Acash register contains only five dollar and ten dollar bills. it contains twice as many five's and tens if the total amount of money is $680 how many tens are in the cash register?

There are 34 Tens and 68 Fives

Step-by-step explanation:

2X*5+X*10=680  

Multiply 2X by 5 to get 10X.

10X+X*10=680  

Multiply X by 10 to get 10X.

10X+10X=680  

Since 10X and 10X are like terms, add 10X to 10X to get 20X.

20X=680  

Divide each term in the equation by 20.

(20X)/(20)=(680)/(20)  

Simplify the left-hand side of the equation by canceling the common factors.

X=(680)/(20)  

Simplify the right-hand side of the equation by simplifying each term.

X=34 tens

68 fives

Prove:  

34*10= 340

68*5= 340

340+340=680

There are 34 tens and 68 fives because 34*5 + 68*10 = 680.

Step-by-step explanation:

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
