Answer:
The solution of the system of equations is (-8,3).
Step-by-step explanation:
Given that:
3x + y = -21 Eqn 1
x + y = -5 Eqn 2
First of all, we will subtract Eqn 2 from Eqn 1
(3x+y)-(x+y)=-21-(-5)
3x+y-x-y=-21+5
2x=-16
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{-16}{2}[/tex]
x=-8
Putting the value x=-8 in Eqn 2
-8+y= -5
Adding 8 on both sides
-8+8+y= -5+8
y=3
Hence,
The solution of the system of equations is (-8,3).

Is y=12 x+3 a proportional relationship
Answer:
no
Step-by-step explanation:
A proportional relationship is of the form
y = kx
This is equation is of the form
y = kx+b
They are not the same so it is not a proportional relationship
Which problems can be solved by performing this multiplication? 23×18 Select each correct answer. Sarah mixed 18 ounces of orange juice with 23 ounce of pineapple juice.

Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes? Min had 18 quarters. He used 23 of the quarters to play arcade games. How many quarters did Min use?
Answer:
Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?
Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?
Step-by-step explanation:
2/3 × 18
Checking all options
Sarah mixed 18 ounces of orange juice with 23 ounce of pineapple juice. How many ounces of juice did she have in all?
Ounces of orange juice = 18
Ounces of pineapple juice = 23
Total ounces of juice = 18 + 23
= 41 ounces
A container held 18 ounces of water. Two-thirds of the water leaked out of the container. How many ounces of water were left in the container?
Total water in the container = 18
Water leaked out = 2/3
Ounces of water left = 18 - 2/3(18)
= 18 - 36/3
= 18 - 12
= 6
Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?
Total Number of coins = 18
Dimes = 2/3 of 18
Number of dimes = 2/3 × 18
= 36 / 3
= 12
Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?
Total quarters = 18
Quarters used for game = 2/3 × 18
= 2/3 × 18
= 36 / 3
= 12

A number line goes from 0 to 60. A line is drawn from 2 to 60.
Genevieve is cutting a 60-inch piece of ribbon into a ratio of 2:3. Since 2 inches are frayed at one end of the ribbon, she will need to start 2 inches in. This is indicated as 2 on the number line.
25.2 in.
29.4 in.
35.1 in.
40.7 in.
Answer:
25.2
Step-by-step explanation:
I just got it right on edge.
The location of Genevieve's cut will be at; 25.2 in
We are told that she is cutting a 60 inch piece of ribbon into a ratio of 2:3.Now, 2 inches are frayed at one end of the ribbon and she starts 2 inches in with 2 indicated on the number line. Thus;length available for her to cut = 60 - 2 = 58
Now, the ratio is 2:3. Thus, the length of the parts will be; 2/5 and 3/5.She starts the counting from the frayed end. Thus, the point of cutting will be;
2/5 × 58 = 23.2
Now, since the number line starts from 0 to 60, we will begin our counting from 0 and since she skipped 2 numbers which is the 2 inches that was frayed, we will add 2 to 23.2 to get the exact place her cut will be located. Thus;Location of cut = 2 + 23.2
Location of cut = 25.2 inches

-4n + 9 = -2 (2n -1) +7
Answer:
infinite number of solutions
Step-by-step explanation:
Given
- 4n + 9 = - 2(2n - 1) + 7 ← distribute and simplify right side
- 4n + 9 = - 4n + 2 + 7
- 4n + 9 = - 4n + 9
Since both sides are equal then any value of n makes the equation true.
That is there are an infinite number of solutions

If you can purchase 4 books $18 Then how many can you buy with $27?
Answer:
6
Step-by-step explanation:
if you divide 18 by 4 you get 4.5, and if you divide 27 by 4.5 then you get six. hope this is right :/
Answer: 6 books
Work: Okay, The first thing I did was find out how much one book costs. To find that out, I divided $18/4, and the answer is $4.50 per book. Now, we add $4.50 until it's $27. I did that, and it was just 2 more books. (4.50 + 4.50 is $9, so add nine dollars to $18, and that would be $27. Then, divide 27/4.5, and you get 6, meaning the 6 books)
Sorry if this was confusing, but I hope I helped you. :)

The perimeter of a rectangle is 56 cm. The length of the rectangle is 2 cm more than the width. Find the dimensions of the rectangle.
Length: ____
Width: ____
Answer:
Rectangles! Nice.
Step-by-step explanation:
This is a very simple problem. Let's first represent the width of the rectangle as the variable x.
Then, we know that the length of the triangle is x+2. See where I'm going with this?
The formula for the perimeter of an rectangle is [tex]P=2*Length+2*Width[/tex].
All we have to do next is just input our values for the length and width, and you'll be golden!
[tex]56=2(x+2)+2(x)\\56=4x+4[/tex]
Next to subtract 4 from both sides and then to divide by 4!
[tex]52=4x\\x=13[/tex]
There's your answer! Don't know why Brainly is bugged right now.
NOTE: If you can't read the answer above, the width is 13cm. This also means that the length is 15cm.
