#1 has a typo

you provide no pairs for 2,3,4,5

For #6, you know that x = y+3
So, y = x-3
I assume one of the graphs works for that.

For the rest, work to isolate the variable

#7
-4 = g+1
you want g all alone, so get rid of the 1 with subtraction
-4-1 = g+1-1
-5 = g

the others work the same way. Surely your text has many examples. I know google can provide many more.

Yall, just use mathway for the test and brainley for the word questions
Answered by Bot
While online tools like Mathway and Brainly may be helpful as additional resources, we always recommend double-checking their answers with your teacher or a trusted source to ensure accuracy. Additionally, it's important to remember that cheating is not a good long-term strategy for academic success, and it's important to build a strong understanding of the concepts covered in your math class.
Answer
Bot, can you help me with some questions?
Answered by Bot
Of course! What do you need help with?
Answer
-4=g+1
Answered by Bot
To solve for g, we need to isolate it on one side of the equation. We can do this by subtracting 1 from both sides:

-4 - 1 = g + 1 - 1

Simplifying the right side gives us:

-5 = g

Therefore, the solution for g is -5.

Sure thing! What's the next question?
Answer
x-3=-5
Answered by Bot
To solve for x, we need to isolate it on one side of the equation. We can do this by adding 3 to both sides:

x - 3 + 3 = -5 + 3

Simplifying the right side gives us:

x = -2

Therefore, the solution for x is -2.

I have a few more that Im struggling with if thats okay
Answered by Bot
Of course! I'm here to help. What else do you need assistance with?
Answer
2.8=2y
Answered by Bot
To solve for y, we need to isolate it on one side of the equation. We can do this by dividing both sides by 2:

2.8/2 = 2y/2

Simplifying the left side gives us:

1.4 = y

Therefore, the solution for y is 1.4.
Answer
-9=r/4
Answered by Bot
To solve for r, we need to isolate it on one side of the equation. We can do this by multiplying both sides by 4:

-9 * 4 = r/4 * 4

Simplifying the right side gives us:

-36 = r

Therefore, the solution for r is -36.
Answer
Which equation is an identity?
8-(5x+2)=-5x-6
7z+10-z=8z-2(z-5)
8m-4=5m+8-m
6y+5=6y-5
Answered by Bot
An identity is an equation that holds true for all values of the variable.

Let's simplify each equation and see if any of them are identities:

For the first equation:

8 - (5x + 2) = -5x - 6

8 - 5x - 2 = -5x - 6

6 - 5x = -5x - 6

This equation is not an identity, since 6 does not equal -6 for all values of x.

For the second equation:

7z + 10 - z = 8z - 2(z - 5)

6z + 10 = 8z - 2z + 10

6z + 10 = 6z + 10

This equation is an identity, since both sides of the equation are equal for all values of z.

For the third equation:

8m - 4 = 5m + 8 - m

8m - 4 = 4m + 8

4m = 12

m = 3

This equation is not an identity, since 8m - 4 does not equal 4m + 8 for all values of m.

For the fourth equation:

6y + 5 = 6y - 5

5 = -5

This equation is not an identity, since 5 does not equal -5 for all values of y.

Therefore, the second equation, 7z + 10 - z = 8z - 2(z - 5), is the only identity.
Answer
Which equation has no solution?
5w+4-w=9w-2(w-2)
3x-5=3x+8-x
7z+6=-7z-5
4y+5=4y-6
Answered by Bot
An equation with no solution is one where the variable disappears and the resulting statement is always false.

Let's simplify each equation and see which one has no solution:

For the first equation:

5w + 4 - w = 9w - 2(w - 2)

4w + 4 = 9w - 2w + 4

4w + 4 = 7w + 4

w = 0

This equation is not an equation with no solution.

For the second equation:

3x - 5 = 3x + 8 - x

2x - 5 = 8

2x = 13

x = 6.5

This equation is not an equation with no solution.

For the third equation:

7z + 6 = -7z - 5

14z = -11

z = -11/14

This equation is not an equation with no solution.

For the fourth equation:

4y + 5 = 4y - 6

5 = -6

This equation has no solution, since 5 does not equal -6.

Therefore, the equation, 4y + 5 = 4y - 6, has no solution.
Answer
Ella nad Margaret were at a carnival. They each got a ticket for the Ferris wheel. Ella got a snow cone, and Margaret got a cotton candy. Ella had a certificate for $6 off the cost. Margaret paid the rest, which came to $12.75. Each Ferris wheel ticket was $4, and a snow cone was $3.50. What was the cost for cotton candy?
Answered by Bot
Let `C` be the cost for cotton candy.

First, we know that the cost of both tickets and the snow cone Ella got is equal to the total cost minus the $6 discount:

2(4) + 3.5 - 6 = 5 + 3.5 = 8.5

This means that Margaret paid $12.75 - $8.5 = $4.25 for cotton candy.

Therefore, the cost for cotton candy was $4.25.

Margaret paid the rest, which came to $12.75. Each Ferris wheel ticket was $5, and a snow cone was $3.50. What was the cost for cotton candy?
Answered by Bot
Let's start by calculating the total cost of both tickets and the snow cone that Ella got before the discount:

2(5) + 3.5 = 13.5

Now we can subtract the $6 discount from the total cost:

13.5 - 6 = 7.5

We know that Margaret paid $12.75 in total, so we can subtract Ella's portion to find the cost of the cotton candy:

12.75 - 7.5 = 5.25

Therefore, the cost for cotton candy was $5.25.
Answer
-6p+7=3(2p-3)-4(-10+4p)
Answered by Bot
Let's simplify the equation by distributing the coefficients:

-6p + 7 = 6p - 9 + 40 - 16p

Simplifying the right side of the equation by combining like terms, we get:

-6p + 7 = -10p + 31

Adding 10p to both sides of the equation, we get:

4p + 7 = 31

Subtracting 7 from both sides of the equation, we get:

4p = 24

Dividing both sides of the equation by 4, we get:

p = 6

Therefore, the solution for p is 6.
