or
infinitely many solutions
The given equation 3y = -12x + 6 has infinitely many solutions.
The given equation 3y = -12x + 6 can be solved using the substitution method to determine whether this equation has no solution, 1 solution or infinitely many solutions.
Given equation,
3y = -12x + 6
Rearranging the terms of the equation, we get the value of y in terms of the variable x.
=> 3y = -12x + 6
=> y = -12x/3 + 6/3
=> y = -4x + 2
Next, we substitute this value of y in terms of the variable x in the original equation,
=> 3 ( -4x + 2 ) = -12x + 6
=> -12x + 6 = -12x + 6
=> -12x + 12x = 6 - 6
=> 0 = 0
From the obtained result, we can conclude that this system has infinitely many solutions. This implies, the lines are coincident and the system is consistent and dependent.
Therefore, it can be concluded that the given equation 3y = -12x + 6 has infinitely many solutions.

a vineyard has 145 acres of chardonnay grapes. a particular soil supplement requires 5.50 gg for every square meter of vineyard. how many kilograms of the soil supplement are required for the entire vineyard? (recall that 1 km2
3230 kilograms of the soil supplement are required for the entire vineyard;
1 km = 1000 m = 10³ m
1 km² = 1000000 m² = 10⁶ m²
1 km² = 247 acres
1 kg = 1000 g;
A vineyard has 145 acres of Chardonnay grapes.
145 acres = 145/247 km²
= 0.587 km²
A particular soil supplement requires 5.50 grams for every square meter of vineyard.

Write a system of equations that could be used to determine the number of hours Shandra worked washing cars last week and the number of hours she worked walking dogs last week. Define the variables that you use to write the system. Let Let ||| System of Equations:
Step-by-step explanation:
x=total hours for wahing cars
y=total hours for walking dogs
1. 9x+8y=90 (total money)
2. x+y=11 (total hours)
=>8x+8y=88
=> 1-2
=> x=2
therefore y=9
The number of hours for Shandra working to wash car is 2 hours.
The number of hours for Shandra working to walking dogs is 9 hours.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Shandra is working two summer jobs, making $9 per hour washing cars and $8 per hour walking dogs.
Last week Shandra worked a total of 11 hours.
Total earned = $90
Now,
Total number of hours to wash car = x
Total number of hours to walk dogs = y
So, We can formulate;
⇒ 9x + 8y = $90 ... (I)
And, x + y = 11 .. (ii)
Solve equation (i) and (ii) we get;
x = 2 hours and y = 9 hours
So, The number of hours for Shandra working to wash car is 2 hours.
The number of hours for Shandra working to walking dogs is 9 hours.

i have two 20-sided dice that each have 4 maroon sides, 7 teal sides, 8 cyan sides, and one sparkly side. if i roll both dice, what is the probability they come up the same?
The probability of color coming up the same for rolling two 20-sided dice is 129/400.
Probability is defined as how likely something is to happen. For a single dice, getting a maroon, teal, and cyan have a probability of 4/20, 7/20, and 8/20, respectively.
Before solving the probability, we must identify whether the events are considered independent or dependent. Independent events are when the probability of an event happening does not affect the other's event probability of happening. A dependent event is when the probability of an event happening affects the other event. The rolling of dice is considered an independent event.
For events that should occur together, the multiplication rule is used. To solve for the probability of two sides coming up the same, the formula below is used.
P (A and B) = P (A) * P (B)
P (red and red) = (4/20)*(4/20) = 1/25
P (teal and teal) = (7/20)*(7/20) = 49/400
P (cyan and cyan) = (8/20)*(8/20) = 4/25
Since no specific color was stated in the problem, the sum of the probability of each color coming up the same is determined.
P (color come up the same) = P (red and red) + P (teal and teal) + P (cyan and cyan)
P (color come up the same) = 1/25 + 49/400 + 4/25
P (color come up the same) = 129/400
