Step-by-step explanation:
246(.03)= 7.38
246+7.38= $253.38
Answer:
19.80
Step-by-step explanation:
tan 22= 8/x
tan 22 = 8/x
x = 8/tan 22
x = 19.80
Answer:
170
Step-by-step explanation:
Answer:
1st number: 20
2nd number: 25
3rd number: 75
Step-by-step explanation:
x + y + z = 120
x = y - 5
z = 3y
plug that in!
(y-5) + y + (3y) = 120
remove the parenthesis (I used them to show you what I was replacing), and add like terms.
5y - 5 = 120
move -5 to the other side
5y = 120 + 5
5y = 125
divide both sides by 5
y = 25
now that you have one number, use the equations from before to solve for the rest!
x = (25) - 5
z = 3(25)
_____________________________________________________
x = 20
y = 25
z = 75
Hi,
Roots are 2, -1,-3.So y=(x-3)(x+1)(x+3)
