Answer:
4 students
Step-by-step explanation:
As shown in the diagram, let U=[The total number of students questioned]
A=[Those who liked peanut butter ]

We add x and subtract 30 to both sides.
Therefore 4 students like both peanut butter and jam.
The volume of the cylinder in discuss in which case, the radius of the cylinder is 3 inches and the height is inches is; V = 141.3in³.
<h3>What is the volume of the the described cylinder?</h3>
The cylinder in discuss according to the task content has radius, 3 inches and height, 5 inches.
Since the volume of a cylinder by convention is given as; V = πr²h
Therefore, the volume of the cylinder in discuss is;
V = π (3²)×5
V = 3.14 × 45
V = 141.3in³

28% = 28/100 = 0.28
$100.80/0.28 = $360 ← answer
X and x+ 2 equal 188
add all the like terms to get 2x+2=188
subtract 2 from each side
2x=186
divide by 2
x=93
so the numbers are 93 and 95
