x is -4 and y is 15

$3x + y = 3 \\ 2x + y = 7 \\ \\ 3x + y = 3 \\ - 2x - y = - 7$

$x = - 4 \\ \\ y = 12 + 3 \\ y =15$

A box contains 10 tags, numbered 1 through 10, with a different number on each tag. A second box contains

Tju [1.3M]

Answer:

(E) 29.0

Step-by-step explanation:

If a tag is drawn at random from each box, the expected value of the sum of the tags is the sum of the expected values for each tag.

The expected value for each tag is the mean value of the numbers in its box.

$EV = \frac{1+2+3+4+5+6+7+8+9+10}{10} +\frac{20+21+22+23+24+25+26+27}{8} \\EV = 5.5 +23.5\\EV= 29$

The expected value of the sum of the numbers on the two selected tags is 29.

$\boxed{(6, -3)}$

Step-by-step explanation:

Given the ratio 5:3

and Points A and B where A is located at (-6, 3), and B is located at (26, -13).

Let point A be $(x_{1}, y_{1})$ , and let point B be $(x_{2}, y_{2})$ .

(-6, 3) → $(x_{1}, y_{1})$ .

(26, -13) → $(x_{2}, y_{2})$ .

Let 5 be n, and 3 be m.

5:3 → n:m

$(\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m})$ .

To solve, just substitute these variables into the expressions of these coordinates to get the answer.

$(\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m})$ →

$(\frac{(5)x_{1} + (3)x_{2}}{(5)+(3)}, \frac{(5)y_{1} + (3)y_{2}}{(5) + (3)})$ →

$(\frac{(5)(-6)+ (3)(26)}{(5)+(3)}, \frac{(5)(3)+ (3)(-13)}{(5) + (3)})$ →

$(\frac{-30 + 78}{8}, \frac{15+ -39}{8})$ →

$(\frac{78 – 30}{8}, \frac{15 – 39}{8})$ →

$(\frac{48}{8}, \frac{-24}{8})$

→

$(\frac{6}{1}, \frac{-3}{1})$

→

$(6, -3)$ .

Thus the coordinates of B are:

$\boxed{(6, -3)}$

Cerrena [4.2K]

I think you left out the word half. I am going to assume you meant half. If half the garden is planted with flowers, then you take away half of the area, which would be 36. that leaves you with 36sq.ft. that he has used to plant vegetables
