The answer is 2m because it is like if you had 3 mangoes and you eat one you would have 2 mangoes.<span />
Answer:
x = 5 , y = 15
Step-by-step explanation:
You can solve this using substitution.
Let the quantity of cheese wafers be denoted by x and the quantity of chocolate wafers denoted by y
2x + 1y = 25
x + y = 20
These two equations are the answer to part A, (remember to include the above prompt which says what x and y denote).
For part B I used substitution because it was more applicable to the question then addition or elimination.
ACTUAL WORK
Set 2x + 1y = 25 equal to x
x = 25 - y / 2
Replace x with y in the second equation
(25 - y / 2) + y = 20
And solve for y
y = 15
Since we know what y is we can replace y in the second equation and find what x is
x + 15 = 20
Solve for x
x = 5
Volume = length * height * width
= 4 qrt3 + 3 sqrt6 * w
= 12 sqrt18 w
let w = 2 sqrt50 then volume = 2*12 * sqrt 18*50 = 24*30 so this is rational
let w = 4 sqt 12 the v = 48 sqrt12 * sqrt 18 = 48 sqrt30 which is irrational
C and D are rational
answer is B
