<u>Let's solve this problem step-by-step</u>
<u>Let's set</u>:
2x + 6y = 36 -- equation 1
x + 4y = 20 -- equation 2
(equation 2) * 2
2x + 8y = 40 -- equation 3
(equation 3) - (equation 1)
2y = 4
y = 2 -- equation 4
Plug (equation 4)'s value of y into (equation 2)
x + 4(2) = 20
x = 20 - 8
x = 12
<u>Thus x = 12 and y = 2</u>
<u>Let's check, by substituting these values</u>
<u>Answer: x = 12 and y = 2</u>
Hope that helps!
Answer:
X = -1
Step-by-step explanation:
because if X is greater than -2 then it is -1 because it is the closest to 0 that is why it is -1 > -2 even though you may think that -2 is greater than -1 it's not
well when thinking of gravity you have to think of the size and mass of the object so,
The sun (largest and most mass)
Earth
Earth's moon
Discover satellite (cause it's tiny and light compared to the sun!)
Answer:
48 Units
Step-by-step explanation:
Use the Pythagorean theorem to make two right triangles.
Ex= Base is cut in half to make two 9 unit bases
Then count the units from the half point.
Ex= 12 units long
Then use Pythagorean theorem to find one side of the 9-12 right triangle
Ex= 9^2+12^2=c^2
After finding that c=15 units, add all the sides back together
Ex= 18+15+15=48
Are you are saying that the absolute value of negative six times x equals 54? If you are, then the answer is x equals positive or negative 9. To solve, set up two equations, because it is an absolute value question. In the first equation, write -6x=54. Divide by -6 to get -9. That is just one of two answers. In the second equation, write 6x=54. Divide 54 by 6 to get positive 9. Your answer is positive and negative 9.
