I believe the answer is 185
Answer:
the number before the first variable (first term)
Step-by-step explanation:
this appears to be an incomplete question. The numerical coefficient of a term is the number before the variable.
the constant is the number without a variable.
Varies directly basically means a multiple of
y = kx
where "k" is the constant of variation. You must solve for this first using the given information.
8 = 42k
8/42 = k
0.19= k
Equation: y = 0.19x
when x = 126
y = 0.19(126)
y = 24
To start this, id recommend just calculating each tank at different time intervals to see which is filling faster.
Let's start at 2 minutes since it's an even number for both scenarios.
Tank A: 3/4 gallon every 2/3 minutes. So for each 2/3 of a minute, we get 3/4 of liquid. So how many 2/3 of a minute are in 2 minutes? The answer is 3 because 2 minutes is the same as 6/3 minutes and 2/3 minutes goes into 6/3 minutes 3 times. So in 2 minutes you get 3 units of the rate. so That's 3/4 + 3/4 +3/4 = 9/4 = 2 1/4 gallons in two minutes.
Tank B: 5/8 gallon per 1/2 a minute. So after 2 minutes we will have 4 units of the rate: 5/8+5/8+5/8+5/8 = 20/8 = 2 4/8= 2 1/2
Since 2 1/2 is more, the second rate is filling faster.
Answer:
n=11.5
Step-by-step explanation:
n+6/-4=10
<em>6 divided by -4=-1.5</em>
n-1.5=10
<em>add 1.5 to both sides</em>
n=11.5
Hope this helped you!
