If it is 41/3, then the answer would be 13 and 2/3. If it is 4/13, then there would be no mixed number. Sorry. It is hard to tell because there is no slash to represent where the numerator and the denominator is.
Answer:
3.7

Answer:
Interest earned is $25.2
Step-by-step explanation:
The formula to find simple interest is:
I = P₀rt
Where
I = interest rate
P₀ = Principal amount
r = interest rate
t= time
5 months = 5/12 years = 0.42 years
I = 1000* 6/100*0.42
I = 1000*0.06*0.42
I = 60*0.42
I = 25.2
Interest earned is $25.2
Answer:
AC = AB + BC
18 = (2X - 4) + (3X + 2)
18 = 5X - 2 ( add/subtract like terms)
20 = 5X (-2 take over otherside - 18 + 2)
X = 4
SUB X INTO AB AND BC
AB = 2(4) - 4 = 4
BC = 3(4) + 2 = 14
Let the cost of 1 notebook be x and the cost of 1 binder be y.
4 notebooks and 3 binders would cost 23.5
Therefore, 4x + 3y = 23.5 (1)
7 notebooks and 6 binders would cost 44.5
Therefore, 7x + 6y = 44.5 (2)
Multiply the first equation by 2.
8x + 6y = 47 (3)
(3) - (2) gives
x = 2.5
Substitute the value of x in (1), we get,
4(2.5) + 3y = 23.5
10 + 3y = 23.5
3y = 23.5 - 10
3y = 13.5
y = 13.5/3
y = 4.5
Hence, cost of 5 notebooks and 3 binders is:
5x + 3y = 5(2.5) + 3(4.5)
= 12.5 + 13.5
= 26
Hence, cost of 5 notebooks and 3 binders is $26.
