wrong
Apologies for the incorrect response. Let's solve it correctly.
k - 2 = -10
We can isolate k by adding 2 to both sides:
k - 2 + 2 = -10 + 2
This simplifies to:
k = -8
Therefore, the correct solution is k = -8.
k - 2 = -10
We can isolate k by adding 2 to both sides:
k - 2 + 2 = -10 + 2
This simplifies to:
k = -8
Therefore, the correct solution is k = -8.
Solve for k.
k/−2=−10
k/−2=−10
To solve for k, we need to isolate it on one side of the equation.
Divide both sides of the equation by -2:
(k/(-2)) = (-10)/(-2)
This simplifies to:
k = 5
Therefore, the solution for k is k = 5.
Divide both sides of the equation by -2:
(k/(-2)) = (-10)/(-2)
This simplifies to:
k = 5
Therefore, the solution for k is k = 5.
Solve for y.
5y−10=−25
5y−10=−25
To solve for y, we will isolate it on one side of the equation.
Starting with the given equation:
5y - 10 = -25
First, we will add 10 to both sides of the equation to get rid of the -10 term on the left side:
5y - 10 + 10 = -25 + 10
This simplifies to:
5y = -15
Next, we will divide both sides of the equation by 5 to solve for y:
(5y)/5 = (-15)/5
This simplifies to:
y = -3
Therefore, the solution for y is y = -3.
Starting with the given equation:
5y - 10 = -25
First, we will add 10 to both sides of the equation to get rid of the -10 term on the left side:
5y - 10 + 10 = -25 + 10
This simplifies to:
5y = -15

(5y)/5 = (-15)/5
This simplifies to:
y = -3
Therefore, the solution for y is y = -3.
Solve for x.
−3x+4=−8
−3x+4=−8
To solve for x, we will isolate it on one side of the equation.
Starting with the given equation:
-3x + 4 = -8
First, we will subtract 4 from both sides of the equation to get rid of the +4 term on the left side:
-3x + 4 - 4 = -8 - 4
This simplifies to:
-3x = -12
Next, we will divide both sides of the equation by -3 to solve for x:
(-3x) / -3 = (-12) / -3
This simplifies to:
x = 4
Therefore, the solution for x is x = 4.
Starting with the given equation:
-3x + 4 = -8
First, we will subtract 4 from both sides of the equation to get rid of the +4 term on the left side:
-3x + 4 - 4 = -8 - 4
This simplifies to:
-3x = -12

(-3x) / -3 = (-12) / -3
This simplifies to:
x = 4
Therefore, the solution for x is x = 4.
Solve for w.
−0.1w+23.2=−0.8
−0.1w+23.2=−0.8
To solve for w, we will isolate it on one side of the equation.
Starting with the given equation:
-0.1w + 23.2 = -0.8
First, we will subtract 23.2 from both sides of the equation to get rid of the +23.2 term on the left side:
-0.1w + 23.2 - 23.2 = -0.8 - 23.2
This simplifies to:
-0.1w = -24
Next, we will divide both sides of the equation by -0.1 to solve for w:
(-0.1w) / (-0.1) = (-24) / (-0.1)
This simplifies to:
w = 240
Therefore, the solution for w is w = 240.
Starting with the given equation:
-0.1w + 23.2 = -0.8
First, we will subtract 23.2 from both sides of the equation to get rid of the +23.2 term on the left side:
-0.1w + 23.2 - 23.2 = -0.8 - 23.2
This simplifies to:
-0.1w = -24
Next, we will divide both sides of the equation by -0.1 to solve for w:
(-0.1w) / (-0.1) = (-24) / (-0.1)
This simplifies to:
w = 240
Therefore, the solution for w is w = 240.

Cody has 22 rare coins. Each year Clark plans to add 15 coins to his collection. How many years will it take Cody to collect 577 coins?
To determine the number of years it will take for Cody to collect 577 coins, we need to find the difference between the target number of coins (577) and the initial number of coins Cody already has (22). Then, we can divide this difference by the number of coins Clark plans to add to his collection each year (15).
Difference = 577 - 22 = 555
Years = Difference / 15 = 555 / 15 ≈ 37
Therefore, it will take approximately 37 years for Cody to collect 577 coins.
Difference = 577 - 22 = 555
Years = Difference / 15 = 555 / 15 ≈ 37
Therefore, it will take approximately 37 years for Cody to collect 577 coins.
Tom is given the equation 10x+15=20
to solve. He says the solution is 1/2
. Which reason justifies his solution?
to solve. He says the solution is 1/2
. Which reason justifies his solution?
The reason that justifies Tom's solution of 1/2 for the equation 10x + 15 = 20 is that when you substitute x = 1/2 into the equation, it makes the equation true.
Let's substitute x = 1/2 into the equation and check if it is satisfied:
10(1/2) + 15 = 20
5 + 15 = 20
20 = 20
Since the equation is true when x = 1/2, it confirms that 1/2 is indeed the solution to the equation.

Dr. Burrows is measuring the weight of a substance for a science experiment. He added a mystery substance (m) to his experiment. Dr. Burrows used the equation 13.93 + m = 18.0 to find out how much he added. How much of the mystery substance (m) did he add to his experiment?
To find out how much of the mystery substance Dr. Burrows added to his experiment, we need to solve the equation 13.93 + m = 18.0 for m.
We can isolate m by subtracting 13.93 from both sides of the equation:
m = 18.0 - 13.93
This simplifies to:
m = 4.07
Therefore, Dr. Burrows added 4.07 units of the mystery substance to his experiment.
We can isolate m by subtracting 13.93 from both sides of the equation:
m = 18.0 - 13.93
This simplifies to:
m = 4.07
Therefore, Dr. Burrows added 4.07 units of the mystery substance to his experiment.

If Jaylan takes the number of stamps he has and multiplies it by 5 and then subtracts 10, he gets 275. How many stamps does he have?
To determine how many stamps Jaylan has, we can use the given information to set up an equation.
Let's represent the number of stamps Jaylan has with the variable s. According to the problem, the equation can be written as:
5s - 10 = 275
To solve for s, we will isolate the variable by adding 10 to both sides of the equation:
5s - 10 + 10 = 275 + 10
This simplifies to:
5s = 285
Next, we will divide both sides of the equation by 5 to solve for s:
(5s) / 5 = 285 / 5
This simplifies to:
s = 57
Therefore, Jaylan has 57 stamps.
Let's represent the number of stamps Jaylan has with the variable s. According to the problem, the equation can be written as:
5s - 10 = 275

Next, to isolate the term with w, we can subtract 12.50 from both sides of the equation:
40w + 12.50 - 12.50 = 492.50 - 12.50
This simplifies to:
40w = 480
To solve for w, we need to divide both sides of the equation by 40:
(40w) / 40 = 480 / 40
This simplifies to:
w = 12
Therefore, the solution for w is w = 12.
Starting with the given equation:
