Answer:
k=2
Step-by-step explanation:
First your going to switch sides
8k - 3 + 1 = 14
Then your going to do - 3 + 1 = -2
Then you get this equation
8k - 2 = 14
Then your going to add 2 to both sides
8k - 2 + 2 = 14 + 2
Then simplify
8k = 16
Then divide both sides by 8
8k/8 = 16/8
Then simplify again and heres
your answer
k=2
Answer:
14 = 8k - 3 + 1 ; k=2
Step-by-step explanation:
14= 8k - 3 + 1
switch sides:
8k -3 + 1 =14
add/subtract the numbers:
8k-2+2=14+2
simplify:
8k=16
divide both sides by 8:
8k/8 = 16/8
simplify:
k=2

Following the previous question, how much does the video game cost after taking 30% off? (Subtract total cost and money saved)
Answer:
Well for example most video games cost $60, so if you divide the original price by 100 and multiply it by 30, you'll get 18, so you take away that from 60, then you'll get 42.
Step-by-step explanation:
60 divided by 100 = 0.6, times that by 30 = 18, take away that from the original price which was 60, you'll get 42.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
If the cost of the video game is $60
The cost of the video game after 30% off is $42
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
We will assume that the cost of the video game = $60
Percentage off = 30%
30% = 30/100
30% of 60 = 30/100 x 60 = 18
The cost after 30% off.
= $60 - 30% of $60
= 60 - 30/100 x 60
= 60 - 18
= $42
Thus,
If the cost of the video game is $60
The cost of the video game after 30% off is $42

What you first want to do is like and unlike terms so basically liketerms are terms withthe same sign and unlike terms are terms with diferent signs for instinse 3g and 2g are like terms so -33 and -9 and -9 and 9 are unlike terms so you just have to find the like and unlike terms to answer the question!
Answer: -9
Step-by-step explanation: Let's solve your equation step-by-step.
3g+15−12+3−2g+4=1
Step 1: Simplify both sides of the equation.
3g+15−12+3−2g+4=1
3g+15+−12+3+−2g+4=1
(3g+−2g)+(15+−12+3+4)=1 (Combine Like Terms)
g+10=1
g+10=1
Step 2: Subtract 10 from both sides.
g+10−10=1−10
g=−9
So the answer is g=-9

Please list the number of 30, 5, 6, 8 cent stamps he has.
First gets Brainliest!!!
Answer:
12 of the 5 cents stamps,
20 of the 6 cents stamps
15 of the 8 cents stamps
10 of the 30 cents stamps.
Step-by-step explanation:
Let's name:
x = number of 5 cent stamps,
w = number of 6 cent stamps,
y = number of 8 cent stamps,
z = number of 30 cent stamps,
Create the following system of equations based on the info provided:
z + 5 = y
w = 2 * z
x = 12
600 = 5 (12) + 6 w + 8 y + 30 z
replace everything in terms of "z":
600 = 60 + 6 (2 * z) + 8 (z + 5) + 30 z
540 = 12 z + 8 z + 40 + 30 z
500 = 50 z
z = 10
and now we can find the rest:
y = 5 + 10 = 15
w = 2 * 10 = 20
Therefore there are:
12 of the 5 cents stamps,
20 of the 6 cents stamps
15 of the 8 cents stamps
10 of the 30 cents stamps.

Answer:
(x, y) --> (x + 2, y - 3)
Step-by-step explanation:
2 is positive and 3 in negative
The rule describes the translation that was applied to triangle ABC to create triangle A'B'C is (x, y) → (x+2, y-3). Therefore, option B is the correct answer.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Given that, triangle ABC was translated 2 units to the right and 3 units down.
Translation rules:
When the shape is moved towards the right by k units, then replace x with x + k.
When the shape is moved down by k units, then replace y with y - k.
Here, the rule is (x, y) → (x+2, y-3)
Therefore, option B is the correct answer.

The required values of ratios are 9/16,3/2, 7/6 and 1/12 respectively. The only false option is (c).
What is the application ratio and proportion?A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.
Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.
All the options are examined one by one as follows,
(a) The ratio of 5/8 to 10/9 is given as,
5/8 : 10/9
= (5/8) ÷ (10/9)
= 5/8 × 9/10
= 9/16
Thus, it is true.
(b) The ratio of 4/7 ∶ 8/21 is given as,
4/7 ∶ 8/21
= (4/7) ÷ (8/21)
= 4/7 × 21/8
= 3/2
Thus, it is true.
(c) The unit rate of 7/9 and 2/3 equivalent to the ratio given below,
7/9 : 2/3
= 7/9 ÷ 2/3
= 7/9 × 3/2
= 7/6
Thus, it is false.
(d) The unit rate of 9/16 and 27/4 equivalent to the ratio given below,
9/16 : 27/4
= 9/16 ÷ 27/4
= 9/16 × 4/27
= 1/12
Thus, it is true.
Hence, the ratios for the given options are obtained as 9/16,3/2, 7/6 and 1/12 respectively.

t = 8
Step-by-step explanation:

1. For a party, Susan estimated there would be 14 people in attendance, but only 12 showed up. What was the percent error in her estimation?
2. Find the percent error in this situation:
Estimated value: 231
Actual value: 215
3. Find the percent error in this situation:
Experimental value: 16.5 sec
Theoretical value: 17.1 sec
4. Find the percent error in this situation:
Estimated value: 1081
Actual value: 1150
The formula for percent error is:
((Approximate value - exact value) / exact value) x 100
1) 14-12 = 2
2/12 = 0.1666
0.166 x 100 = 16.7% (Rounded to nearest tenth)
2) 231 - 215 = 16
16/215 = 0.74419
0.74419 x 100 = 7.4419% ( Round as needed)
3) 17.1 - 16.5 = 0.6
0.6/16.5 = 0.36364
0.36364 x 100 = 3.6364% (Round off as needed)
