Answer:
Step-by-step explanation:
Let C be the number of correct answers
Let B be the number of questions not answered
Let W be the wrong answers
Total = 2*C + B - W
It's a trinomial. There are three unrelated terms.
Answer: 1406

Now, the expected number of admissions for the fall semester is given by :-

Hence, the expected number of admissions for the fall semester = 1406
Answer:
y = -53/2, x = -17
Step-by-step explanation:
1/2x + 3/2 = -7
-3x +2y = -2
Isolate X for 1/2x + 3/2 = -7
X = -17
Substitute X = -17
-3(-17) + 2y = -2
Isolate Y for -3 (-17) + 2y = -2
Y = -53/2
You would need 18 3/4 quarts of sparkling water.
Answer:
$5: 7
$1: 10
Step-by-step explanation:
We can write the equation as such.
1. 5x + (x + 3) = 45
2. 6x = 42
3. x = 7
The number of $5 bills is 7, now we can use the x + 3 to solve the amount of $1 bills.
1. x + 3 = ?
2. 7 + 3 = 10
There are 10 $1 bills.
