Step-by-step explanation:
1)
Let x=larger number
y=smaller number
x+y=59
x-y=13
Now adding these two equations we get
2x=72
x=36
Now as x-y=13
y=x-13=36-13=23
y=23
Therefore the larger number is 36 and the smaller number is 23
(or else u could also write)
The numbers are 36 and 23
---------------------------------------------
2)
Let x=first number
y=Second number
x+y=15
2x-y=6
Now adding these two equations we get
3x=21
x=7
Now as x+y=15,
y=15-x=15-7=8
y=8
Therefore the first number is 7 and the second number is 8
-------------------------------------------
3)
Let x=Larger number
y=smaller number
x-y=3
x-3y=-11
Now on subtracting these two equations we get
2y=14
y=7
Now as x-y=3,
x=y+3=7+3=10
x=10
Therefore the larger number is 10 and the smaller number is 7
Answer:
chromosomes are of two in human x and y but the mother has only x chromosomes when xand x meet then baby girl is born and when x and y meet then baby boy is born.Genes is the properties which are present in all living organisms.The full form of DNA is deoxy ribonucleic acid.It is the properties which carries the similarities of both mother and father to a new generation.

I just learned this in class lol
Find the area of all the sides.
This cubiod has 6 sides.
6 x 5 = 30
6 x 5 = 30
4 x 5 = 20
4 x 5 = 20
6 x 4 = 24
6 x 4 = 24
30 + 30 + 20 + 20 + 24 + 24 = 148
Thefore, the surface area of this cuboid is 148.
Hope this helps! If it did, please mark it as brainliest! It would help a lot! Thanks! :D
To get angle Y, you have to do 90 - 27 to get the other angle in the triangle and you get 63. Then you do 180 - (63+51) which is 66.
Angle Y = 66
