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:
x = a - 5
Step-by-step explanation:
3x - a = 2x - 5 ( subtract 2x from both sides )
x - a = = 5 ( add a to both sides )
x = a - 5
We notice that the common ratio of teh sequence is 10, and that the first term is -0.56, then the recursive formula is:
Answer:
the equation ( in t(n) form) is t(n)= 325(1.04) to the 12th exponent. otherwise the answer is 520.34 if you round up the half cent.
Step-by-step explanation:
325 is the starting value, or figure 0. 1.04 is the multiplier because it is growing buy .04 and you need to add in the 1 otherwise it'd decrease by 96% each time.
