Answer:
x=5/3, and x=-1
Step-by-step explanation:
The absolute value sign makes anything inside of it positive. So there are two possible x values for this problem. When we open the absolute value brackets we need to create two different equations. 3x-1=4, and 3x-1= -4. Solving these two equations we can find two possible values of x. x equals 5/3, and -1.
Step by step plz on how to do this
Answer:
x=3
Step-by-step explanation:
Step 1: you have to replace y with x-6 to make it all one equation (as seen in the picture below)
Step 2: write it all together so: x-6= -2x+3
Step 3: add 2x on both sides to cancel out the negative so: x+ 2x and -2x+2x
Step 4: add 6 on both sides to cancel out the negative so: -6+ 6 and 3+6
Step 5: divide 3 by 3x and 9 to get x

I need help with my math!!
Answer:
5
Step-by-step explanation:
12 - 7 = 5
Using Pythagoras Theorem
Hyp² = Adjacent² + Opp²
13² = d² = 12²
d² = 13² - 12²
d² = 169 - 144
d² = 25
d = √25
d = 5
The correct answer is 5, OPTION C IS CORRECT

Write two equivalent ratios using four different types of music in the data table showing. How do you know the ratios are equivalent?
rock-12
classic rock-4
county-18
jazz-2
heavy metal-6
PLEASE HELP! It was due 3 days ago lol
Answer:
Part A:
The ratios in the table are equivalent.
The two quantities in this table represent a proportional relationship.
The graph of the relationship would be straight line through origin
Step-by-step explanation:
Part A
The ratios in the table are equivalent.
Length: Cost
6 : 42 = 1 : 7
15: 105 = 1: 7
24 : 168 = 1:7
30 : 210 = 1 : 7
The two quantities in this table represent a proportional relationship.
If we take length = x, then cost =7x
When length = 6 , Cost = 7 *6 = 42
When length = 15 , Cost = 7 * 15 = 105
When length = 24 , Cost = 7 *24 = 168
The graph of the relationship would be straight line through origin
y = 7x
y -> cost and x -> length
When x = 0 , y= 0. so, this graph go through the origin

Steve buys a wallet that costs $35.00. He pays 10% sales tax. How much does he pay for the wallet with tax?
A. $48.50
B. $38.50
C. $18.50
D. $45.50
Answer:
B. $38.50
Step-by-step explanation:
The original price of item (before tax) is 100% of the price of the item since 100% means the whole amount.
The tax is 10% of the original price, so add 10% to 100% making it 110%.
The total price including tax is 110% of the original price.
We need to find 110% of $35.00.
To find a percent of a number, multiply the percent by the number.
110% of $35.00 = 110% * $35.00
Change the percent to a decimal by moving the decimal point two places to the left.
110% becomes 1.10 as a decimal
110% of $35.00 = 110% * $35.00 = 1.10 * $35.00 = $38.50
Answer: B. $38.50

the x's cancel out (divide to a 1):

The area of a triangle is found using the formula bh/2, where b is the base and h is the height. What is the area in square inches of a triangle with a height of 6 inches and a base of 8 inches?
Answer:
A = 24 in^2
Step-by-step explanation:
A = 1/2 bh
Let b = 8 and h = 6
A = 1/2 (8)(6)
A = 24 in^2
The area of a triangle is found using the formula bh/2, where b is the base and h is the height. What is the area in square inches of a triangle with a height of 6 inches and a base of 8 inches?
Solution :Given Data :
Height = 6 inches
Base = 8 inches
Formula for Area of traingle is :
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \star \: \: \: \red{ \underline{ \red{ \overline{ \orange{ \boxed{ \pink{\frak{Area \: of \: Triangle = \frac{1}{2} × Base × Height }}}}}}}}[/tex]
So, putting the values of Base and Height we get
[tex] \leadsto \frak{Area = \frac{1}{2} × 8 \times 6 }[/tex]
[tex] \leadsto \frak{Area = \frac{1}{ \cancel2} × \cancel 8 \times 6 }[/tex]
[tex] \leadsto \frak{Area = 4 \times 6 }[/tex]

Angie and Kenny play online video games. Angie buys 1 software package and 2 months of game play. Kenny buys 1 software packages and 6 months of gameplay. Each software package costs $50. If their total is $250, what is the cost of one month of gameplay?
Answer:
$18.75 is the cost for 1 month of gameplay.
Step-by-step explanation:
2 software packages in total
Unit price for software package is $50, and since there are two packages, $50x2=$100
Now, we know that the total amount of money that the software cost was $100, we can do 250-100=150
150 is how much they spent for 8 months of gameplay. (2+6=8)
To find how much 1 month of gameplay costs, we need to do 150/8 which is equivalent to $18.75
