3*x=3x
3*-5=15
you just distribute the 3 to both values in the parenthesis.
so then we have
17=3x-15+8
simplify
17=3x-23
add 23 to both sides
40=3x
divide both sides by 3
x=13 1/3
Answer:
The answer is 60
Step-by-step explanation:
It is 60 because x=2,so 9(2)+42=60
I don't know what you mean by factors, but the quadratic equation of m^2 - 12m + 20 can be simplified to (m - 10)(m - 2).
Hope this helps!
Answer:
9 meters
Step-by-step explanation:
I don't know step by step if jts wrong tell me.
Singer A
80+14.25h
Singer B
92 +12.55 h
set them equal
80+14.25h= 92 +12.55 h
subtract 12.55h from each side
80 + 1.7 h = 92
subtract 80 from each side
1.7 h =12
divide by 1.7
h =7.0588
h = 7.1 hours
