Answer:
Step-by-step explanation:
c. 0.875
140,000,000x0.25=35,000,000
35,000,000/40,000,000=0.875
0.0000021 you need to divide 2.1 by 10^6
X=2
subtract 5x on both sides
-2x=-4
divide by -1 on both sides
2x=4
divide by 2 on both sides
x= 2
320 times .19t
t being the number of years
3y^-4/3 x 2 3/y
Write in exponential form with the base of y
= 3y^-4/3 x 2y^1/3
Calculate the product
= 6y^-1
Any expression raised to the power of equals its reciprocal
= 6 x 1/y
Calculate the product
= 6/y
