Answer:
balloons= 9
candles= 8
Step-by-step explanation:
let the number of balloons be x
and candles be y
So
15x+8y=192----------1
x+y=17--------------2
from 2, x= 17-y
put x= 17-y in 1
15( 17-y)+8y=192
255-15y+8y=192
solve for y
-7y=192-255
-7y=-63
x=63/7
x=9
put x= 9 in 1
9+y=17
y= 17-9
y=8.
Add 3x and 2x together to get 5x. Then do 88+108-6 and you get 190. To find x now all you have to do is use 5x+190=360 to get x.
360 -190= 170 now you have 5x=170 divide 170/5 and that will give u the value of x.
Answer:
y=25600
y=100(2)^{2t}
y=252
Step-by-step explanation:
A bacteria culture starts with 100 bacteria and doubles in size every half hour.
![y=100(2)^{2x}](https://tex.z-dn.net/?f=y%3D100%282%29%5E%7B2x%7D)
where x represents the number of hours
(a) t= 4 hours
Plug in 4 for t and find out the number of bacteria y
![y=100(2)^{2 \cdot 4}\\y=25600](https://tex.z-dn.net/?f=y%3D100%282%29%5E%7B2%20%5Ccdot%204%7D%5C%5Cy%3D25600)
25600 bacteria
![y=100(2)^{2t}](https://tex.z-dn.net/?f=y%3D100%282%29%5E%7B2t%7D)
convert 40 seconds into hour
40 divide by 60 =2/3
![y=100(2)^{2\frac{2}{3} }\\y=100(2)^{\frac{4}{3} }\\\\y=252](https://tex.z-dn.net/?f=y%3D100%282%29%5E%7B2%5Cfrac%7B2%7D%7B3%7D%20%7D%5C%5Cy%3D100%282%29%5E%7B%5Cfrac%7B4%7D%7B3%7D%20%7D%5C%5C%5C%5Cy%3D252)
The graph is attached below
1. Add x on both sides of the equation.
2. Subtract 5 from both sides of the equation.
3. Divide both sides of the equation by 3.
