Answer:
x= -2
Step-by-step explanation:
4x + 2 = 6(-2x - 5)
Distribute
4x+2 = -12x-30
Add 12x to each side
4x+2+12x = -12x-30+12x
16x+2 = -30
Subtract 2 from each side
16x+2-2=-30-2
16x = -32
Divide by 16
16x/16x = -32/16
x = -2
Answer:
Option C) describes something that does not have width or depth
Step-by-step explanation:
We are given the following information in the question:
We may define line as:
- A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions.
- A line is sometimes called a straight line.
- It is demonstrated by arrow on both sides showing that it can be extended on both sides.
- A line can be considered undefined term because it tells us about something that does not have width or depth.
- A lines can extend its length in both side infinitely. It contains arrowheads indicating it can extend.
Thus, the correct option is Option C) describes something that does not have width or depth.
Answer:
120 grams will be left after 180 years.
Step-by-step explanation:
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and its given by

where,
= quantity of the substance remaining
= initial quantity of the substance
= time elapsed
= half life of the substance
From the information given we know that:
- The initial quantity is 480 g,
- The half-life is 90 years,
- 180 years is the time elapsed.
And we want to find how much will be left. For this we use the above formula.

120 grams will be left after 180 years.
