Step-by-step explanation:

Answer:  x=2

Step-by-step explanation:

9(x+1)=25+x   (Distribute the 9)

9x+9=25+x     (Work both sides to isolate the variable)

-9        -9

9x=16+x

-x       -x

8x=16

/8   /8

x=2

Answer:

no solution

Step-by-step explanation:

20 < 5(F - 32) < -15

-15 can never be greater than 20, thus the answer is no solution

Answer:

option number 3

Step-by-step explanation:

Answer:

[tex]k=6[/tex]

Step-by-step explanation:

We can distribute the right side to get [tex]38+7k=8k+32[/tex].

We can subtract [tex]7k[/tex] from both sides to get [tex]38=k+32[/tex].

We can subtract [tex]32[/tex] from both sides to get [tex]6=k[/tex].

So, the answer is [tex]\boxed{k=6}[/tex] and we're done!

The solution to the equation 38 + 7k = 8(k + 4) is k = 6.

We can begin by simplifying both sides of the equation in order to find the solution to the equation 38 + 7k = 8(k + 4):

38 + 7k = 8k + 32

Next, we can separate the constant terms from the variable terms by placing them on opposite sides of the equation:

7k - 8k = 32 - 38

Simplifying even more

-k = -6

We can multiply both sides of the equation by -1 to remove the negative sign:

k = 6

Hence K = 6 is the answer to the equation 38 + 7k = 8(k + 4).

Answer:

1 1/2 gallons

Step-by-step explanation:

1/4 * 6 = 6/4 = 3/2

1/6+1/6+1/6+1/6+1/6+1/6 = 1 whole wall

that means it takes 6 times 1/4 gallon to finish the wall

Answer:

p = - 2 , q = - 1

Step-by-step explanation:

Rearrange the left side into standard form

- x² + 4x - 5

Factor out - 1 from - x² + 4x

= - (x² - 4x) - 5

Using the method of completing the square

add/subtract ( half the coefficient of the x- term)² tp x² - 4x

= - (x² + 2(- 2)x + 4 - 4) - 5

= - (x - 2)² - (- 4) - 5

= - (x - 2)² + 4 - 5

= - 1 - (x - 2)²

Comparing to q - (x + p)²

with p = - 2 and q = - 1

Answer:

It has 9 factors.

Step-by-step explanation:

The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. Therefore, if you count both 1 and 100, it has 9 factors.

Step-by-step explanation:

a ) 9 × 2 = 18 → 18 + 3 = 21

o/p = 21

b) 17 - 3 = 14 → 14/2 = 7

i/p = 7

Answer:

x>=-8 and a colored in point on negative eight with an arrow to the right

Step-by-step explanation:

-7x<=56 is the given

to solve, we would divide both sides by -7. However, when dividing an inequality, the direction of the inequality sign flips (if you've heard the alligator example, the mouth opens in the opposite direction it was before)

so we know have x>=-8

On the number line, the colored in dot represents that the value it is on is within the set, and since this can also be equal to -8 we have to use a colored in dot because its within the possible values. If it was not <= or >= then we would use an open circle to represent it cannot be that value but can be anything in the direction the arrow is pointing.

The arrow would point to the right because x can be larger or greater than -8 as well

Answer:

y = -5/3x + 19/3

Step-by-step explanation:

y2 - y1 / x2 - x1

-2 - 8 / 5 - (-1)

= -5/3

y = -5/3x + b

8 = -5/3(-1) + b

8 = 5/3 + b

19/3
