Answer:
See diagram and explanation
Step-by-step explanation:
A number on the right is greater than a number on the left on the number line.
Mark numbers 2 and 3 on number line (number 3 is to the right from number 2, because 3 > 2).
Divide the unit segment between numbers 2 and 3 into 8 equal parts (this segment is the unit segment because the distance between 3 and 2 is 1).
Each such part represents 
of the segment.
Mark the number 
next to the right from 2 (you have to take 2 and 1/8).
3gallons/ 2,100 ft = 7galloons/ X
3X= (2,100)(7)
X= (2,100)(7)/ 3
X= 4,900 ft^2
Answer:
2 solutions (- 4, 4 ) and (- 1, 1 )
Step-by-step explanation:
The solutions are at the points of intersection of the straight line and the curve.
There are 2 points of intersection , thus 2 solutions
The points of intersection are (- 4, 4 ) and (- 1, 1 ) ← solutions
Answer:
8 pen : 26
15 pen : 60
Step-by-step explanation:
5 pen = 20
Times both sides by 2
10 pen = 40
add 5 pen = 20
15 pen = 60
Divide 10 by 5
2 pen = 4
1 pen = 2
Add them together
3 pen = 6
Add 5 pens and 20
8 pen = 26
The vertical lines are absolute values, the number in between them, if negative turns positive.
