Answer: is x = -8
this is how i got it ______
6 x - 3 - 11 - 8 x = 2
(simplify both sides and combine like terms)
(6x + -8x ) + ( -3 + -11) = 2
- 2x + -14 = 2
-2x - 14 = 2
( then you add 14 to both sides)
- 2x - 14 = 2
+14 +14
-2x = 16
( then you divide both sides by -2)
-2x / -2 = 16/ -2
x = -8
ta da!! happy to help!
it made it here. this is for the second one.
( first, we subtract 8n from both sides)
13n + 26 = 8n - 29
-8n -8n
5n + 26 = -29
( then we subtract 26 from both sides)
5n + 26 = -29
- 26 -26
5n = - 55
(after that we divide both sides by 5, we do this to make n alone )
5n/ 5 = -55/ 5
n = -11
Answer:
<em>The cost of a gallon of milk changed 31%</em>
Step-by-step explanation:
<u>Percent Change</u>
Is the difference between two values of the same variable in different times or conditions, expressed as a percentage of the original value.
The formula is:
Where
v1 = original value
v2 = final value
The gallon of milk cost v1=$2.90 in 2002 and v2=$3.80 in 2018. The percent change is:
Pc = 31%
The cost of a gallon of milk changed 31%
Solve : 9x-14 = 0
Add 14 to both sides of the equation
9x = 14
Divide both sides of the equation by 9:
x = 14/9
Answer:
t = 8.2 sec
Step-by-step explanation:
the ball will move with uniform deceleration due to gravity until it reaches the highest point at which v = 0 then will change its direction and continue with uniform acceleration until it hits the ground.
the time the ball takes to reach the highest point equals the time it takes to return to the ground again.
to calculate the total time, we calculate the first half then multiply it by 2
we use the first equation because we have all the variables except time
v = 0 , u = 40 , a = -9.8
0 = 40 - 9.8t
t = 4.1 sec
total time = 4.1 x 2 = 8.2 sec
