Tim and Rita made the same amount of money one week delivering packages. Each earned a base pay plus a certain amount for each package delivered. Which of the following situations could you model using the equation 250 + 36x = 325 + 28x? Tim's pay was $250, and Rita's pay was $325. Tim also earned $28 per package, and Rita also earned $36 per package.

Tim's pay was $36, and Rita's pay was $28. Tim also earned $325 per package, and Rita also earned $250 per package.

Tim's pay was $36, and Rita's pay was $28. Tim also earned $250 per package, and Rita also earned $325 per package.

Tim's pay was $250, and Rita's pay was $325. Tim also earned $36 per package, and Rita also earned $28 per package.

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.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
