she walked 12 and a half meter every day 12.5
Solve for x. Show each step of the solution.
4(8 – x) + 36 = 102 – 2(3x + 24)
Solve the inequality for x. Show each step of the solution.
12x >9(2x- 3) - 15
Answer:
The length of the badminton court is 44 feet.
Hoped this helped, have a nice day!
x=quantity of days
$38.00+$2.75x=$31.75+$4.00x
We can cancel all $...
38.00+2.75x=31.75+4.00x
It is just as important to cancel symbols as numbers.
Next, we isolate x.
We will begin by subtracting 31.75 from both sides...
-31.75+38.00+2.75x=4.00x
6.25+2.75x=4.00x
Then, we will divide both sides by 4.00...
(6.25/4.00)+((2.75x)/4.00)=(4.00x)/4.00
1.56+0.69x=x
Then, we will subtract 0.69x from both sides...
-0.69x+1.56+0.69x=x-0.69x
1.56=0.31x
Then, we will divide both sides by 0.31...
1.56/0.31=(0.31x)/0.31
5=x
Let's check our numbers...
The original equation was...
$38.00+$2.75x=$31.75+$4.00x
38.00+2.75(5)=31.75+4.00(5)
38.00+13.75=31.75+20.00
51.75=51.75
Answer:
The exponential growth model is given by this general expression:

And the exponential model decay model is given by:

Where a the initial amount r the growth factor of rate anf t the time.
The reason with we need to add 1+r in the base of the model is because each period of time
we have an increase of the initial amount by a factor of (1+r) so after n periods we will have (1+r)^n times the initial amount.
Step-by-step explanation:
In general an exponential model is given by this formula:

Where:
a = the constant, b = the base and x x the exponent.
