Answer:
x = 6
Step-by-step explanation:
To solve the value of x
3(x-2)=12
First solve the brackets
3x -6 = 12
Now Transpose
3x = 12 + 6
3x = 18
x = 18 ÷ 3
x = 6
The value of x will be 6
Can anyone help me with this? i dont need a graph i just need the answer for it
i need the original slope and parallel slope
Answer:
Slope is -2/3
Parallel slope is the same just draw another line with the same slope but a different y-intercept

A 3 fl oz bottle of orange juice costs $21 and a 6 fl oz. bottle of orange juice
costs $36. Which is a better buy?
Answer:
6floz bottle of orange juice.
Step-by-step explanation:
21*2=42
$42 for 6floz of juice vs $36 for the same amount. 36 is the better deal!
Answer:
6 fl oz. bottle of orange juice
Step-by-step explanation:
For the 6 fl oz bottle to be equal to the 3fl oz bottle prize, it would need to cost 42, but since it only costs 36$, it would be the better deal.

A tire shop had to fill 2 1/2 tires with air. It took a small air pump 2 1/2 seconds to fill them up. How long will it take to fill 8 tires?
Answer:
8 seconds if tyres took 1 second each tyre as 2.5/2.5 =1
The question did specify 2 1/2 secs to fll them all up which is 1 second each x 8 = 8 sec total.
Step-by-step explanation:
2 1/2 litres = number of tyres
2 1/2 seconds taken
= if each tyre took 2 1/2 seconds the quetsion should say clear but would be
2 1/2 tyres x 2 1/2 seconds = 6.26 seconds every 2 1/2 tyres
so 8 tyres x 2 1/2 seconds = 20 seconds every 8 tyres
If the 2 1/2 seconds applied to all 2 1/2
then we need to find a multiplier for 1 tyre
Here we divide
2 1/2 / 2 1/2 = 1
8 x 1 = 8 seconds.
Solve: ƒ(x) = 2x(x + 1)(3x − 1)

What is the solution to the system of linear equations? 2x + 3y = 3 3x + 5y = 5 Enter you answer into the boxes.
Answer:
x = 0
y = 1
Step-by-step explanation:
2x + 3y = 3 Multiply this equation by 3
3x + 5y = 5 Multiply this equation by 2
3(2x + 3y = 3)
6x + 9y = 9
2(3x + 5y = 5 )
6x + 10y = 10 Notice the xs are the same.
6x + 9y = 9
6x + 10y =10 Subtract
- y = - 1 Multiply each side by -1
y = 1
2x + 3y = 3
2x + 3*1 = 3
2x = 0
x =0

- 8/9x - 4/45x + 1/5x = - 70
Answer:
x = 90
Step-by-step explanation:
- [tex]\frac{8}{9}[/tex] x - [tex]\frac{4}{45}[/tex] x + [tex]\frac{1}{5}[/tex] x = - 70
Multiply through by 45 ( the LCM of 9, 45, 5 ) to clear the fractions
- 40x - 4x + 9x = - 3150 , that is
- 35x = - 3150 ( divide both sides by - 35 )
x = 90

8-x/10=11
please help me
Answer:
x = -102
Step-by-step explanation:
Step 1: Multiply both sides by 10.
[tex]\frac{8-x}{10} * 10 = 11*10[/tex] [tex]8-x = 110[/tex] [tex]-x + 8 = 110[/tex]Step 2: Subtract 8 from both sides.
[tex]-x + 8 - 8 = 110 - 8[/tex] [tex]-x = 102[/tex]Step 3: Divide both sides by -1.
[tex]\frac{-x}{-1} = \frac{102}{-1}[/tex] [tex]x=-102[/tex]Step 4: Check if solution is correct.
[tex]\frac{8-(-102)}{10} = 11[/tex] [tex]\frac{8+102}{10}=11[/tex] [tex]\frac{110}{10}=11[/tex] [tex]11 = 11[/tex]Therefore, x = 11.
Have a lovely rest of your day/night.
can you plz find this witj equation
In a high school basketball game, a player on the home team makes two free throws. One student asks the student next to her what he thinks the probability of hitting two free throws in a row is. The student replies, "The probability of him making a free throw is probably about .6, so hitting two free throws is probably about 1.2." Why can this immediately be dismissed as incorrect?
A.
The final number, 1.2, is a fraction, which can never represent a probability.
B.
The probability of making a free throw can never be .6.
C.
The probability of an event happening twice in a row can never be equal.
D.
The final number is greater than 1, which is not a valid probability.
Answer:
DStep-by-step explanation:
The probability can be expressed as a number between 0 and 1 or a percent value between zero and 100%.
Correct choice is:
D. The final number is greater than 1, which is not a valid probability.what values represent the sum of 1/2 + 3/12

I will only give brainliest if you do 14-23
I see you need help with 14 - 23 evens, so hopefully this is what you need. If not, comment and I will edit it as appropriate :) Have a nice day
14: It is slightly hard to see, but I am going to say 15 mm. We can decide this because the ruler says it is in mm and on both sides are 10 and 20. It is in the middle so we will decide the answer is 15.
16: 3,629 - 429 = 3,198 (not much explanation, just use a calculator or do the subtractation)
18: 491 * 700 = 343,700 (multiply 491 * 7, then add the two zeros onto the end of the answer because it's 700, not 7)
20: 5n = 3,175 ; n = 635 (divide both sides of the equation by 5)
22: See pictured below
After that, 2/3 is equal to 0.66666666666, which we can round to 67%
Even though it is not an even, you said "14 - 23" so here is 23 as well:
230, 240, 250, 260, 270, etc
/\
256 is inbetween here
It is above 5, so the answer is C 260

[2(5 – 4) + 6(7 – 3)] ÷ 2
Answer:
13
Step-by-step explanation:
Use PEMDAS
1. 5-4=1
7-3=4
Now you have the equation: (2x1 + 6x4)/2
2. 2x1=2
6x4=24
Now you have the equation (2+24)/2
3. 2+24= 26
4. 26/2=13
So your answer is 13.
Make sense?
Answer:
13
Step-by-step explanation:
2(5 – 4) = 2
6(7 – 3) = 24
2 + 24 = 26
26 ÷ 2 = 13
Hope this helps!

Hello there!
The right prime factorization is
2*2*2*3*11 because 2 and 3 and 11 are prime.
Take a look at the words "prime" and "factorization"
Can you see something that looks like "prime factors?" Exactly!
2 is prime. 3 is prime. 11 is also prime.
A prime number is only divisible by 1 and itself.
