What is this mixed numbers fraction 413

levacccp [35]

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.

Need help to write equations for 5, 6 & 7

hoa [83]

7)
Read my note at the end of problem 5 in another post.
You already know this table represents an exponential function
since each y-coordinate is always the previous y-coordinate multiplied by 6.
That means b = 6, and you have
y = a(6)^x
Now we find "a". When x = 0, y = 5. That means a = 5.
The equation is

y = 5(6)^x

25 pts and a mark for real answers. Help!! A store is having a sale on chocolate chips and walnuts. For 5 pounds of chocolate ch

kozerog [31]

Answer:

Each pound of chocolate chips costs $ 1.5 and each pound of walnuts cost $ 3.75 .

Step-by-step explanation:

Let, each pound of chocolate chips costs $ x and each pound of walnuts costs $ y.

Then, according to the question,

5x + 6y = 30 --------------(1) and,

3x + 2y = 12 ----------------(2)

Multiplying (2) by 3 we get,

9x + 6y = 36 ---------------------(3)

Deducting (1) from (3) we get,

4x = 6

⇒ x = 1.5 ----------------------(4)

From (4), putting the value of x in (2) , we get,

2y = 7.5

⇒ y = 3.75 ---------------------------(5)
