Answer:
D) 240 000 cm³
Step-by-step explanation:
V = 100cm×80cm×(80-50)cm
= 8000cm²×30cm
= 240 000 cm³
Answer:
140
Step-by-step explanation:
183-37=146
Answer:
5x(squared)-4x+1
2x(squared)+11xy+14
7x(squared)+7xy+3x-17
Step-by-step explanation:
X = 7/2 and 9 there you go hun
Number of pencils x
number of pens y
3x + y = 10
x ≤ y
Draw the line 3x + y = 10 .[it passes by (0,10) and (-10/3,0)
Draw the line y=x [it passes by (0,0), (1,1), (2,2) etc]
Then the solution is the points with integer x and y, that belong to the segment of the line 3x +y = 10 between the x-axis and the line y=x. Those points are (1,7) , (2,4), (3, 1).
