Answer:

Answer c) (13)

Step-by-step explanation:

Begin with 3x+2x-45=20. Go through the steps of solving this for x.

Combining like terms, we get 5x = 65.

Dividing both sides by 5, we get x = 13.

Answer c) (13) is the correct answer/solution/root.

Greg made 9 gallons of chili for a chili dinner. Each bowl can hold 2 full ladles of chili. A full ladle holds 10 ounces. What i

Katarina [22]

The answer is A
There are 128 ounces in a gallon.
So multiply that by 9 to get 1152 ounces in 9 gallons.
Divide that by ten because each ladle is 10 ounces.
Divide that by 2 since there are two ladle scoops in each bowl.
You get 57.6 which you can't have a .6 bowl so it is just 57

Simplify √(x^2-10x+25) if -5≤x<5

romanna [79]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's simplify ~

$\qquad \sf \dashrightarrow \: \sqrt{ {x}^{2} - 10x + 25 }$

$\qquad \sf \dashrightarrow \: \sqrt{ {x}^{2} - 5x - 5x + 25 }$

$\qquad \sf \dashrightarrow \: \sqrt{ {x}^{} (x- 5) - 5(x - 5) }$

$\qquad \sf \dashrightarrow \: \sqrt{ (x- 5) (x - 5) }$

$\qquad \sf \dashrightarrow \: \sqrt{ (x- 5) {}^{2} }$

$\qquad \sf \dashrightarrow \: (x- 5)$

value x lies between :

$\qquad \sf \dashrightarrow \: - 5 \leqslant x \leqslant 5$

if the value of x is taken -5

$\qquad \sf \dashrightarrow \: - 5 - 5$

$\qquad \sf \dashrightarrow \: - 10$

if value of x is taken as 5

$\qquad \sf \dashrightarrow \:5 - 5$

$\qquad \sf \dashrightarrow \:0$

So, the possible values of the required expression lies between ~

$\qquad \sf \dashrightarrow \: - 10 \leqslant \sqrt{ {x}^{2} - 10x + 25 } < 0$

I hope you understood the whole procedure. let me know if you have any doubts in given steps ~

Solve for x 9x-3-8x=7-x

Kipish [7]

Answer:

x = 5

Step-by-step explanation:

First, we move all variables to one side of the equation. (Don't forget to change signs.)

9x - 8x + x = 7 + 3

Then, we simplify

x + x = 10

2x = 10

10 divided by 2 is equal to 5.

Therefore, x = 5

Hope this helps!
