Answer:
Option 1.
The solution set is: {n|n is a real number, n≥3}
Step-by-step explanation:
1. You must read carefully the information given in the problem: "One less than twice a number" indicates that you must write a number 
multiplied by 2 and subtract 1 from this term, as following:
2. "is not less than five" indicates that the result must be equal or greater than 5. Then, you obtain the following expression:
3. Now, you can solve for . Then, you obtain:
4. Then, the solution set is: {n|n is a real number, n≥3}.
5. The correct plot on the number line must show a circle on 3 (You must fill in the circle if the sign is 
or
) with a line from that circle to the right.
5. Therefore, the answer is the first option.
X=750+125.75x
subtract to variable (x) on one side
x-125.75x=750+125.75x-125.75x
-124.75x=750
divide -124.75 to get variable (x) by itself
-124.75x/-124.75=750/-124.75
x=-3000/499
or
x=-6 6/499
or
x=-6.01202
1080/90 = 12
2250/150 = 15
There would be a higher rate on the 2250 labels on 150 sheets.
I’m veryyy confused can yu show a pic
<span>
y = 7 + 3/5
y = 35/5 + 3/5
y = 38/5
y = 2*(38/5)
y = 76/10
---
lunch time:
z = 1/2
z = 5*(1/2)
z = 5/10
---
time switching classes:
w = 7/10
---
y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (76/10 - 5/10 - 7/10)/6
x = (76 - 5 - 7)/(10*6)
x = (64)/(10*6)
x = (2*2*2*2*2*2)/(2*5*2*3)
x = (2*2*2*2)/(5*3)
x = 16/15
x = 1.0666666666
---
check:
y = 7 + 3/5
y = 7.6
z = 1/2
z = 0.5
w = 7/10
w = 0.7
y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (7.6 - 0.5 - 0.7)/6
x = 1.0666666666
