Let’s start with the travoprost boxes! she needed 15 travoprost boxes! But, you only have 10 travoprost boxes, which means you need 5 more, to have all 15 boxes in which you need! Now you need 12 latanoprost boxes! But you only have 3! So, you need 9 more latanoprost boxes to have the full 12 boxes you need! So, now you need to order 9 latanoprost boxes, and 5 travoprost boxes! Do you get it now?

Answer:

A = 5

B = 9

Step-by-step explanation:

This was very simple!

Nancy needs at least 15 boxes of travoprost but she only has 10. To find out how many she needs, we subtract 15 from 10 to get 5 boxes

Nancy also needs at least 12 boxes of latanoprost but she only has 3. To find out how many she needs, we subtract 12 from 3 to get 9 boxes

Therefore A = 5 boxes; B = 9 boxes

How do I solve it because it’s really difficult

dybincka [34]

The solution of the equation is x= 3 and y = 2

Step-by-step explanation:

Given,

-3x-4y = -17 and

-x-3y = -9

The system of equation can be rewritten as

3x+4y = 17 ------eq 1 and

x+3y = 9 ------ eq 2

To solve for x and y

Multiplying eq 2 by 3 we get,

3x + 9y = 27

or, 3x = 27-9y

Putting this value of x into eq 1 we get,

27-9y +4y = 17

or, -5y = 17-27

or, -5y = -10

or, y = 2

Now put y=2 in eq 2 we get,

x = 9 - 3(2)

= 3

Hence the solution is x = 3 and y = 2

What are the solutions to the equation?

Maru [420]

rearrange the equation to where you set it equal to 0 by moving the 25 over.

n2 - 8n -9 = 0

now factor

(n-9)(n+1)

so n1 = 9

n2 = -1

Algebraic Reasoning please help!

stiv31 [10]

Answer:

$\left[\begin{array}{ccc}7\\4\\2\end{array}\right]$

The answer is a single-column matrix (7,4,2)

Step-by-step explanation:

In such multiplication of matrices, you have to proceed by multiplying each ROW of the first matrix by the COLUMN of the second matrix. So,

$\left[\begin{array}{ccc}3&6&1\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (3 * 2) + (6 * 0) + (1 * 1) = 6 + 0 + 1 = 7$

then...

$\left[\begin{array}{ccc}2&4&0\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (2 * 2) + (4 * 0) + (0 * 1) = 4 + 0 + 0 = 4$

and

$\left[\begin{array}{ccc}0&6&2\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (0 * 2) + (6 * 0) + (2 * 1) = 0 + 0 + 2= 2$

I hope it helps.
