The gym has a total of 25 treadmills and stationary bikes. there are seven more stationary bikes than treadmills.

Rudik [331]

The system of equations is $t+b=25\\b=t+7$

Step-by-step explanation:

We can answer this question as follows.

First of all, we call:

t = number of treadmills

b = number of stationary bikes

The two conditions that we have can be translated into equations as follows:

- The gym has a total of 25 treadmills and stationary bikes:

$t+b=25$

- There are seven more stationary bikes than treadmills:

$b=t+7$

So the system of equations to solve is

$t+b=25\\b=t+7$

We now solve it in the following way: first, we rewrite the second equation by bringing t on the left side,

$t+b=25\\b-t=7$

Now we add the 1st equation to the 2nd equation:

$(t+b)+(b-t)=25+7\\t+b+b-t=32\\2b=32\\b=\frac{32}{2}=16$

And therefore,

$t+b=25\\t+16=25\\t=25-16=9$

So, there are 16 stationary bikes and 9 treadmills.

The quotient of the opposite of a number squared and three

Mars2501 [29]

Answer:

"The quotient of the opposite of a number squared and 3"

Take "the opposite of a number squared" and call it y.

So you get "The quotient of y and 3"

This is y/3.

Now what is y? "The opposite of a number squared"

Take "The opposite of a number" and call it z.

So y is "z squared"

Replacing y, we get z^2 / 3

But what is z? "The opposite of a number"

Call "a number" x.

The opposite of x is -x.

So z is "-x"

Replacing z, we get (-x)^2 / 3
