The direct variation equation that is satisfied by this ordered pair is y = 6/5x
In order to find this, we start with the base equation for direct variation. We then plug in and solve for k.
y = kx
6 = k5
6/5 = k
And now we can use that to model all future direct variations with this.
y = 6/5x

Mark and his friends Byron were watching a superhero movies. During the movie mark ate 5 pieces of candy . Byron ate 7 times as much candy as mark. How much candy did Byron eat.?
Final answer:
To find out how much candy Byron ate, we multiply the number of candies Mark ate, which is 5, by 7. Byron ate a total of 35 pieces of candy.
Explanation:
The question involves solving a basic multiplication problem to determine how much candy Byron ate if Mark ate 5 pieces of candy and Byron ate 7 times as much. According to the given scenario, we can represent this mathematically as:
Mark ate 5 pieces of candy. Byron ate 7 times as much candy as Mark did. To find out the total pieces of candy Byron ate, we multiply the number of candies Mark ate by 7. Therefore, Byron ate 5 pieces × 7 = 35 pieces of candy.
This arithmetic calculation shows us Byron's total candy consumption during the movie.

what is 0.012 as a fraction
To convert 0.012 to a fraction, you multiply by 1000 to get 12/1000 and then simplify it to 3/250. Therefore, 0.012 as a fraction is 3/250.
To convert the decimal 0.012 into a fraction, follow these simple steps:
Write down 0.012 as 0.012/1.
Multiply both the numerator and the denominator by 1000 to get rid of the decimal point:
0.012 x 1000 / 1 x 1000 = 12 / 1000.
Simplify the fraction by finding the greatest common divisor (GCD) of 12 and 1000, which is 4:
(12 ÷ 4) / (1000 ÷ 4) = 3 / 250.
Thus, 0.012 as a fraction is 3/250.

81x-27, apply the distributive property to factor our of the greatest common factor
The greatest common factor of the expression 81x - 27 is;
⇒ 27 (3x - 1)
What is Greatest common factors?
The highest number that divides exactly into two more numbers, is called Greatest common factors.
Given that;
The expression is;
⇒ 81x - 27
Now,
Solve the expression for the greatest common factor as;
Since, The greatest common factor of the numbers 81 and 27 = 27
So, We take common 27 as;
⇒ 81x - 27
= 3 × 3 × 3 × 3x - 3 × 3 × 3
= 3 × 3 × 3 (3x - 1)
= 27 (3x - 1)
Thus, The greatest common factor of the expression 81x - 27 is;
⇒ 27 (3x - 1)

You saw on the previous page that 2/11=0.18. Show how you can use what you know about the decimal for 2/11 to find the decimal for 1/11
1/11 is half of 2/11. (1/11 + 1/11 = 2/11)
As 2/11 = 0.18, 1/11 must equal half of 0.18.
Half of 0.18 is 0.09. Thus the decimal for 1/11 is 0.09.
Answer:
The decimal for 1/11 is 0.09
Step-by-step explanation:
We have two options to get the answer, the first one is when we know that 1/11 is half of 2/11, so 1/11 will be half of 0.18. We have to divide 0.18 by 2:
0.18÷2 = 0.09
The other way to do it is to divide 1÷11 = 1/11
The answer is 0.09

A garage door opener has a ten number keypad. Codes to open the door must consist of 5 digits with no adjecent digits the sane. How many codes are possible?
1st slot: 10 possibilities
2nd slot: 9 possibilities
3rd slot: 9 possibilities
4th slot: 9 possibilities
5th slot: 9 possibilities
10 * 9 * 9 * 9 * 9 = 65610 Possibilities
The total number of possible 5-digit codes for the garage door opener, where no two adjacent digits are the same, is 59,049.
Explanation:This is a combinatorics problem in mathematics. A simple way to solve this problem is to calculate the total number of 5-digit code combinations possible without any constraint, which is 10^5 = 100,000.
However, the condition given in the problem is that no two adjacent digits can be the same. The possible codes for the first digit are 10 (0-9). For the second digit, because it cannot be the same as the first, there are 9 possibilities, the third digit also has 9 possibilities because it cannot be the same as the second, and so on.
Therefore, the total number of possible codes is 10 * 9 * 9 * 9 * 9 = 59,049. Hence, the garage door opener can have 59,049 different codes.

Which expression can be used to find 80% of 120?
120*0.8 is the expression, because you can put 80% as 80/100 and that is equal to .8 so you just put that in a calculator and thats your answer. Hope that helped :)
Answer:
[tex](0.80)120[/tex]
Step-by-step explanation:
We are asked to find an expression that represents 80% of 120.
We know that % means per hundred. 80% would be 80 divided by 100.
[tex]80\%\text{ of }120=\frac{80}{100}\times 120=(0.80)120[/tex]
Therefore, the expression [tex](0.80)120[/tex] represent 80% of 120.

Answer: A
(1.)
|x| + 5 = 18
(2.)
|y + 4| < 1
(3.)
|2t| - 5 = 7
(4.)
|a| - 3/4 = - 5/8
Gotcha!
The 1st answer is x=-13 or x=13
The 2nd answer is -5<y<-3
The 3rd answer is t=-6 or t=6
The 4th answer is a=-1/8 or a=1/8
4. Solve the following inequality: 3y-1 less than 3
3y - 1 < 3
Isolate the y. Treat the less than or equal like an equal sign.
Do the opposite of PEMDAS. First, add 1 to both sides
3y - 1 (+1) < 3 (+1)
3y < 4
Next, divide 3 from both sides
3y/3 < 4/3
y < 4/3
y < 4/3 is your answer

A pizza eating participant can eat 3 slices ok pizza in 2 minutes if he continues at this rate then how many slices of pizza will he eat in 10 minutes
at this rate, he can eat 15 slices of pizza in 10 minutes **wow!!**
we can do this by setting it up as a proportion: 3slices/ 2 minutes= ?/1 minute
we divide 3 by 2 to get how many slices he can eat in one minute, which is 1.5
so, now, we just have to multiply 1.5 times 10 minutes, and we get 15 slices of pizza per 10 minutes

Hey there!!
Given equation :
... -4 ( x + 10 ) - 6 = -3 ( x - 2 )
Using the distributive property :
... -4x - 40 - 6 = -3x + 6
Combining like terms :
... -4x - 46 = -3x + 6
Adding 46 on both sides :
... -4x = -3x + 52
Adding 3x on both sides :
... -x = 52
... x = -52
