How you write 8.216 in scientific notation; 8.216 * 10 ^ 3
10 ^ 3 = 10 to the 3rd power.
Hey there!
Let's create a systems of equations using x and y.
4x+3y=15
3x-2y=7
We need to solve this using elimination. First, we need to multiply the first equation by 2/3 so that we can cancel out the y's when combining our equations.
2 2/3x+2y=10
3x-2y=7
Now we combine the equations...
5 2/3x=17
x=3
Now we can plug our x into the first equation to find y.
12+3y=15
y=1
Our numbers are 3 and 1.
I hope this helps!

Answer
![12b^{2} \sqrt[3]{2a}](https://tex.z-dn.net/?f=12b%5E%7B2%7D%20%5Csqrt%5B3%5D%7B2a%7D)
Step-by-step explanation:
It would be t=0.8, mainly bc you subtract two from six , that reduces it to four
then you divide four by five and it should give you your answer
and to chack your work put .8 where t was and solve
