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
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

Answer:
4xy exponent 7/2xy exponent 6
Answer:
Step-by-step explanation:
First expand the numerator by distributing in the 2 outside the parenthesis to get
[tex]\frac{16x^6y^4}{2x^6y}[/tex] and now, working on one thing at a time, we will divide:
16 x⁶ y⁴
2 x⁶ y
I separated each set of like expressions to make it easier to see. First divide the numbers, 16 by 2:
8 x⁶ y⁴
x⁶ y
the x's cancel out (divide to a 1):
8 y⁴
y
and by the rules for dividing like bases, we will subtract the exponents, lower from upper to get, finally:
8y³

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] \leadsto \frak{Area = \frac{1}{ \cancel2} × \cancel 8 \times 6 }[/tex]

Hey guys so I have a question. How do you determine the appropriate center of measure? I know that you have to find the mean median and mode but once you find the mean median and mode, how do you determine the center of measure? I'm confused.
Answer:
The two most widely used measures of the “center” of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50 . To find the median weight of the 50 people, order the data and find the number that splits the data into two equal parts.

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

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
Part B:
$ 7 per foot
