Answer:
Step-by-step explanation:
2x - 7 + 2x - 5 + 2x - 3 + 2x - 1 + 2x + 3 + 2x + 5 + 2x + 7 Combine like terms
16x / 8 = 48
2x = 48
x = 24
The range is defined as the largest number - the smallest number
The range is between 2x - 7 and 2x + 7
x = 24
The smallest number is 48 - 7 = 41
The largest number is 48 + 7 = 55
The range = 55 - 41 = 14
Why was the 2 in front of the x needed? It was to make sure that I could create an odd number.
Why did I subtract an odd number? That was to make sure that I could create odd numbers.
Why did I start with 2x - 7 and end up 8 terms later at 2x + 7?
So the numbers would cancel and I'd only be left with x's.
Answer:
(-∞, 6) or [5, ∞)
Step-by-step explanation:
subtract 3
5x< -30 or 3x ≥ 15 .
divide
x < 6 or x ≥ 5
Common ratio = -25/-125 = 1/5 answer
Answer:
x=20
4=140
1=40
Step-by-step explanation:
7x=2×+100
5×=100
×=20
4=7(20)=140
1=180-140=40
Answer:
x times 3 equals y
Step-by-step explanation:
If it doesn’t provide the amount of students, it needs to be written as an equation. x will be the amount of students and y would be the amount of pencils each person gets. So, you need to multiply x with 3 because then it will show the result, which is y.
