Answer:

$\frac{2}{7}$

Step-by-step explanation:

These questions required just careful reading of it.

first it is said April has $\frac{3}{7}$ of a pound, which means April has $\frac{3}{7}$ pounds of pecan.
Next it is said that April's sister ate $\frac{2}{3}$ of what April had, which means she ate $\frac{2}{3}$ of $\frac{3}{7}$ pounds of pecan which is nothing but $\frac{2}{3} \times \frac{3}{7}=\frac{2}{7}$ pounds of pecan.

You order plant seeds from a catalog. Each packet cost 0.90 each. The shipping charge is 2.50. If you have 18.50 to spend, how m

<h2>Answer:</h2>

<h2>Step-by-step explanation:</h2>

Cost per Packet * Number of Packets + Shipping = Amount to Spend

0.90 * b + 2.50 = A

You can spend a maximum of $18.50

A < 18.50

Rearrange the formula to find b

Number of Packets = Amount to Spend - Shipping / Cost per Packet

18.50 - 2.50 = 16.00 / 0.9 = 17.7...

You can't have 0.7 of a packet so you have to round down to 17.

Now if you put it into the original formula:

0.90 * 17 + 2.50 = 17.80

And 17.80 is less than 18.50.

$y+8 = \frac{1}{2}(x-7)$ is equivalent to <span> $y-(-8) = \frac{1}{2}(x-7)$

That is in the form </span><span> $y-y_{1} = m(x-x_{1})$ which is point slope form

In this case,

m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>

Answer:

The second choice

Step-by-step explanation:

So first we would plug in the first term which is 2 so we would get $an=2$ times $rn-1$ so next we would see that the common ration is -3 since every time the number is being multiplied by -3. so then our equation would be $an= 2$ times $-3n-1$ . Now we would just find the choice that matches and it would be the second choice.
