Answer:
x=-0.625
Step-by-step explanation:
24x+15=0
-15 -15
24x=-15
x=-0.625
Option D: 3.47*10^-7 is the correct answer
Step-by-step explanation:
In order to determine the number written in standard scientific notation, first of all we have to understand how the scientific numbers are written
the scientific numbers are written in the form of:

Here
a is a number between 1 and 10 while the value of n can be only integer (positive or negative)
so,
In the given options:
Option A has a number larger than 10 in place of a so it is not in standard notation
Option B has a number less than 1 in place of a so it is also not in standard notation
Option C has a number larger than 10 in place of a so it is not in standard notation
Option D is in standard scientific notation as 1<3.47<10 and the power of 10 is integer
Hence,
Option D: 3.47*10^-7 is the correct answer

-4/25 is the answer
Hey there!!
Take the cinnamon tea as ' x ' and spice tea as ' y '
10 x + 2y = 19 -------------- ( 1 )
16x + 10y = 44 --------------- ( 2 )
Multiply the first equation by 5
50x + 10y = 95
16x + 10y = 44
Subtract the second equation from the first
34x = 51
x = 51 / 34
x = $1.5
Substitute this in any other equation
15 + 2y = 19
2y = 4
y = 2
Cinnamon = $1.5
Spice tea = $2
Hope helps!
