Answer:
A,C and E
Step-by-step explanation:
For every 3ml of vinegar we have 8ml of oil
This implies that
For case (A):
80ml of oil with 30ml of vinegar
dividing the amount of vinegar by 3 and multiplying the result by 8 gives 80 I.e
hence that's it

Answer:
2(2x-1)
Step-by-step explanation:
Answer:
Let the length of shorter piece be x ft.
so '' '' '' '' '' '' = 2 x + 3
A/Q, x + 2 x + 3 = 27
3 x = 24
x = 8
Length of shorter piece = x = 8 ft.
'' '' longer '' = 2 x + 3 = 16 +3 = 19 ft.
Step-by-step explanation:
let x and y be the length of the longer and the shorter pieces of the hose respectively.
By question,
x + y = 27 --- (1)
and,
x - 2y = 3 --- (2)
subtracting (1) by (2), we get,
y-(-2y) = 27-3
=> 3y = 24
=> y = 24/3
=> y = 8
putting y = 8 in (1)
x + 8 = 27
=> x = 27-8
=> x = 19
Therefore, the length of the shorter piece is 8 ft and the length of the longer piece is 19 ft
Answer:
the value of c is 25
Step-by-step explanation:
b/2a= 10/2(1)= 10/2= 5
(5)^2 = 25
x^2 + 10x + 25 = (x + 5)^2
