Answer:
x = 13/8
Step-by-step explanation:
sqrt(8x-4) +8 = 11
Subtract 8 from each side
sqrt(8x-4) +8-8 = 11-8
sqrt(8x-4) =3
Square each side
(sqrt(8x-4))^2 =3^2
8x-4 = 9
Add 4 to each side
8x-4+4 = 9+4
8x = 13
Divide by 8
8x/8 = 13/8
x = 13/8
Correct answer is option D.The solution is listed below
Answer:
The Distributive Property states that when a number in parentheses is next to a number, you distribute the number outside of the parentheses and multiply by each of the numbers in parentheses.
5(10+x)=5(10)+5(x)=50+5x

On the right side, there are
• 2•2 = 4 atoms of Nb
• 2•5 = 10 atoms of O
so among the reactants on the left, the reaction is balanced as
4 Nb + 5 O₂ → 2 Nb₂O₅
Answer:
11/20
Step-by-step explanation:
5 cents is worth $0.05.
A quarter is worth $0.25.
A dime is worth $0.10
A nickel is worth $0.05
A penny is worth $0.01
In total there are 40 coins in the jar.
The coins that are worth more than $0.05 dollars are the dimes and quarters, so there are 22 coins worth more than $0.05.
Therefore, the probability of of picking a coin worth more than 5 cents is:
22 / 40 = 11/20
