sattari [20]

If Anne gave birth to four males and four females, and they all gave birth the same way again, they would have eight males, but if it were to happen again, there would be 12 males and 12 females in total if you don't count all of the females giving birth EACH to four males and four females. Otherwise it would be 40 males, and 40 females.

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.
