Fourteen less then twice a number is 154. Find the number.

84

Step-by-step explanation:

Let x be the number.

2x-14=154

2x=168

x=168/2=84

The number is 84

Step-by-step explanation:

Assume the unknown number is x

The question interprets to 2x - 14 = 154

Collecting like times, we have 2x = 154 + 14

2x = 168 divide both sides by 2, which is the coefficient of x

x = 168/2

x = 84

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
