18a+15
making a subject of formular
a=18-15
=3
Step-by-step explanation:
y=-2x+1 so we say (-2x+1)
we flip the equation by saying
-2x+1 -1=y+-1
-2x=y-1
Divide both sides by -2
-2÷-1 = y-1÷-2
so x=-1÷2 y=+1÷2

Answer:
The diameter is 361 units
Step-by-step explanation:
The formula for circumference of a circle is given by
C = pi *d
We know the circumference = 1133.54 and pi is approximated by 3.14
1133.54 = 3.14 *d
Divide each side by 3.14
1133.54/3.14 = d*3.14/3.14
361=d
The diameter is 361 units
