The correct solution to the equation y = 3x – 1 is (2, 5).
Which equation matches the statement: “The sum of –4x and 2 is 9”? (1 point) Responses –4x 2 = 9 –4 x 2 = 9 –4x 9 = 2 –4 x 9 = 2 –4x(2) = 9 –4 x (2) = 9 –4x – 2 = 9
The equation that matches the statement "The sum of –4x and 2 is 9" is -4x + 2 = 9.
Solve. x – 6 = –18 (1 point) Responses x = –24 x = –24 x = –12 x = –12 x = 12 x = 12 x = 6
To solve the equation x - 6 = -18, we need to isolate the variable x.
Adding 6 to both sides of the equation, we get:
x - 6 + 6 = -18 + 6
This simplifies to:
x = -12
Therefore, the solution to the equation x - 6 = -18 is x = -12.
Adding 6 to both sides of the equation, we get:
x - 6 + 6 = -18 + 6
This simplifies to:
x = -12
Therefore, the solution to the equation x - 6 = -18 is x = -12.
Solve. 4x 3 = 47 (1 point) Responses x = 11 x = 11 x = 40 x = 40 x = 44 x = 44 x = 50
To solve the equation 4x + 3 = 47, we need to isolate the variable x.
Subtracting 3 from both sides of the equation, we get:
4x + 3 - 3 = 47 - 3
This simplifies to:
4x = 44
Dividing both sides of the equation by 4, we get:
x = 11
Therefore, the solution to the equation 4x + 3 = 47 is x = 11.
Subtracting 3 from both sides of the equation, we get:
4x + 3 - 3 = 47 - 3
This simplifies to:
4x = 44
Dividing both sides of the equation by 4, we get:
x = 11
Therefore, the solution to the equation 4x + 3 = 47 is x = 11.
Solve. x = 12 (1 point) Responses x = 4 x = 4 x = 15 x = 15 x = 36 x = 36 x = 39 x = 39
The solution to the equation x = 12 is x = 12. Therefore, none of the provided responses is correct.
Solve. 3x 3 = 21 (1 point) Responses x = 5 x = 5 x = 6 x = 6 x = 18 x = 18 x = 36
To solve the equation 3x + 3 = 21, we need to isolate the variable x.
Subtracting 3 from both sides of the equation, we get:
3x + 3 - 3 = 21 - 3
This simplifies to:
3x = 18
Dividing both sides of the equation by 3, we get:
x = 6
Therefore, the solution to the equation 3x + 3 = 21 is x = 6.
Subtracting 3 from both sides of the equation, we get:
3x + 3 - 3 = 21 - 3
This simplifies to:
3x = 18
Dividing both sides of the equation by 3, we get:
x = 6
Therefore, the solution to the equation 3x + 3 = 21 is x = 6.
Solve. x – 4 = 16 (1 point) Responses x = 20 x = 20 x = 13 x = 13 Image with alt text: start fraction 1 over 3 end fraction x = 15 x = 15 Image with alt text: start fraction 1 over 3 end fraction 30 30
To solve the equation x - 4 = 16, we need to isolate the variable x.
Adding 4 to both sides of the equation, we get:
x - 4 + 4 = 16 + 4
This simplifies to:
x = 20
Therefore, the solution to the equation x - 4 = 16 is x = 20.
Adding 4 to both sides of the equation, we get:
x - 4 + 4 = 16 + 4
This simplifies to:
x = 20
Therefore, the solution to the equation x - 4 = 16 is x = 20.
Use the given equation to find the solution to the following problem. The equation 9.95 0.30s = c gives the cost c in dollars that a website charges for downloading songs. The variable s stands for the number of songs downloaded. Find the cost of downloading 35 songs. (1 point) Responses c = $9.95 c = $9.95 c = $20.45 c = $20.45 c = $35.00 c = $35.00 c = $114.45
To find the cost of downloading 35 songs using the equation 9.95 + 0.30s = c, we substitute s = 35 into the equation.
c = 9.95 + 0.30(35)
c = 9.95 + 10.50
c = 20.45
Therefore, the cost of downloading 35 songs is $20.45.
c = 9.95 + 0.30(35)
c = 9.95 + 10.50
c = 20.45
Therefore, the cost of downloading 35 songs is $20.45.
Write an equation and solve to find the solution to the following problem. You have $27 to spend at the mall and a coupon for $6 off at your favorite store. A t-shirt costs $11. How many t-shirts can you buy using your coupon and money? (1 point) Responses 1 shirt 1 shirt 2 shirts 2 shirts 3 shirts 3 shirts 4 shirts
Let x be the number of t-shirts you can buy.
The cost of each t-shirt after using the coupon would be $11 - $6 = $5.
So the total cost of x t-shirts would be 5x.
We know that the total amount you can spend is $27. Therefore, we can write the equation:
5x = 27
To solve for x, we divide both sides of the equation by 5:
x = 27/5
x ≈ 5.4
Since you can't buy a fraction of a t-shirt, the maximum number of t-shirts you can buy is 5.
Therefore, you can buy 5 shirts using your coupon and money.
The cost of each t-shirt after using the coupon would be $11 - $6 = $5.
So the total cost of x t-shirts would be 5x.
We know that the total amount you can spend is $27. Therefore, we can write the equation:
5x = 27
To solve for x, we divide both sides of the equation by 5:
x = 27/5
x ≈ 5.4
Since you can't buy a fraction of a t-shirt, the maximum number of t-shirts you can buy is 5.
Therefore, you can buy 5 shirts using your coupon and money.
