Answer:

7 +1/5x ≥ 10 +1/10x . . . . . lower left picture of those shown here

Step-by-step explanation:

Caroline's hair length in inches can be expressed as ...

c = 7 + 1/5x . . . . after x months

Trinity's hair length in inches can be expressed as ...

t = 10 + 1/10x . . . . after x months

When Caroline's hair is at least as long as Trinity's, we have ...

$c\ge t\\\\\boxed{7+\dfrac{1}{5}x\ge 10+\dfrac{1}{10}x}$

Marisol plans to make 9 mini-sandwiches for every 2 people attending her party. Write a ratio that is equivalent to marisol's ra

DedPeter [7]

A ratio is not multiplication, so I'm just going to throw that out there first in case any other answers trip you up.

9:2 is the correct answer because there are 9 sandwiches for 2 people.

Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

<h3>How to calculate greater mean number of pages?</h3>

From the complete information, we can deduce that the number of each pile of book is given as follows:

Red books = 10 × 5 = 50 red books.

Blue books = 5 × 5 = 25 blue books.

Therefore, total books in pile W = 50 + 25 = 75 books.

Mathematically, the mean for each pile can be calculated by using the following formula:

Mean = [F(x)]/n

Mean = 75/10

Mean = 7.5.

Red books = 10 × 5 = 50 red books.

Mean = [F(x)]/n

Mean = 50/5

Mean = 10.

In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

System w/Elimination<br>-2x-9y=-25<br><br>-4x-9y=-25

Lerok [7]

x=0 and y= $\frac{25}{9}$

Step-by-step explanation:

We need to solve the system by elimination and find values of x and y

$-2x-9y=-25\,\,\,(1)\\-4x-9y=-25\,\,\,(2)$

Subtract eq(1) and eq(2)

$-2x-9y=-25\,\,\,(1)\\-4x-9y=-25\,\,\,(2)\\+\,\,\,+\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,+\\---------\\2x=0\\x=0$

Now Multiply equation (1) by 2 and subtract with eq(2)

$-4x-18y=-50\\-4x-9y=-25\\+\,\,\,\,\,\,+\,\,\,\,\,\,\,\,\,\,\,\,\,\,+\\--------\\-9y=-25\\y=\frac{-25}{-9}\\y=\frac{25}{9}$

So, x=0 and y= $\frac{25}{9}$
