Use the following pattern to answer the questions. 24.3, 24, 23.7, 23.4, ___,____. part A. ( what is the rule for the pattern?

vodka [1.7K]

Question 1:

For this case we have the following pattern of numbers:

24.3, 24, 23.7, 23.4

It can be seen that subtracting 0.3 from the first number of the pattern gives $24.3-0.3 = 24\\$

Equally if we subtract 0.3 successively we obtain:

$24-0.3 = 23.7\\\\23.7-0.3 = 23.4\\\\23.4-0.3 = 23.1\\\\23.1-0.3 = 22.8\\$

Thus, 0.3 must be subtracted from each term and the following numbers of the pattern shall be 23.1 and 22.8

Answer:

subtract 0.3 from each term

The next two numbers of the pattern are 23.1 and 22.8

Question 2:

For this case we have the following operation:

$0.52 + 0.61 = 1.13\\\\1.13> 1\\$

We note that the sum is greater than 1

The sum of two hundredth decimals does not necessarily have to be greater than 1.

Therefore, the correct option is: the sum is greater than 1 because the sum shades more than one hundredths grid.

Answer:

Option C

Question 3:

For this case we have to:

$a + b + c = 2\\$

Being a, b, c decimal numbers, one of them was 0.34. Suppose $a = 0.34\\$

Thus: $0.34 + b + c = 2\\$

We choose values for b and c, in order to obtain the number 2 as a result of the sum. We can choose infinite values so that equality is fulfilled

If $b = 0.96$ and

$c = 0.7\\$

we have: $0.34 + 0.96 + 0.7 = 2\\$

Thus, Holland can add to the sum $b = 0.96$ and $c = 0.7\\$

Answer:

$b = 0.96\\\\c = 0.7\\$

Question 4:

For this case we have the following subtraction:

$3.5 - 2.46 = 1.16\\$

This operation is wrong, subtracting $3.5-2.46$ results in 1.04

Let's explain a model for Maysa:

We have the following expression

$3.5 - 2.46\\$

Rewriting each number in expanded form we have:

$(3 + 0.5) - (2 + 0.46)\\$

Using the distributive property we have:

$(3 + 0.5) -2-0.46\\$

Using the associative property we have:

$(3-2) + (0.5-0.46)\\$

Performing each operation:

$1 + 0.04 = 1.04\\$

Anwer:

The subtraction of Maysa is wrong, the correct answer is:

$3.5 - 2.46 = 1.04$

Jing jing works in a store and she spends some of her time organizing the stationary section. If there are nine different items

Alexus [3.1K]

Answer:

282240 ways

Step-by-step explanation:

number of items = 9 different items

Ranking based on worth

determine number of ways to arrange the 9 items such that the 2 most expensive are apart

first step: consider the 2expensive items as 1

∴ number of permutation = [ ( 9 - 2 ) + 1 ]! * 2!

= [ 8 ] ! * 2! = 80640

Total number of permutation/arrangement = 9! = 362880

hence to arrange the 9 items without having the two most expensive items together

= 362,880 - 80640

= 282240 ways

How would I solve a system of linear equations x+y=2, 2x+7y=9 by using elimination

Ad libitum [116K]

Answer:

x = 1 & y = 1, so (1, 1)

Step-by-step explanation:

Hello! Here is my explanation:

First, you need to set the equations like this:

x + y = 2

2x + 7y = 9

Since you are using elimination, we need to cancel out one variable, either x or y. Let's cancel out x, since that is an easier one to work with since the 2nd equation has a 2 as x's coefficient, whereas there is a 7 as y's coefficient. To cancel out x, we need to multiply the 1st equation by 2, including the "= 2", so that it can be the same as the x in the 2nd equation. Like this:

2(x + y = 2)

2x + 7y = 9

Then, distribute the 2 to the whole equation. Multiply that 2 to the x, the y, and the 2 after that "=" sign, like this:

2x + 2y = 4

2x + 7y = 9

Now we are ready to eliminate! Since we now have the same x and coefficients for both equations, we can cancel them out. To do so, we need to subtract both equations. When we do that, we get 0 as a result for only the x, leaving us with only the y to solve. So we do 2x - 2x (which will be 0, so no need to write that 0), 2y - 7y, and 4 - 9. Like this:

2x + 2y = 4

- 2x + 7y = 9

-------------------

-5y = -5

Next, we solve for y by dividing -5 on both sides, which will result in 1 being our y-value:

-5y = -5

-5 -5

y = 1

Now that we have our y-value of 1, we can plug that in for y in either one of our system of equations. It is always best and easiest to use the simplest equation with smaller numbers, so let's use the 1st equation, x + y = 2.

x + y = 2

x + 1 = 2

Now solve for x by subtracting 1 on both sides, which will result in 1 being out x-value:

x + 1 = 2

- 1 -1

x = 1

So therefore, the solution to this system of equations is (1, 1). We used the method of elimination to solve this system. I hope this helps you understand how to approach these problems! Have a great day :)
