Answer:
Let X be the number.
Twice the number would be 2x
The difference between the two, would be subtraction, so you would subtract 4 from 2x
The equation becomes 2x-4 = 16
Now solve for x:
2x-4 = 16
Add 4 to each side:
2x = 20
Divide both sides by 2:
x = 20/2
x = 10
The number is 10.
275,000 km
The moons A, B, C form a right triangle with AC forming a hypotenuse with the diameter of the planet and the distance of both moons from the surface. So add A to the surface, plus the diameter of the planet, plus surface to c.
115000+45000+115000 = 275000
Answer:
A function is a relation in which each input has only one output.
In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
The answer is 117/8 and that is simplified decimal form is. 14.625
First the left fraction 3 x 8=24+3=27 so it is 27/8
Then the right 4 x 3=12+1=13
27 x 13=351
8 x 3=24
351/24
Answer:
No solution.
Step-by-step explanation:
8x - 4 = 2(4x - 4)
8x - 4 = 8x - 8
-4 = -8
-4 ≠ -8
