Answer:

The value of x that makes the equation true is -50/7

Step-by-step explanation:

-12 - 2(x+9) =5(x+4)

-12 - 2x - 18 =5x + 20

- 2x -12-18 = 5x + 20

-2x - 30 =5x + 20

-2x - 5x = 20+ 30

-7x = 50

x = 50/-7

x = -50/7

Joe tracked the height of his Dalmatian puppy from age 13 weeks to 25 weeks. He graphed the data and determined the line of best

nadya68 [22]

Answer:

22.5 weeks

Step-by-step explanation:

y = 1.12x + 28.78 represents the height of the puppy. Here that height is 54 cm:

Then 54 = y = 1.12x + 28.78

Combining the constants, we get 1.12x = 25.22. Dividing both sides by 1.12, x turns out to be 22.5 weeks.

The number of seats in each row of a theater forms an arithmetic sequence. The fifth row contains 22 seats. The tenth row contai

beks73 [17]

Let $s_n$ denote the number of seats in the $n$ -th row. $s_n$ is arithmetic, so

$s_n=s_{n-1}+d$

for some constant $d$ .

We're told $s_5=22$ and $s_{10}=37$ , so that

$s_{10}=s_9+d$

$s_{10}=(s_8+d)+d=s_8+2d$

$s_{10}=(s_7+d)+2d=s_7+3d$

and so on up to

$s_{10}=s_5+5d\implies37=22+5d\implies5d=15\implies d=3$

The pattern continues:

$s_5=s_4+3$

$s_5=(s_3+3)+3=s_3+2\cdot3$

and so on up to

$s_5=s_1+4\cdot3\implies22=s_1+12\implies\boxed{s_1=10}$
