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 ]
B=[Those who liked jam ]
x = those who like both peanut butter and jam.
Also 6 liked neither peanut butter nor jam.
From the diagram we can write the mathematical equation as follow and solve for x
We add x and subtract 30 to both sides.
Therefore 4 students like both peanut butter and jam.

Answer: </h3>
Step-by-step explanation:
Its true because 4/3 = 16/12
correspond ing sides are in the same ratio
1500 points= 100%
x =68%
(68)(1500)/100= 1020
He must have 68%(1020points) of the 1500 points
He has 953 points
1020-953= 67
He must earn 67 more points by the end of the term
Hey there, Faithfuljoshua!
It's already given that the perimeter is 12 meters.
The length of the rectangle is 3 times more than it's width.
To do this, we can use an equation. Let's use the variable x
So, 3x + x = 12
3x being the length
x being the width
Now we solve for x
3x + x = 12
4x = 12 (Now we divide both sides by 4)
x = 3
Now, we have to replace the x values for 3
So, the length is 3x changes to 3(3) = 9 meters
And the width is x being 3 meters.
