Exact value of y is
.
Answer: 18
Step-by-step explanation:
The circumference formula is C= 2
r
r being the radius, so you can just plug in.
C= 2
(9) = 18
Answer:
3x-5
Step-by-step explanation:
(6x+5)-(3x+10) = 6x+5-3x-10
= 3x-5
When using substitution, we are imputing an equation in place of a variable to eliminate one of the variables in the equation so that we can solve for the remaining variable.
For this example, we will be plugging in (-4y+12) wherever "x" is in the other equation.
3/4 x -5y = 7
3/4(-4y+12) -5y =7
((3/4)(-4y))+((3/4)12)-5y=7
-3y+9-5y=7
-8y= -2
y=(1/4)
Now find "x" by plugging in the y-value.
x=(-4*(1/4))+12
x= -1 +12
x=11
