The product is 3 and 3 4ths (3 3/4)
Let's say he has 1 kg of each
2.25/kg and 3.75/kg
add together and divide by 2 to get average
6/2=3
so it must be a one to one ratio
25 kg/2=12.5 kg of each
12.5 of each brand
Answer:
x = 4
Step-by-step explanation:
y = kx²
NOTE: k is constant for proportionality
putting values for x and y
if x is 2
and y is 12
12 = k(2)²
12 = k4
12 = 4k
divide both sides by coefficient of k
12÷4 = 4k ÷ 4
k=3
substitute 3 for k
therefore when
y is 48
and k is constant 3
then x will be:
48=3x²
divide both sides by coefficient of x²
48 divide by 3 = 3x² divide by 3
16=x²
take the square root of both sides
√16 = √x²
x = 4
Answer:
1Step-by-step explanation:
1 + IS 1 AND ITS 1
<em>It would be $46 because when you add the 15% tax to it, the total is $61. </em>
<em>$61-15%=$46. To check $46+15%=61! Hope i helped! :-)</em>
