What is x if
-10x - 2 = 18

Answers

Answer 1
Answer:

Answer:

x = -2

Step-by-step explanation:

To solve -10x - 2 = 18 for x, you have to do the inverse of each operation, but backward. Since the equation subtracted two last, we have to add (since the opposite of subtraction is addition) 2 first. 18 + 2 = 20, so now we have -10x = 20. This is because -2 + 2 cancels out the -2 (it equals 0).

Then, we have to divide both sides of the equation by -10 to get x by itself.  Since the equation multiplied by -10, we have to do the opposite of multiplication, which is division. (-10x)/(-10) = x because -10 divided by -10 equals 1 and one multiplied by x is 1x, or just x. Now we have x = (20)/(-10) since we have to do the same thing on both sides. A positive divided by a negative is a negative, and 20 divided by 10 is 2, so our answer is negative 2. Therefore, x = -2.

For a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. Whatsize buttonhole is needed for a button with a circumference of 7.38 centimeters? (Use the value of 3.14 to
represent pi.)
A. 2.35 centimeters
B. 1.14 centimeters
C. 5.14 centimeters
D. 3.69 centimeters

Answers

answer is A.2.35cm
c=pid
circumstances is 7.38 cm so
7.38=3.14d
divide both sides by 3.14
7.38/3.14=3.14x/3.14
2.35=×

Simplify the expression. Write the answer using scientific notation.Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles. Suppose a star is 15.8 light-years from Earth. In scientific notation, how many miles away is it?

Answers

we are given with two distances: 5,880,000,000,000 miles and 15.8 light-years. we convert first the light-years distance through the speed of light : 3 x 108 m/s. v = d/t; d = 3x10 8 m/s * 15.8 light years * 31536000 s = 1.4948 x1017 m = 9.28829 x 1013 miles. The difference thus is 8.70029 x 1013 miles
