Can someone help me with this question!<br><br> 13-3/2 x =37
kaheart [24]

Answer:

13-3/2x=37

taking LCM,

13×2x/1×2x - 3/2x=37

26x-3 /2x=37

cross multiply

2x × 37=26x-3

74x=26x-3

74x-26x=-3

48x=-3

x=-3/48

x=-1/16

hope it helps you!

X represent the number of caramel popcorn bags and Y represents the number of cheddar popcorn. They earn $1 for every caramel ba
Rainbow [258]

Answer:

The correct option is;

30 caramel popcorn bags and 80 cheddar popcorn bags

Step-by-step explanation:

From the graph of the number cheddar popcorn, Y to the number of the caramel popcorn, X, the shaded region of the graph which is the feasible region has a solution at the value Y = 80 and X = 30 and another at the value Y = 40 and X = 90

Therefore, when the team makes 80 bags of cheddar popcorn and 30 bags of caramel popcorn, we have;

2.5 × 80 + 1 × 30 = $230

When the team makes 40 bags of cheddar popcorn and 90 bags of caramel popcorn, we have;

2.5 × 40 + 1 × 90 = $190

Therefore, the team should make 30 caramel popcorn bags and 80 cheddar popcorn bags.

X f(x)<br> 0 24<br> 1 12<br> 2 6<br> 3 3
LenaWriter [7]

The table represents an exponential function given by:

f(x) = 24*(1/2)^x

<h3>Is the function exponential or quadratic?</h3>

Here we have the table:

x    f(x)

0    24

1      12

2      6

3       3

First, notice that for each unit that x increases, the value of f(x) decreases by its half.

This is clearly an exponential equation, whose base must be equal to (1/2).

And because when x = 0, f(0) = 24, we know that the initial value of the function is 24.

Then the exponential function is:

f(x) = 24*(1/2)^x

Such that:

f(0) = 24*(1/2)^0 = 24\\\\f(1) = 24*(1/2)^1 = 12\\\\f(2) = 24*(1/2)^2 = 24*(1/4) = 6\\\\f(3) = 24*(1/2)^3 = 24*(1/8) = 3

Concluding, the table represents an exponential function.
