Assuming your solving for y:
py+7=6y+q
-6y -7 -6y -7
(p-6)y = q-7
divide both sides by p-6
y=(q-7)/(p-6)

Answer:

The required equation is  y =\frac{(q-7)}{(p-6)}.

Step-by-step explanation:

Consider the provided equation.

py+7=6y+q

We need to simplify the equation and convert it into a linear equation with unknown coefficients.

Subtract 6y from both sides.

py - 6y + 7 = q

Subtract 7 from both sides.

py - 6y = q - 7  

Take y common from left side.

y(p-6) = q-7

 Divide both sides by p-6.

 y =\frac{(q-7)}{(p-6)}

Hence, the required equation is  y =\frac{(q-7)}{(p-6)}.

Suppose the population of a town is 8,200 and is growing 4% each year, what is the population expected to be in 10 years
miv72 [106K]

Answer:

12,138 people

Step-by-step explanation:

Create an equation using the basic exponential growth equation:

y = a(1 + r)^t, where a is the initial amount, r is the growth rate as a decimal, and t is the amount of time in years.

Plug in the values we know

y = a(1 + r)^t

y = 8200(1 + 0.04)^10

y = 8200(1.04)^10

= 12,138 people

What is th result of converting 20 ounces into pounds?
Harrizon [31]
Hello!

The Correct Answer would be:

"1.25 Pounds"

Why? Well:

1 ounce (oz) is equal to 0.0625 pounds (lb).

1 oz = (1/16) lb = 0.0625 lb

The mass m in pounds (lb) is equal to the mass m in ounces (oz) divided by 16:

m(lb) = m(oz) / 16


So as Result, The Answer is 1.25 Pounds.


Hope this Helps! Have A Wonderful Day! :)
