Turn equation around:
7u-9-12u=26
Combine like terms:
-12u+7u=-5u
This turns equation into:
-5u-9=26
Add -9 to both sides:
-5u-9=26
+9=+9 - and + cancel out
-5u=35
Divide by -5 to get “u” by itself:
-5u=35
———— -5 And -5 cancel making
-5 =-5 “u” By itself
u= -7
Hope this helps!
Answer:
9 just find the Greatest common multiple
Answer:
1000 rounded to the nearest ten is:
1000
Step-by-step explanation:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
Answer:
s = 
m
Step-by-step explanation:
Given s varies directly with m then the equation relating them is
s = km ← k is the constant of variation
To find k use the condition s = 9 when m = 30 , thus
9 = 30k ( divide both sides by 30 )
k = 
=
s = m ← equation of variation
