Because there's times when u need to double for instance a cup so u have to add one morecup
Answer:
1: 6
2: 20
3: 4
4: 2
Step-by-step explanation:
M + f = 15 . . . (1)
3m + 5f = 51 . . . (2)
(1) * (5) => 5m + 5f = 75 . . . (3)
(3) - (2) => 2m = 24
m = 24/2 = 12
Therefore, there are 12 multiple choice question on the test.
Step-by-step explanation:
The given equation is :
x = 6y ...(1)
Here,
x and y are variables and 6 is a constant number
It means,
x and y are related directly to each other i.e.
x ∝ y
or
x = ky .....(2)
Comparing equation (1) and (2)
k = 6
Hence, yes they are in direct proportion and the value of constant of proportionality is 6.
