Answer:
148
Step-by-step explanation:
Average = sum of numbers /total numbers
let x = 5th number
123.2 = (118+ 128 + 124,+ 98 + x) / 5
123.2 = (468 + x) / 5
Multiply both sides by 5
616 = 468 + x
x = 148
Answer:
26
Step-by-step explanation:
Since the input is -4, x = -4. The equation then is y = -7(-4) -2
A negative times a negative is a positive, so -7 times -4 is 28.
Now the equation reads y = 28 - 2
Then obviously you just subtract the two and then you get 26.
Answer:
x=9/4
Step-by-step explanation:
You just have to make 36/10 into 3 6/10. After that, it would become 3.6
The LCM is of 128 and 32 is 128
