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
The value of n is 10.
Solution:
Given expression:
<u>To solve this expression:</u>
Add 2 on both sides of the expression.
Multiply by 5 on both sides of the expression, we get
4n = 40
Divide by 4 on both sides of the expression, we get
n = 10
Hence the value of n is 10.
It's the 26th term of the sequence.
Hope this helps! :)

X-3y, x=3, y=-2
(3)-3(-2)
(3)+(3*2)
3+6=9
45% is the answer, since u have to multiply the 3% by 15
