50 children had a choice of beans,plantain and rice.21 of them took beans,24 took plantain and 18 took rice.3 took beans only an
faltersainse [42]

The Venn diagram to illustrate this information is given in the image attached.

<h3>What is the Venn diagram about?</h3>

The number of children who took plantain and beans only are:

Let  beans = a

Rice = b

Plantain = P

So:  a + b = 24 - 9 - 5 = 10

Note that 24 children took plantain.

9 children took only Plantain.

5 took the 3 food items.

So:

b + c = 18 -2 - 5 = 11

a + c = 21 - 3 - 5 = 13

P∩B = a + 5

= 6 + 5 = 11

R ∩ B = C + 5

=7 + 5 = 12

None of the three items of food =  

50 - (3 + 2 + 9 + 6 + 4 + 7 + 5)

= 50 - 36

=14

Given F = 9 5 C + 32, the conversion formula for Fahrenheit to Celsius, solve for C.
Oksanka [162]
Since you are not given any values to plug in, solving for c simple means to isolate c. First, you would subtract 32 from both sides to get F-32=9/5C. Then, you would multiply both sides by 5/9 in order to get 5/9(F-32)=C or 5/9F-160/9=C.

Hope this helps.
