Step-by-step explanation:
yo sup??
as mentioned earlier XUY is simply the summation of all the unique elements of X and Y
S=XUY
={-1,0,1,2,5}
Therefore your answer is option 1 ie
1.{-1,0,1,2,5}
Hope this helps.
For twice a number we can use the variable x
For four times a number we can use the variable c
4c - 2x + 15
I believe this is correct although I'm not 100% sure
An equilateral triangle have 3 congruent sides.
Divide the total (15x +3) by 3
(15x + 3)/3 = 5x + 1
Each side's length is 5x + 1
hope this helps
Answer:
1. m=1/2
2. x=4/7
3. t=4
4. y=5
Step-by-step explanation:
1. 5m+4=7m+6
5m-7m=6-5
2m=1
m=1/2
2. -5x+3=2x-1
-5x-2x=-1-3
-7x=-4
x= -4/-7= 4/7
3. 5t-3=3t+5
5t-3t=5+3
2t=8
t=8/2= 4
4. 53y-55= 42y
53y-42y=55
11y=55
y=55/11=5
hope it helps!
