Answer:
2,000
Step-by-step explanation:
We need to figure out how much string would be left, after taking away the first two pieces.
We know that the first piece is 20 inches long, so we can say that there is 52-20 inches left, or 32 inches.
The second piece is between 12 and 18 inches, meaning that there would be between 32-12 and 32-18 inches left for the third piece, or 20 and 14 inches. This means that the third piece would be at least 14 inches long, but no more than 20, since we don’t have more string than that (20+12+20=52, and 20+14+18=52)
So we can say that x is greater or equal to 14, but less than or equal to 20, or:
14<=x<=20 (“<=“ is written like a normal “<“ sign with a line _ right under it)
Answer:



Step-by-step explanation:
The three salespeople for a local advertising firm are sara, Kenny and Leila.
Sara sold total ads = $3350
Kenny sold total ads = $1368
Leila sold total ads = $456
First we calculate total sale of all three = 3350 + 1368 + 456 = $5174
We need to find fraction of total sale with each person sell.



The area of a square is s•s.
A= 6.25•6.25
A= 39.0625
Rounded= 39.06 square feet
(I'm assuming rounding to the significant digits means rounding to the hundredths since 6.25 is rounded to the hundredths.)
3x + 9 + 4x + x simplifies to 8x + 9
y = mx + b: m is slope, b is y-intercept
no solutions: 8x + 8
(no solution from same slope and different y-intercept)
one solution: 4x + 1
(different slope needed)
infinitely many: 8x + 9
(same y-intercept, same slope_
