Answer:
a is mark me as brainlist pls
Step-by-step explanation:
When 36 people are seated the room is 2/3 full.
So for 1/3 , 18 people are needed
It will be 3/3 full if 54 people are present
So there can be 54 people in total
Now for the room to be 1/2 full , people will be 1/2 x 54 = 27 people
Answer:
B
Step-by-step explanation:
-3 < 2x + 3 <= 5
-6 < 2x <= 2
-3 < x <= 1
such a condition is an "and" condition. both parts need to be fulfilled.
-3 < x and x <= 1
if you are still not seeing it :
-3 < x is the same as x > -3
now you see that B is the right answer.
x > -3 and x <= 1
for the first part:
Let's solve for x.
−x+3y=14
Step 1: Add -3y to both sides.
−x+3y+−3y=14+−3y
−x=−3y+14
Step 2: Divide both sides by -1.
−x/−1 = −3y+14/−1
x=3y−14
Answer:
x=3y−14
Second part:Let's solve for x.
3x−3y=−6
Step 1: Add 3y to both sides.
3x−3y+3y=−6+3y
3x=3y−6
Step 2: Divide both sides by 3.
3x/3= 3y−6/3x=y−2
Answer:
x=y−2
