Answer:
A. n = 2m -0.3
Step-by-step explanation:
The appropriate equation can be found by testing each at a couple of points in the table.
__
For m=0, the value of n will be the constant in each equation. The table tells you that must be -0.3. (Eliminates choices B and D.)
For m=2, the table tells you that n > m. (Eliminates choice C.)
The only viable choice is the correct one:
n = 2m -0.3
Yes, very fun, not
ok
one way is table or
solutions amount x and y
x+y=500
x=25%
y=50%
0.25x+0.5y=0.35(500)
we have
x+y=500
0.25x+0.5y=0.35(500)
0.25x+0.5y=175
solve
multiply second equation by 100
25x+50y=17500
divide everybody by 25
x+2y=700
now we have
x+y=500
x+2y=700
multiply first equation by -1 and add to second equaiton
-x-y=-500
<u>x+2y=700 +</u>
0x+1y=200
y=200
sub
x+y=500
x+200=500
x=300
300L of the 25% and 200L of the 50%
Answer:
the cat should be about 6 or 7 inches away
Step-by-step explanation:
I'm sorry if I was wrong I hope I help
1 + 1 = 2
That’s for your big test I guess, well GOOD LUCK
First let us calculate for the total time of the travel
using the formula:
time = distance / velocity
time = 90 miles / 40 mph
time = 2.25 hours
Next, we calculate for the total gallons of fuel that is
theoretically required:
theoretical amount needed = 90 miles / 24 mpg
theoretical amount needed = 3.75 gallons
The difference of the actual and theoretical amount is the
amount which leaked:
amount leaked = 8 gallons – 3.75 gallons
amount leaked = 4.25 gallons
Therefore the amount of gallons leaked per hour is:
amount leaked per hour = 4.25 gallons / 2.25 hours
<span>amount leaked per hour = 1.89 gallons / hr</span>
