Step 1: Simplify both sides of the equation.
3(x−5)−5=23
(3)(x)+(3)(−5)+−5=23(Distribute)
3x+−15+−5=23
(3x)+(−15+−5)=23(Combine Like Terms)
3x+−20=23
3x−20=23
Step 2: Add 20 to both sides.
3x−20+20=23+20
3x=43
Step 3: Divide both sides by 3.
3x
/3 = 43
/3

Answer:
42 + 42 + z = 180
Step-by-step explanation:
Note that:
Base angles in an isosceles triangle are equal in measure.
The sum of angles in a triangle is 180°.
Thus, the equation would be
42 + 42 + z = 180

Answer:
The domain of the function in interval notation is ![[0,112]](https://tex.z-dn.net/?f=%5B0%2C112%5D)
Step-by-step explanation:
Let
h(t) -----> the heart rate of a runner
t ----> the time in minutes
we know that
The runner completed the 10 mile run in 112 minutes
112 minutes is the maximum time of the domain
so
![0\ min \leq t \leq 112\ min](https://tex.z-dn.net/?f=0%5C%20min%20%5Cleq%20t%20%5Cleq%20112%5C%20min)
The domain is all real numbers greater than or equal to 0 minutes and less than or equal to 112 minutes
In interval notation the domain is
![[0,112]](https://tex.z-dn.net/?f=%5B0%2C112%5D)
You would make 1200 because of taxes. That all I know sorry
