Answer:
The answer is below
Step-by-step explanation:
N is inversely proportional to t, therefore:
N ∝ 1/t
Let k be the constant of proportionality, hence we can replace the relationship by:
N = k/t
Given that when t is 36, N is 176. Therefore we can find the value of k:
176 = k / 36
k = 176 * 36 = 6336
N = 6336/t
Also let us find N when t = 6. This is done by substituting t = 6 into the equation and simplifying:
N = 6336/6
N = 1056
You would do 64 divided by 6. You would divide it by 6 because it’s himself AND 5 friends. This would get you to 60. So now each friend has ten. Their would be four left over. So now Nick had 14 cards for himself.
> multiply the second equation by 2 and add it to the first equation.
2(-6x - 7y = -10)
-12x -14y = -20
8x + 14y = 4
-12x - 14y = -20
--------------------
- 4x + 0 = - 16
x = -16/-4
x = 4
> use x = 4 in either equation to find y
8(4) + 14y = 4
32 + 14y = 4
14y = 4 - 32
14y = -28
y = -28/14
y = -2
Answer:
88 score.
Step-by-step explanation:
Given:
To get a B in math, Alexandria Pappas must<u> average 80</u> on five tests.
Scores on the first four tests were <em>82, 74, 82, and 74.</em>
Question asked:
What is the lowest score that she can get on the last test and still get a B?
Solution:
Let lowest score she can get on the last test = 
As we know:
By cross multiplication:-
Thus, she can get 88 score on the last test to get a B in math.
