Answer: x=-2 and y=-2
Step-by-step-explaination:
To solve the system of equations you have to cancel out a variable. I chose to cancel out Y. First, the coefficients of y need to be the same in both equations. To do this multiply to the top equation by 2 so you get
2(2x) +2(y) = 2(-6)
4x + 2y = -12
Next, subtract the second equation from the first to cancel out the y’s
4x + 2y =-12
-(-8x + 2y = -12)
————————
12x = -24
Solve
X = -24/12
X=-2
Plug x into the original equation to find y
2(-2) + y = -6
-4 + y = -6
Y = -6 +4
Y=-2
You can substitute x and y into the original equations to double check
Answer: <em>I think the answer is 5</em>
Step-by-step explanation:
The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables or numbers.
The magnitude of the second atom relative to the first = magnitude of second atom / magnitude of first atom
The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100

Answer:
Total cost= $235
Step-by-step explanation:
Giving the following information:
Dontae wants to buy 100 tiles for his kitchen floor. The tiles cost $2.35.
<u>To calculate the total cost, we need to use the following formula:</u>
Total cost= 2.35*x
x= number of tiles
<u>For 100 tiles:</u>
Total cost= 2.35*100
Total cost= $235
The area the goat can graze is 1/2π(50)²= 1250π sq. feet
The rope length is 50 feet again, thus the results are the same.
1/2π(50)²= 1250π sq. feet
