Step-by-step explanation:
follow a few exponent rules and you can figure this out
when expoenents are to the power of something you can mutilply the expoents.. and when there is a minus sign in the exponent.. it's like the reciprocal [tex]x^{-2}[/tex] is 1/[tex]x^{2}[/tex] soooo...
mutilply the -2/3 by each of the exponents in the question the 8 is tricky b/c it has an invisible 1 on it :o
= [tex]8^{-2/3}[/tex][tex]w^{-14/3}[/tex][tex]x^{10/3}[/tex][tex]y^{-6/3}[/tex][tex]z^{18/3}[/tex]
= 1/[tex]\sqrt[3]{8*8}[/tex] * 1/[tex]w^{14/3}[/tex] * [tex]x^{10/3}[/tex] * 1/[tex]y^{2}[/tex] * [tex]z^{6}[/tex]
= 1/[tex]\sqrt[3]{64}[/tex]* 1/[tex]w^{14/3}[/tex] *[tex]x^{10/3}[/tex] * 1/[tex]y^{2}[/tex] * [tex]z^{6}[/tex]
= 1/4* 1/[tex]w^{14/3}[/tex] *[tex]x^{10/3}[/tex] * 1/[tex]y^{2}[/tex] * [tex]z^{6}[/tex]

Dylan scored a total of 48 points in the first four games of basketball season which equation can be used to find g e d average number of points he scored per game
Answer:
[tex]\dfrac{48}{4}=12[/tex]
Step-by-step explanation:
Given that:
Dylan plays basketball.
In the season, he scored 48 points in total in the first four games of the season.
To find:
The equation to represent the average number of points scored per game.
Solution:
Average is the term used to find one number which can be used to represent a list.
It is usually the mid value.
Average can be found by using the following formula:
[tex]\text{Average =} \dfrac{\text{Sum of all the observations}}{\text{Number of observations}}[/tex]
Here, Sum of all the observations is the total score which is given as 48.
Number of observation is nothing but the number of games which is given as 4.
Therefore, the equation to find the average can be written as:
[tex]Average = \dfrac{48}{4}\\ \Rightarrow \bold{Average = 12}[/tex]
Jose bought 3 pens and 6 pencils for $6.60. Amy bought 5 pens and 8 pencils for $10.00. How much does one pencil cost?
Appreciate it :)
Answer:
pen = $1.20, pencil = $0.50
Step-by-step explanation:
let x = pen
let y = pencil
create system of equations:
3x + 6y = 6.60 [can be simplified to be x + 2y = 2.20]
5x + 8y = 10.00
substitution method:
x = 2.2 - 2y
5(2.2 - 2y) + 8y = 10
11 - 10y + 8y = 10
-2y = -1
y = 1/2
solve for 'x':
3x + 6(1/2) = 6.6
3x + 3 = 6.6
3x = 3.6
x = 1.2
(9.74c - 250.50) + (-5.48p + 185.70)
Step-by-step explanation:
explain to me what you are asking
Answer:
9.74c-5.48p-64.8
Step-by-step explanation:
(9.74c-250.50)+(-5.48p+185.70)
9.74c-250.50-5.48p+185.70
Combine like terms
-250.50+185.70= -64.8
-64.8+9.74c-5.48p
Reorder them (variables first <alphabetically> then, a number)
9.74c-5.48p-64.8

solve the inequality: 8(7-x)<64
Answer: x>-1
solving For X
Answer:
x > -1
Step-by-step explanation:
8(7-x)<64 (solve for x)
56 - 8x < 64 (distribute!)
-8x < 8 (subtracted 56 from both sides)
x > -1 (divide by -8, flip sign anytime you divide by a negative!)

A television that costs $500 is marked up 250%. What
is the new price of the television?
Cost - 500
Marked Up - 250
Margin - 71.4286
MxCxMA= $1,750
This may seem confusing, but its $1,750 for the new price, and the equation is:
M= Marked
C= Cost
MA= Margin
The new price of the television is $1750.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
A television that costs $500 is marked up 250%.
So, the new price is
= 500 + 250% of 500
= 500 + 250/100 x 500
= 500 + 1250
= $1750
Hence, the new price of the television is $1750.

Simplify 3(5a + b) + 4(a + 2b).
A.) 9a + 5b
B.) 19a + 3b
C.) 19a+11b
D.) 9a + 9b
Answer:
C. 19a + 11b
Step-by-step explanation:
Distribute into the parentheses.
3(5a + b) + 4(a + 2b)
= 15a + 3b + 4a + 8b
Add like terms.
15a + 3b + 4a + 8b
19a + 3b + 8b
= 19a + 11b
Hope that helps.
Hey there!
“Simplify 3(5a + b) + 4(a + 2b)”
FIRST you have to DISTRIBUTE
3(5a + b) + 4(a + 2b)
3(5a) + 3(b) + 4(a) + 4(2b)
3(5a) = 15a
3(b) = 3b
4(a) = 4a
4(2b) = 8b
“15a + 3b + 4a + 8b”
SECOND: COMBINE your LIKE TERMS
(3b + 8b) + (15a + 4a)
(3b + 8b) = 11b ⬅️ BACK number
(15a + 4a) = 19a ⬅️ FRONT number
ALL OF YOUR TERMS/NUMBERS ARE POSITIVE SO WE DON’T HAVE TO FIX ANYTHING
Answer: C. 19a + 11b ☑️
Good luck on your assignment and enjoy your day!

The function c(x) = 18x -10 represents the cost in dollars. How many tickets can you buy?
Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.
So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 98 dollars.
The solution would still clear your concept though.
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept
Given the function
c(x) = 18x -10
comparing with the slope-intercept form of the line equation
rate of change = slope = m = 18c(x) or y represents the costAccording to the function equation,
'x' represents the number of ticketsAssuming the total cost i.e. c(x) = $98
In order to determine the value of x, set c(x) = 98
i.e.
98 = 18x -10
switch sides
18x - 10 = 98
add 10 to both sides
18x - 10 + 10 = 98 + 10
18x = 108
Divide 18 to both sides
18x/18 = 108/18
x = 6
Therefore, if you can buy x = 6 if you pay 98 dollars.
