Find multiples of 30 and 40:
30: 30, 60, 90, 120, 150
40: 40, 80, 120, 160
The least common multiple is 120, so every 120 minutes they willl both ring.
1 hour = 60 minutes:
120/60 = 2 hours.
The bells ring together every 2 hours.
8 + 2 = 10 am
10 + = 12pm
12 + 2 = 2 pm
The bells will ring together at am, 12 pm and 2 pm.
(1) -1.79, 2 1/4, 2.54 , -4
negative -> positive
reorder: -4. -1.79, 2 1/4 (or 2.25), 2.54
(2) -x
The larger x is the smaller the value
-$40.75<-$25.20
BUT the larger after the minus the more you owe so Renae owes more.

sorry idk
(4)
78F-x=70F
|x|=8*F
Answer: 110 -10x
Step-by-step explanation:
You do pemdas
So 11•10 = 110
Then -10•x = -10x
And then you get
110-10x
I think it's b
Hope I could help
Answer:
x = 2
Step-by-step explanation:
Simplify both sides of the equation.
−20 = − 4x − 6x
−20 = −4x − 6x
−20 = (−4x − 6x)(Combine Like Terms)
−20 = −10x
Flip the equation.
−10x = −20
Divide both sides by -10.
-10x/-10 = -20/-10
x = 2
