In order to solve the system of equations
{x-3y=2
{2x+y=11
Using the elimination method, which of the following steps could be used?

Answers

Answer:

Multiply the second equation by 3 and then add result to the first equation

Step-by-step explanation:

Given the equations :

x-3y=2

{2x+y=11

To solve by elimination :

Multiply one of either equations by a number to give a result such that adding the result to the other equation in the system leads to the removal of one of the unknown values.

By Multiplying the second equation by 3 and then add result to the first equation

Second equation becomes :

6x + 3y = 33

Adding the result to the first equation :

x - 3y = 2

6x + 3y = 33

___________

7x = 35

Solve the proportion for k: 5/3 = ( k + 7 )/12

Answers

Answer: k = 13

5/3 = (k + 7)/12

⇔ 12.5/3 = k + 7

⇔ 20 = k + 7

⇔ k = 20 - 7

⇔ k = 13

Step-by-step explanation:

Answer:

k = 13

Step-by-step explanation:

To get k by itself, multiply both sides by 12 (left with 20 = k + 7). Next, subtract 7 from both sides (13 = k).

5 cards are drawn at random from a standard deck. Find the probability that all cards are face cards.

Answers

Answer:

99 / 324,870 or 3%

Step-by-step explanation:

there are 12 face cards out of a total of 52 cards

probability of 5 face cards = [tex]\frac{12}{52}[/tex] · [tex]\frac{11}{51}[/tex] · [tex]\frac{10}{50}[/tex] · [tex]\frac{9}{49}[/tex] · [tex]\frac{8}{48}[/tex]

The probability that all cards are face cards at the time when 5 cards are drawn at random from a standard deck should be [tex]99 / 324,870[/tex]

Calculation of the probability:

Since 5 cards are drawn at random from a standard deck

Also, we know that

there are 12 face cards out of a total of 52 cards

So here the probability be like

[tex]= 12/52 \times 11/51 \times 10/50 \times 9/49 \times 8/48[/tex]

= [tex]99 / 324,870[/tex]

Hence, The probability that all cards are face cards at the time when 5 cards are drawn at random from a standard deck should be [tex]99 / 324,870[/tex]

solve for x -2x + 2 = x -13

Answers

Answer:

x = 5

Step-by-step explanation:

Add 2x to both sides: 2 = 3x - 13

Add 13 to each side: 15 = 3x

Divide both sides by 3: 5 = x

Isolate with the variable by dividing each side by factors that don't contain the variable. So, x= 15

1. The sum of six times a number, and 1, is equal to five times
the number. Find the number.

Answers

Answer:

-1

Step-by-step explanation:

To solve this word problem, we need to convert it into an equation. Let's first dissect the problem:

"The sum of six times a number and 1" -- since "sum" means addition, and "6 times" means 6 multiplied by some number, we can write this as: 6x + 1, where x stands for the unknown number

"is equal to five times the number" -- since "equals" means "=" and five times the number means 5x, where x stands for that same unknown number, we can write as: = 5x

Put it all together and we have

6x + 1 = 5x

Now we can solve our equation.

First, we need to get all of the like terms on each side of the equal sign. To do this, we will first subtract 1 from both sides:

6x + 1 - 1 = 5x - 1, which gives us 6x = 5x - 1

Next, we will subtract 5x from both sides:

6x - 5x = 5x - 5x - 1, giving us x = -1

-1 is the number

hope this helps

Answer:

x=-1

Step-by-step explanation:

6 x + 1 = 5 x

6 x - 5 x + 1 = 5 x - 5x

x +1 =0

x+1-1=-1

x=-1

HELP PLS ASAP PLS

Answers

Answer:       43 is the answer.

Step-by-step explanation:

43 because 45 + 43 is the only number that could equal 88 and the total that tom earned.

Answer:

(see below)

Step-by-step explanation:

First, assess your info:

- total of $88

- $45 for dog walking

- $b for babysitting

Now, use that info to write an equation to combine all of this info:

$45 + $b = $88

If you were to find b, however, you'll need to simplify:

$45 + $b = $88

$b = $88 - $45

b = $43

isabella collected a bunch of dimes and quarters for her school fundraiser she collected a total of 211 coins and a total of 37.30 how many dimes and how many quarters did she collect

Answers

Answer:

103 dimes and 108 quarters

Step-by-step explanation:

Given

[tex]Value = \$37.30[/tex]

[tex]Amount = 211[/tex]

Required

Determine the number of each coin collected

Represent dimes with D and quarters with Q.

[tex]1\ D= \$0.10[/tex]

[tex]1\ Q= \$0.25[/tex]

So:

[tex]0.10D + 0.25Q = 37.30[/tex] --- Value

[tex]D + Q = 211[/tex] --- Amount

Make D the subject in [tex]D + Q = 211[/tex]

[tex]D = 211 - Q[/tex]

Substitute 211 - Q for D in [tex]0.10D + 0.25Q = 37.30[/tex]

[tex]0.10(211 - Q) + 0.25Q = 37.30[/tex]

Open brackets

[tex]21.1 - 0.10Q + 0.25Q = 37.30[/tex]

Collect Like Terms

[tex]- 0.10Q + 0.25Q = 37.30 - 21.1[/tex]

[tex]0.15Q = 16.2[/tex]

Make Q the subject

[tex]Q = 16.2/0.15[/tex]

[tex]Q = 108[/tex]

Substitute 108 for Q in [tex]D = 211 - Q[/tex]

[tex]D = 211 - 108[/tex]

[tex]D = 103[/tex]

Answers

Answer:

Option B

Step-by-step explanation:

In this question , we just need to make "F" as the subject of the equation.

So, lets solve the equation.

[tex]R = \frac{F}{N + F}[/tex]

→ Multiplying (N + F) on both the sides ,

[tex]=> R \times (N + F) = \frac{F}{(N + F)} \times (N + F)[/tex]

[tex]=> RN + RF = F[/tex]

→ Substracting both the sides with RF ,

[tex]=> RN + RF - RF = F - RF[/tex]

[tex]=> RN = F - RF[/tex]

→ Taking F common from R.H.S ,

[tex]=> RN = F(1 - R)[/tex]

→ Dividing both the sides by (1 - R) ,

[tex]=> \frac{RN}{1 - R} = \frac{F(1 - R)}{(1 - R)}[/tex]

[tex]=> \frac{RN}{1 - R} = F[/tex]

∴ Hence , [tex]F = \frac{RN}{1 - R}[/tex]
