Answer:
No solutions
Step-by-step explanation:
2(x+1)=2x+5
Expand the parentheses:
2x+2=2x+5
Subtract 2x from both sides:
2=5
Since this is not true, this equation has no solutions. Hope this helps!
Answer: 75%
Step-by-step explanation:
Height given :
69, 62, 73, 67, 63, 65, 73, 71, 70, 66, 59, 75
The total number of height given = 12
The height less than 73 are 69 , 62, 67 ,63 , 65 , 71 , 70 , 66 , 59
The total number of heights less than 73 = 9
Therefore : the percentage of these students who are shorter than 73 inches = total number of students shorter than 73/ total number of height x 100
= 9/12 x 100
= 75%
No srry if I wrong .......
Answer:
(4, 5)
Step-by-step explanation:
5x + y = 25
-3x + 2y = -2
5x + y = 25
y = 25 - 5x
-3x + 2 * (25 - 5x) = -2
-3x + 50 - 10x = -2
-13x = -52
x = 4
5 * 4 + y = 25
20 + y = 25
y = 5
Solution: (4, 5)
