It decreases
The further two objects are, the gravitational attraction decreases and the closer two objects are, the gravitational attraction increases
Answer:
x=22
Step-by-step explanation:
Reorder the terms:
3(-4 + x) = 2(x + 5)
(-4 * 3 + x * 3) = 2(x + 5)
(-12 + 3x) = 2(x + 5)
Reorder the terms:
-12 + 3x = 2(5 + x)
-12 + 3x = (5 * 2 + x * 2)
-12 + 3x = (10 + 2x)
Solving
-12 + 3x = 10 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-12 + 3x + -2x = 10 + 2x + -2x
Combine like terms: 3x + -2x = 1x
-12 + 1x = 10 + 2x + -2x
Combine like terms: 2x + -2x = 0
-12 + 1x = 10 + 0
-12 + 1x = 10
Add '12' to each side of the equation.
-12 + 12 + 1x = 10 + 12
Combine like terms: -12 + 12 = 0
0 + 1x = 10 + 12
1x = 10 + 12
Combine like terms: 10 + 12 = 22
1x = 22
Divide each side by '1'.
x = 22
Simplifying
x = 22
4x - y = 61
2y = x
substitute x = 2y in first equaation:-
4(2y) - y = 61
7y = 61
y = 61/7
so x = 2 * 61/7 = 122/7
y = 8 5/7 and x = 17 3/7
5/100 = 0.056 sales tax
$12+$26+$125 = $163 total purchases without tax
163*0.056 = 9.128 tax based on how much she bought
$163 + 9.128 = $172.128 total amount she paid.
