Answer:
the answer is, {x,y} ={2,1}
Step-by-step explanation:
1) 4x - 3y = 5 2) x + 2y = 4 3) 4•(-2y+4) - 3y = 5 4) - 11y = -11 5) 11y = 11 y = 1 6) x = -2y+4 y = 1 7) x = -2(1)+4 = 2 = {x,y} = {2,1} !!!

What is the value of the expression 3x+9 if x=6
Answer:
27
Step-by-step explanation:
3(6)=18
18+9=27
Answer:
27
Step-by-step explanation:
You would use PEMDAS to solve this equation, P (parenthesis) E (exponates) M (multiply) D (divide) A (add) S (subtract). The way you use this is by following the steps in the order that you would spell PEMDAS, so 3x+9 would be 3•6+9. So look at the equation 3•6+9, so what would we use first? do we have parenthesis? No, Do we have exponents? No, Do we have multiplication? Yes, so multiply 3 and 6 = 18. Now the equation will look like this 18+9 = 27.
Hope this helps!

if lana bought cigarettes for $3.00/pack X 7 packs/week X 52 weeks/year X 10 years, how much would it be?
EASY QUESTION OF THE DAY (whoever answers first gets brainly!)
Answer:
she would be spening over a thousand dollars
Step-by-step explanation:
Asnwer:
10,920$
Step-by-step explanation:
So if 3.00$ is for one pack and she wants 7 packs then it would be 21$.
But if we also multiply it by 52 weeks then that would be 1,092$.
Then if she's buying that for 10 years then we multiply 10 x 1,092$ which would equal 10,920$
(I'm not completely sure if I did the math right but I'm 90% sure I did because that's what the question is asking.)
What is the value of 9 2/3 minus 4 1/5
Answer:
5 7/15 = D
Step-by-step explanation:
Find a common denominator multiply the many times you did to the denominator to the numerator then subtract.
15 is your common denominator so I would multiply 5 to 2 to get 9 10/15 then I would multiply 3 to 1 to get 4 3/15
Answer:
5 7/15
Step-by-step explanation:
Let's solve your equation step by step.
We will solve it in just 3 simple steps.
Step 1: Converting into Improper Fraction.
Converting into an Improper Fraction is the only way to subtract fractions.
We will turn 9 2/3 into 29/3
First you need to know:
What is a numerator?
What is a denominator?
What is a whole number?
If you know, you can skip this part.
A denominator is the lower number below the line in a fraction. (ex. 2/3 <-- "3" is the denominator)
A numerator is the higher number above the line in a fraction. (ex. 2/3 <---"2" is the numerator)
A whole number is a number that has no fraction or decimal. (ex. "3" or "2" or "7".)
With that said, let's solve.
In 9 2/3, "9" is the whole number. "2" is the numerator, and "3" is the denominator.
We always multiply the whole number by the denominator, then we add the numerator.
So:
(9 x 3) + 2 = 29
Then, we keep the denominator the same. "3".
We then get:
29/3. Which is what we want.
Let's repeat the same steps with 4 1/5.
(4 x 5) + 1 = 21
Keep the denominator : 21/5
Now we are on Step 2.
We currently have 29/3 - 21/5
But we don't have the denominators the same.
We need to find the LCD (Least Common Denominator of 3 and 5.
Since these numbers are less than 10, my trick is to just multiply them together. 3 x 5 = 15, simply put.
Now, let's change all the denominators to 15. Now let's change the numerators.
For the fraction that had 3 as the denominator, let's multiply 5 to it. And for the fraction that had 5 as the denominator, let's multiply 3 to it.
We then get :
145/15 - 63/15
We are now on Step 3.
This step is simple. Just subtract 145 - 63 because the denominators are the same.
145 - 63 = 82
We now have 82/15.
This is the answer, but we always need to simplify it.
How many times can 15 fit into 82? 5. But we have 7 left over.
So we now have :
5 7/15

Four friends shared 7 chocolate bars. Each of them was given an equal share of the chocolate bars. How many chocolate bars did each person get?
A: 4/7
B : 6/8
C: 1 1/4
D: 1 3/4
We are given:
There were 7 chocolate bars, evenly shared between 4 friends
Number of Bars one person will get:
Number of bars one person will get = Number of Bars / Number of Friends
Number of Bars = 7 / 4
but since this number does NOT match any of the given options, we will convert it to a mixed fraction
The number of bars one person will get will be [tex]1\frac{3}{4}[/tex], written as a mixed fraction.
Therefore, the correct answer is option D
Answer:
4 friends =7 chocolate
1 friend =7/4 chocolate =1 3/4 part of chocolate.
Ryan is studying. The number of minutes he has studied varies directly with the number of calories he has burned. See the
graph below.
How many minutes does ryan study per calorie burned?
What is the slope of this graph?
Answer:
0.1 minute per calorie burned. Slope is up 0.1 , right 1. or 0.1/1
Step-by-step explanation:
You find a point such as (10,100) or (20,200) then you divide the number of minutes by calorie burned to get minutes per calorie burned.

you would want to make the 3/10 eqale to 20/100 like it has to have the same denominatior which is 10x10 and 3x10. because 10x10 eqal to 100, and what you do to the bottom you have to do the same on the top. and then you add which becomes 30/100+20/100=50/100 and 50/100 =1/2 if you simplfiy.

how do i write the difference of a number x and 2 is 7 as an equation
You can quiet literally write the question as it is.
The difference of a number x and 2 is 7.
The difference of a number x and 2 can be written as x-2
is can be written as equal or =
This statement can be translated as x-2=7.
It is as simple as that!

Answer:
Option B871.5 feetStep-by-step explanation:
Q1
∠PTQ + ∠QTS = ∠PTS, angle addition postulate
∠PTS is a straight line, therefore equals to 180°
Correct choice is:
B. The angles add to 180°Q2
1 inch → 83 feet ⇒10.5 inches → 10.5*83 feet = 871.5 feetHOWDY;)
1.Option B
2.871.5 feet
Q 1
PTQ + QTS =PTS,angle addition postulate
PTS is a straight line,therefore equals to 180°
Correct choce is:
B angles add to 180Q2
1 inch > 83 feet >
10.5 inches > 10.5*83 feet = 871.5 feet
