What value of x is in the solution set of 8x 6 12+2x
O-1
O 0
O 3
O 5
Step-by-step explanation:
Just consider the inequalities an equal sign and do the usual way of solving:
8x - 6 > 12 + 2x
8x - 2x > 12 +6
6x > 18
x > 3
*The only rule that you need to remember is that when you multiply or divide a negative number on both sides, then the inequality sign would be reverse.*
Example:
-x + 3 > -2
-x > -2-3
-x > -5
Multiplying both sides by -1:
x < 5

Sanjay has 35 pens and Mohan has 40 pens. These two, along with four other friends, collect their pens together. If Sanjay takes back his pens, the average number of pens with the rest of them is 20. What will be the average number of pens with the rest of them, if Mohan also takes back his pens?
"First, you have 35 total pens in the box. 15 are green. to find how many red pens you need to find the difference between 35 and 15 to get how many red pens there are. (35-15= 20) Therefore, there are 20 red pens. The ratio needs to be green pens to red pens. So, there is 15 green and 20 red ( 15/20 or 15:20) Simplify that by 5 and you get 3/4 or 3:4. "

There is a series of three chemical reactions (1→2→3) that form the overall chemical reaction.
How is the ΔH3 calculated if the others are known?
ΔH3 = ΔH1 + ΔH2 - ΔH4
ΔH3 = ΔH4 -( ΔH1 + ΔH2)
ΔH3 = (ΔH1)(ΔH2)(ΔH4)
ΔH3 = ΔH1 + ΔH2 + ΔH4
From the statement of Hess law, the ΔH3 is calculated when others are known from; ΔH3 = ΔH4 -( ΔH1 + ΔH2).
What is Hess law?Hess law of constant heat summation states that the total heat evolved or absorbed for a series of reactions is the sum of all the heat absorbed or evolved at all steps in the reaction sequence.
Let the heat for the overall reaction be ΔH4 while ΔH1, ΔH2 and ΔH3 designate the heat of reaction for reactions 1,2,3. It then follows that, the ΔH3 is calculated when others are known from; ΔH3 = ΔH4 -( ΔH1 + ΔH2).

a bowl has 3 red jellybeans,4 green jellybeans and 2 pink jellybeans. what is the probabilty of not choosing a red jelly beans
Answer:
1/2
Step-by-step explanation:
4+2 is green and pink jelly beans. 6. 3 is red. 3/6 is the probability, which is 1/2
Answer:
Step-by-step explanation:
Total Number of Jelly Beans = 3 + 4 + 2 = 9
There are two ways to do this. You could just add the pink and green jellybeans and put that over the total to get the probability of not red.
Sometimes it is better to find the probability of getting red and subtracting it from 1.
P(red) = 3/9 = 1/3
P(not red) = 1 - 1/3
P(not red) = 2/3

The expression which is equivalent to the difference of the given algebraic fraction is,
[tex]\dfr\dfrac{(x+5)(x+2)}{x(x-3)(x+3)}[/tex]
What is the difference?Difference is the mathematical operation in which the one number is subtract from another number.
To find the difference of two fraction numbers, we find the least common factor of denominator and write the all numbers as one fraction.
The given expression in the problem is,
[tex]\dfrac{2x+5}{x^2-3x}-\dfrac{3x+5}{x^3-9x}-\dfrac{x+1}{x^2-9}[/tex]
Factorize the denominator of each term as,
[tex]\dfrac{2x+5}{x(x-3)}-\dfrac{3x+5}{x(x-3)(x+3)}-\dfrac{x+1}{(x-3)(x+3)}[/tex]
Here, the least common factor of the denominators is x(x-3)(x+3), therefore, the expression can be written as,
[tex]\dfrac{(x+3)(2x+5)-(3x+5)-(x)(x+1)}{x(x-3)(x+3)}\\\dfr\dfrac{2x^2+5x+6x+15-3x-5-x^2-x}{x(x-3)(x+3)}\\\dfr\dfrac{x^2+7x+10}{x(x-3)(x+3)}\\\dfr\dfrac{(x+5)(x+2)}{x(x-3)(x+3)}[/tex]
Hence, the expression which is equivalent to the difference of the given algebraic fraction is,

Answer:
c = 2
w = 18
x = 9
Step-by-step explanation:
When you have a power raised to a power, you multiply the exponents. If there are more than one term that are multiplied together, that exponent needs to go to both of the terms.
Also, if you have a negative exponent, you can change the sign of it by pushing that term across the fraction bar. see image.

Hey there!
Let's solve your equation step-by-step.
[tex]\fbox{2y−(8)(9)=(((−3)(9))(5))(y)+476}[/tex]
Step 1: Simplify both sides of the equation.
[tex]\fbox{2y−(8)(9)=(((−3)(9))(5))(y)+476}[/tex]
[tex]\fbox{2y+−72=−135y+476}[/tex]

if 4 friends eat 4 cakes in 4 days then how many cakes will 10 friends eat in 10 days
Answer:
If four friends can eat four cakes in four days, then four friends will eat an average of one cake per day, so each friend will be able to eat 1/4 of a cake per day.
So 10 friends will eat 10/4 of cake per day, or two and a half cakes per day, so they will eat 2,5 * 10 = 25 (twenty-five) cakes per 10 days, assuming they will eat at the same rate

if m∠TUV=(9x+11)°, m∠TUW=(7x-9)°, and m∠WUV=(5x-11)°, find the value of x.
Answer: X = 9
Step-by-step explanation:
We know that a triangle has 3 angles that add up to 180 degrees.
9x+ 11 + 7x - 9 + 5x - 11 = 180
21x - 9 = 180
21x = 189
x = 9
Laurie saw some stray cats in her backyard. She put out some water and a bowl with 3 cups of food. The cats drank all the water and ate half of the food. How many ounces of food did the cats eat?
Answer:
12
Step-by-step explanation:
1 cup = 8 ounces.
In total, there are 3 cups of food.
So, we do 3 × 8 which would equal 24.
24 ÷ 2 = 12.
12 is half of all the food Laurie gave to the stray cats
Therefore, 12 is the correct answer.
