Answer:
![t = \frac{100}{r} [\frac{D}{C} - 1]](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B100%7D%7Br%7D%20%5B%5Cfrac%7BD%7D%7BC%7D%20-%201%5D)
Step-by-step explanation:
Assume that the deposited amount C dollars earn r% simple interest annually.
If after t years the deposited amount C dollars grows to D dollars, then we are asked to write a relation using the given terms to calculate t.
Now, using the formula of simple interest we can write
⇒ 
⇒ 
⇒
So, this is the expression for t. (Answer)
Answer:
x= 17
Step-by-step explanation:
5x-7=3x+27
move 3x to other side by doing the oppostie (subtracting 3x)
5x-7-3x=27
2x-7=27
move -7 to other side by adding it (to the other side)
2x= 7+27
2x= 34
divide by 2 (on both sides) to get x by itself
2x/2=34/2
x= 17
Answer:
45.8
Step-by-step explanation:
Say the number Malachy was thinking of is <em>x</em>.
Doubling it gives 2x, which we see also equals 91.6. Set these equal to each other:
2x = 91.6
To solve, we divide both sides by 2 and get x = 45.8, which is our answer.
