If you reverse the first two letters
Na
Fe
Hg
Sn
They are actually symbols for elements
Na - Sodium
Fe - Iron
Hg - Mercury
Sn - Tin
Since Sn is a symbol for Tin and each pair of letters imply the starting letter of the element they are symbolizing, the answer is
1) T<span />
Adwoa sold x amount of bread during that week, where a is mathematically given as
x = 2700
This is further explained below.
<h3>What is a commission?</h3>
Generally, a payment made to a representative or employee in exchange for the completion of a transaction or the provision of a service, in particular: a predetermined share of the profits made from the whole sum, which is then distributed to the agent in charge of the company.
i) 20% × x = 540
Therefore
x = 540 × 100/20
x = 2700
In conclusion, During that particular week, Adwoa had a total sales volume of x, where x is denoted by the mathematical expression 2700.

Answer:
Step-by-step explanation:
We are given that Twice the difference of a number and 2 is equal to three times the sum of the number and 4. And we have to tell the number.
Let the number be x
Its difference from 2 = x-2
Twice the difference =2(x-2)
Sum of number and 4 = x+4
Three times of the sum : 3(x+4)
Hence 2(x+2)=3(x+4)
2x+2×2=3x+3×4
2x+4=3x+12
Subtracting 12 and 2x from both sides.
4-12=3x-2x
-8=x
Hence the number is -8
Answer:
It is a 50% chance that both cookies are sugar cookies.
Step-by-step explanation:
It takes one pipe x minutes, the other pipe x+3 minutes
the portion filled per minute is by one pipe is 1/x, by the second pipe 1/(x+3)
when two pipes running together:
3&1/3[1/x+1/(x+3)] =1, 1 means the whole cistern
solve for x: 3&1/3(x+3) +3 1/3(x)=x(x+3)
6 &2/3 x +10 =x^2+3x
x^2- (3&2/3) x-10=0
3x^2-11x-30=0
this cannot be factored, so use the quadratic equation:
x is about 5.5
x+3=8.5
