B. Subtraction.
C. Multiplication.
D. Division.
Please make an explanation to this. . .
Answers
Answer:
The first step is A. Subtraction
The second steep is D. Division
Step-by-step explanation:
The first step was done in other to remove the constant at one end of the equality that was with the variable, it was done in order to eradicate the constant and isolate the variable to make the equation easier to solve.
The second step was done in order to remove the coefficient of the variable so as the variable to be on it's own as x alone.
These two steps were just followed in order to find the value of the variable.
Answer:
The first step is to combine the constant terms by using the (B.) subtraction property of equality.
The second step is to use the (D.) division property of equality to isolate the variable.

6(9 + 5x) = 54 +
Answers
Hi
to progress in math, you must : know by heart the rules and formulas then train.
rule : a ( b+c ) = a*b + a*c.
this propertie is call distributivity .
so we have : 6 ( 9+5X)
here : a = 6
b = 9
c = 5X
so 6 ( 9+5X) = ?
I let you have a shot. Ask in comments section if you are stuck. But try first !
Answer:
1) rearrange terms:
6(9 + 5x) = 54
6(5x + 9) = 54
2) Distribution :
6(5x + 9) = 54
30x + 54= 54
3) subtract 54 from both side:
30x + 54 = 54
30x + 54 - 54 = 54 - 54
4) Simplify: subtract the numbers
30x = 0
5) Divide both side of the equation by the same term:
30x = 0
30x√30 = 0√30
6) Simplify: cancel term that are in the both numerator and denominator
x = O√30
solution :
x = 0]

Select all ratios equivalent to 2:3.
Answers
Answer:
12:18 and 10:12 (i think)
Step-by-step explanation:
After converting the given ratios in their simplest form, the equivalent form of 2:3 we get 12:18.
To find the simplest form of a fraction, you have to simplify the numerator and denominator to their lowest terms and keep dividing until you can no longer simplify the fraction any further.
The given ratios are,
12:18,
3:21,
10:12
For the ratio 12:18,
Simplify it by finding the greatest common divisor (GCD) of 12 and 18.
The GCD of 12 and 18 is 6.
By dividing both numbers by 6, we get the smallest ratio of 2:3.
Moving to the ratio of 3:21,
Find the GCD of 3 and 21, which is 3.
Dividing both numbers by 3 results in the smallest ratio of 1:7.
Find the smallest ratio for 10:12.
The GCD of 10 and 12 is 2.
Dividing both numbers by 2 gives us the smallest ratio of 5:6.
Hence, the simplest form of ratios for the given ratios are:
12:18 = 2:3,
3:21 = 1:7,
10:12 = 5:6.
Hence,
The ratio equivalent to 2:3 is 12:18.

Find the number that makes the ratio equivalent to 1:5.

1:5 is the same as 1/5.
So, the question really is 1/5 = 6/what?
6/30 is the same as 1/5
So the missing number is 30.
Answer:
box = 30
Step-by-step explanation:
You could set this up very formally as a proportion. It would look like this.
1/5 = 6/x
Now all you have to do is cross multiiply.
1*x = 5 * 6
x = 30
So the answer that goes in the box is 30
Or you could just say to yourself. "The 1 was multiplied by 6. What do I have to multiply the 5 by to keep the ratio the same?"
The answer is 6
6 * 5 = 30

Max makes three piles of cards, each consisting of only a Queen and a Jack. Lisa draws one card from each pile. What is the probability that Lisa draws two Queen and a Jack in any order? Make a tree diagram of all the choices
Answers
Answer:
3/8
Step-by-step explanation:
The probability of picking either a Queen or a Jack from each pile is always 1/2 (as there are only 2 cards).
There are only 3 ways in which Lisa can draw two Queens and a Jack:
Queen, Queen, Jack
Queen, Jack, Queen
Jack, Queen, Queen
The probability of each one happening is 1/8
This is because there is a 1/2 chance of picking a Queen or a Jack from each pile and to calculate the probability that Lisa will pick a Queen AND a Queen AND then a Jack (for example) you multiply the probabilities together:
1/2 x 1/2 x 1/2 = 1/8
This is the same for other examples and since there are only 3 ways that Lisa can draw two Queens and a Jack you multiply 1/8 by 3 (you add 1/8 together 3 times) to get 3/8
It can be represented on a tree diagram however I am not sure how I can show images/drawings on this
