Answer:1) First, add or subtract both sides of the linear equation by the same number.
2) Secondly, multiply or divide both sides of the linear equation by the same number.
3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.
Hello there!
m = 10x - x, solve for x.
First, we need to combine like-terms.
10x - x = 9x.
We now have:
m = 9x
Divide both sides by 9 to solve for x.
x =
I hope this helps!
Answer:
60
Step-by-step explanation:
You would just plug everything in so you get -5(-2-(-5)(-2)) which can be reduced so -5(-12) which is 60
Answer:
1:00 a.m. (and 3:00 a.m., and 5:00 a.m.)
Step-by-step explanation:
The problem is to find the least common multiple (LCM) of the barking intervals. One way to find the LCM is to find the product of the factors of the numbers.
... 5 = 5 . . . . a prime number
... 8 = 2³
... 12 = 2²×3
The factor 2³ is a multiple of the factor 2², so we only need 2³ in our final product.
The LCM is then ...
... 2³×3×5 = 120 . . . . minutes
The dogs will all bark together every 120 minutes (2 hours).
2 hours after 11 p.m. is 1 a.m.
_____
The problem statement doesn't say whether Ms. Li was awakened multiple times. The dogs will bark together again at 3 a.m., 5 a.m. and (possibly) 7 a.m.
