According to your question, there are 2 unknown numbers mentioned.
Let the 2 unknown numbers be represented by the variables x & y, then
x is considered to be one of the numbers being more than y by the addition of 4, .ie.
x = 4 + y --- (1)
The sum of the 2 numbers is 60, i.e.
x + y = 60 --- (2)
To find the smaller number, we solve eqn (1) & (2) using the concept of substitution, i.e. substitute 4 + y for x in eqn (2), i.e.
4 + y + y = 60
4 + 2y = 60
2y = 60 - 4
2y = 56
y = 28 ...Ans.
Recall that x is more than y by 4, then 28 is the smaller number.
I think the answer is this
2x-4x+1=0
Combine like terms
-2x+1=0
Subtract 1 both sides
-2x=-1
Divide by -2 both sides
x=-1/2
Answer:
d =2.28 days
Step-by-step explanation:
Given:
V(d) = 350(0.6392)d + 2
Where,
V(d) = number of views
d = number of days
How many days will it take to
reach 100 views?
Find d when V = 100
V(d) = 350(0.6392)d + 2
100 = 350(0.6392)d + 2
100 = 223.72d + 2
100 - 2 = 223.72d
98 = 223.72d
d = 223.72/98
d = 2.2828571428571
Approximately
d =2.28 days
