we got for x to find the length of ST and RS
ST = 4x - 8
= 4(12) - 8
= 48 - 8
ST = 40
RS = 3x - 16
= 3(12) - 16
= 36 - 16
RS = 20
so, RS = 20, ST = 40, and RT = 60
