Answer:

x = 3

y = -1

Step-by-step explanation:

in this system, we are given that y = x - 4

this means that we can take the other equation and replace y with x - 4:

so 2x - 3y=9 turns into

2x -3 (x - 4) = 9

distribute -3 to x and -4:

2x - 3x + 12 = 9

add like terms and subtract 12 from both sides

-x = -3

divide both sides by -1 to get rid of the negative on x:

x = 3

now we have the value of x, so we can replace the x in y = x - 4 with the value we just got

so y = x- 4 turns into

y = (3) - 4

solve and you get

y = -1

Using the rise over run strategy, you can get this answer by...

1. Look at the line and graph 2 points. ( 1 , 1 ) & ( 2 , 2 ).

2. Do the rise over run thing. ( how am I going to get from 1 point to the other.)

You get to it by rising 1 and running 1. The pattern is self explanatory.

3. Divide rise over run and the quotient is your answer

1 divided by 1 is 1.

Answer:

$15.12

Step-by-step explanation:

{10 * 0.08 = 0.8

4 * 0.08 = 0.32} (Brackets are here so you can see what I did easier and so you could see how to do it mentally.)

[0.8 + 0.32 = 1.12]

14 + 1.12 = 15.12

David is buying a cheese wheel priced at $14 on 8% sales tax.

David's pays for the cheese wheel is $15.12 .

Given:

Before-tax, the price of cheese wheel = $ 14

Sales tax on cheese wheel = 8%

Sales tax is 8% of $14

[tex]=\frac{8(14)}{100} = \frac{112}{100} = 1.12[/tex]

So, the sales tax on the cheese wheel is $1.12

The total price of the cheese wheel, including tax = $ 14 +  $1.12 = $15.12

Therefore, David's pays for the cheese wheel is $15.12 .

Answer: $8.50/pound

Step-by-step explanation:

Price per pound --> take the total price and divide it by the number of pounds

$22.10 / 2.6 pounds = $8.50/pound

Answer:

$8.50

Step-by-step explanation:

take 22.10 divide it by 2.6 and you will get your answer.

Answer:

A: C=45h+30

B: C=$322.50

Step-by-step explanation:

A: We'll start with the equation for the total charge. Juan is saying he will pay a one time fee of $30, meaning there is 30 dollars added to what ever the hourly wage is. This can be represented by the +30. Now if "h" represents the variable for which the hourly wage will be calculated, and he pays $45 dollars per hour this will be represented as 45h. As an example if I pay you 2 dollars per hour using the same variable "h", this would be represented as 2h. So if you worked for two hours you would get 4 dollars, this is proven by the fact the 2(2) (remeber im replacing the "h" with the hours you worked) obviously 2 times 2 is 4 proving my point. This information will give you the equation you see above.

B: Onto solving for how much Juan will pay. Now you say youre supposed to have 9 answer but this can't be true. All you need to do is plug the hours given into "h" and solve the equation. It should look something like:

C=45h+30

C=45(6.5)+30

Im using a decimal because it should be clear 1/2=0.5

C= 292.5+30

45x6.5 always go with PEMDAS, we are multiplying first. Then add 292.5 plus 30

This results in the answer of:

C=$322.50

Answer:

0.43* 0.35 = 0.1505 or 0.15 after rounding

Step-by-step explanation:

Based on the probabilities of A and B occurring with conditions, the probability of A and B occurring is 0.15.

This can be found by the formula:

= Probability that A occurs if B occurs x Probability of B occurring if A occurs

Solving gives:

= 0.43 x 0.35

= 0.15

In conclusion, the probability is 0.15.

Answer:

The 2nd option.

Step-by-step explanation:

Since  Angle D is 68 degrees side EF would be the longest.

Side DF is the shortest side it is opposite the smallest angle.

Side EF is in the middle since opposite the next biggest angle.

Side EF is again the longest since Angle D is the biggest at 68 degrees.

Hi there!

[tex]\large\boxed{x = 8}[/tex]

Recall that all angles in a triangle sum up to 180°, therefore:

(9x + 3) + (5x - 2) + (11x - 21) = 180

Combine like terms:

9x + 5x + 11x + 3 - 2 - 21 = 180

25x -20 = 180

Add 20 to both sides:

25x = 200

Divide both sides by 25:

x = 8°

Answer:

Step-by-step explanation:

we know that the sum of the angles in a triangle is 180

(5x-2)+(9x+3)+(11x-21)=180

=5x-2+9x+3+11x-21=180

25x=180+20

25x=200
