Answer:

A. 1,825 days

B. 56 days

C. 1 week

D.  1,209,600 seconds

E. 43,200 seconds

F. 2 hours

Step-by-step explanation:

A. 1 year = 365 days, then

5 years = 5\cdot 365 days = 1,825 days.

B. 1 week = 7 days, then

8 weeks = 8\cdot 7 days = 56 days.

C. 7 days = 1 week.

D. 1 hour = 3,600 seconds, then

336 hours = 336\cdot 3,600 seconds = 1,209,600 seconds.

E 12 hours = 12\cdot 3,600 seconds = 43,200 seconds.

F. 3,600 seconds = 1 hour, then

7,200 seconds = \dfrac{7,200}{3,600} hours = 2 hours.

Debora [2.8K]

Answer:

x =  2.

Step-by-step explanation:

5[3(x + 4) − 2(1 − x)] − x − 15 = 14x + 55

5[3x + 12 - 2 + 2x] - x - 15 = 14x + 55

5[5x + 10] - x - 15 = 14x + 55

25x + 50  - x - 15 = 14x + 55     Now we subtract 14x from both sides:

25x + 50  - x - 15  - 14x = 14x - 14x + 55

10x + 50 - 15 = 55 Now we subtract  50, add 15 to both sides:

10x + 50 - 50 - 15 + 15 = 55 - 50 + 15    

10x =  20

x = 2.

Y&gt;-3x +3<br> y≥ 2x-2<br> O (1,0)<br> O (-1,1)<br> O(2,2)<br> (0,3)
Ainat [17]

Answer:

(1,0)

Step-by-step explanation:

y>-3x +3

y≥ 2x-2

If we plot these two inequalities, we can see where the lines intersect,  See attached graph.

They intersect at (1,0)

We can also do this mathematically:

  y>-3x +3

<u>- (y≥ 2x-2)</u>

0 \geq -5x + 5

5x \geq 5

x \geq 1

If x = 1:

y≥ 2x-2

y≥ 2(1)-2

y≥ 0

(x,y) = (1,0)

Simplify the expression 13. 8+(-11. 5). Use pencil and paper. How are 13. 8 + (-11. 5) and (-13. 8) +11. 5
VashaNatasha [74]

On simplifying the expression 13.8+ (-11.5) , we get 2.3 . And additions

13.8 + (-11.5) and (-13.8) +  11.5 are numbers will same value and opposite sign.

<h3>What are rules for adding a positive and a negative number?</h3>

For adding a negative and a positive number, use the sign of the larger number and subtract.

For example: (–8) + 2 = -6

Given that we have to solve 13.8 + (-11.5) = 13.8-11.5 (we subtract smaller no from larger and will use the sign of lager number that is + here)

13.8+(-11.5) = 13.8-11.5 =2.3

13.8+(-11.5) simply means that 13.8 -11.5 which is subtraction of 11.5 from 13.8

but (-13.8) +  11.5 = -13.8 +11.5  =  -( 13.8 -11.5) [taking -1  common from the expression]

Therefore , -13.8 + 11.5 has same value as 13.8- 11.5 but opposite  in sign.
