Do you have the distance from the Earth to Saturn?
Answer: 3x
Step-by-step explanation:
Solve Systems of Equations:
x + 12y = 7; x - y = 7 =======> x = 7, and y = 0
Step 1: I will try to solve your System of Equation:
x + 12y = 7; x - y = 7
Solve:
x + 12y = 7x for x:
x + 12y + -12y = 7 + -12y (Add --12y both sides):
x = -12y + 7
Substitute:
-12y + 7 for x in x - y = 7
x - y = 7
-12y + 7 - y = 7
-13y + 7 = 7 (Simplify both sides):
-13y + 7 + -7 = 7 + -7 (Add -7 both sides):
-13y = 0
-13y / -13 = 0 / -13 (Divide both sides by -13):
y = 0
Substitute:
0 for y in x = -12y + 7
x = -12y + 7
x = ( -12 )(0 ) + 7
x = 7 (Simplify both sides of Equations:):
Therefore, Answers, x = 7, and y = 0

We will find the greatest common factor of numbers 126 and 588
It 42
Answer:
9.4 inches
Step-by-step explanation:
The triangle formed is aright angled triangle with the right angle between the length and width of the paper cut hence the diagonal represents the hypotenuse side.
Recall that Pythagoras theorem states that
a^2 + b^2 = c^2 where c is the hypotenuse side and a, b are the opposite and adjacent sides
Hence
8^2 + 5^2 = c^2
c^2 = 64 + 25
= 89
Finding the roots of both sides
c = 9.433981132
To the nearest tenth
c = 9.4 inches
