Solve the equation -3(x - 14) + 9x = 6x + 42. Does the equation have one solution, no solution, or infinitely many solutions?
Answers
Hello!
[tex]\large\boxed{\text{Infinitely many solutions.}}[/tex]
-3(x - 14) + 9x = 6x + 42
Distribute the coefficient of the parenthesis:
-3(x) - 3(-14) + 9x = 6x + 42
-3x + 42 + 9x = 6x + 42
Combine like terms:
6x + 42 = 6x + 42
Both sides of the equation are the same, therefore:
There are infinitely many solutions.
⠀⠀⠀⠀
Equation have Infinitely many Solutions⠀⠀⠀⠀
______________________
⠀⠀⠀⠀
➤ How to solve ?⠀⠀⠀⠀
For solving such problems we need to recall equations .
⠀⠀⠀⠀
When the value of two variable comes equal and zero in an equation then that equation is said to have infinitely many solutions . If the value of a variable have any particular constant then the equation is said to have one solution . If the value of of any variable comes undefine then the equation is said to have no solution .
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
⠀⠀⠀⠀
SolutiOn :➠ - 3 ( x - 14 ) + 9x = 6x + 42
➠ -3x + 42 + 9x = 6x + 42
Now, we will bring the variable on left hand side and constants on right hand side
➠ -3x + 9x - 6x = 42 - 42
➠ -9x + 9x = 42 - 42
➠ 0 = 42 - 42
➠ 0 = 0
As we can see the equation have end with a zero the equation have indefinitely many solutions
➠ Indefinity many solutions

A department store sells a pair of shoes with an 87% markup. If the store sells the shoes for $193.21 then what is their non-markup price?
Answers
Step-by-step explanation:
87% + 100% = 187%
187% of original price = $193.21
100% of original price = $193.21 * (100/187) = $103.32.
The non-markup price is $103.32.
Answer:
87% + 100% = 187%
187% of original price = $193.21
100% of original price = $193.21 * (100/187) = $103.32.
The non-markup price is $103.32.

The obriens are buying new windows for their house. The company installs the new windows for 2100 the total cost for buying the windows and having them installed is 5323.50 of the o'briens pay 230.25 per window how many windows did they buy
Answers
Answer:
14
Step-by-step explanation:
Given that:
Cost of purchase and installation = 5323.50
Cost per window = 230.25
Cost of installation = 2100
Hence,
Total purchase cost of windows alone :
5323.50 - 2100 = 3,223.50
Therefore, the number of windows purchased is :
(Total purchase cost of windows alone / price per window)
(3,223.50 / 230.25)
= 14
Hence, 14 windows was purchased

Moises ate 10% of the candies in the bag. If Moises ate 16 candies, how many candies were there total in the bag?
Answers
Answer:
160
Step-by-step explanation:
10% of the candies is 16, and to get 100% from 10% is to multiply by 10.
So 10% *10 = 100%, then by association if 16 = 10%, then 16*10 will be the total 100%.

My remainder is 8. My dividend is 80. I am a 1- digit number. What divisor am I?
Answers
Answer:
9 is the answer..
Step-by-step explanation:
pls mark me the brainliest
Answer:
The divisor is 9.
Step-by-step explanation:
a) Data and Calculations:
Remainder = 8
Dividend = 80
Number divided evenly without remainder 8 = 80 - 8 = 72
72/9 = 8
b)There are four main numbers under the divisional mathematical rule. The first number is the dividend which is the number 80 that is being divided by the divisor. The divisor (9) is the number that divides 80. The quotient (8) is the result obtained by the division, while the remainder 8 is the number left over after the division.
