Total amount saved in 1st case :
![S_1=400+20t_1](https://tex.z-dn.net/?f=S_1%3D400%2B20t_1)
Total amount saved in 2nd case :
![S_2=100+40t_2](https://tex.z-dn.net/?f=S_2%3D100%2B40t_2)
( Here
are number of months )
Let, after x months the amount saved in both cases is same.
So,
![S_2=S_1\\\\100+40x=400+20x\\\\20x = 300\\\\x = 15\ months](https://tex.z-dn.net/?f=S_2%3DS_1%5C%5C%5C%5C100%2B40x%3D400%2B20x%5C%5C%5C%5C20x%20%3D%20300%5C%5C%5C%5Cx%20%3D%2015%5C%20months)
Amount saved :
![S_1=400+20(15) =\$ 700](https://tex.z-dn.net/?f=S_1%3D400%2B20%2815%29%20%3D%5C%24%20700)
![S_2=100+40( 15)= \$700](https://tex.z-dn.net/?f=S_2%3D100%2B40%28%2015%29%3D%20%5C%24700)
Hence, this is the required solution.
Answer:
x+3
Step-by-step explanation:
notice how each time you add three
how did I khew that we add 3?
simply by substracting a term from the next one
so 8-5= 3
(3x + 15) + (x + 7) = 94
4x + 22 = 94
4x = 94 - 22
4x = 72
x = 18
You place it inside x + 7
So, 18 + 7 = 25
Angle CBD = 25
Answer: 15
Step-by-step explanation:
It's an Isosceles triangle meaning both sides are congruent (same)
So with that in mind we can make an equation making them equal to each other to find X.
3x = 5x - 30
Subtract 5x from both sides
-2x = -30
We can't have a negative x so we divide x by a negative
x = 15
