Answer:
2x+ 2.1 = 7.5
x=2.7
Step-by-step explanation:
The perimeter of an isosceles triangle with sides x and y is
2x+y = P
I put y as the single side since the question said y is the shortest side. It should say shorter sides if the two sides with the same length are smaller than the third.
We know y =2.1 and P = 7.5
Substituting these values in, we get
2x+ 2.1 = 7.5
Subtract 2.1 from each side
2x+2.1 -2.1 = 7.5 -2.1
2x= 5.4
Divide each side by 2
2x/2 = 5.4/2
x = 2.7 m
Answer: 0
Step-by-step explanation:
first you distribute the negative which gives you 7-3-4 which equals 0
Answer:
Median = 45
Step-by-step explanation:
Since the given data set is already in ascending order, we we just have to find the middle most number of the data set:
There are 2 middle numbers 40 and 50, so to find the middle most number find their average:
(40 + 50) / 2 = 45
Median = 45
Hope this helps!
I would answer but I don’t see the options to choose... can you tell me?
14/12=1 and 2/12= 1 and 1/6
31/10= 3 and 1/10
