Answer and explanation:
Since x = number of true or false questions correct
And y = number of multiple choice questions correct
And each question for x =2 points
each question for y=3 points
since she then needs a total score of more than 93 to pass, we add up total correct questions and
Inequality equation = 2x +3y >93
True!
all parabolas with vertical directrix DO open to the left/right.
Step-by-step explanation:
3x + 2y = 9
- (3x + y = 6)
=> y = 3.
Therefore 3x + (3) = 6, 3x = 3, x = 1.
The solutions are x = 1 and y = 3.
Answer:
5/12.5 = 8/p
Step-by-step explanation:
There is 5 pictures in 12.5 hours
How many can he paint in 8 hours
8=HOURS
P=AMOUNT
2/7 - 5/21 = 6/21 - 5/21 (find common denominator first, then subtract)
6/21 - 5/21 = 1/21
3/4 = 63/84
5/7 = 60/84
7/12 = 49/84
63/84 + 60/84+ 49/84 = 172/84
172/84 - 4/84 = 168/84
The answer is 168/84, or 2. Hope this helped!
