Answer:
A
Step-by-step explanation:
In (4,5) the difference between 5 and 4 is 1, the same applies for (8,9), therefore y=x+1 is a linear function of y=x+1
So using this function: (1,2),(2,3),(3,4)(4,5) etc
Answer:
x=7.608696
Step-by-step explanation:
Simplify both sides of the equation.
262.5=10.5x+24x
262.5=(10.5x+24x)(Combine Like Terms)
262.5=34.5x
262.5=34.5x
Step 2: Flip the equation.
34.5x=262.5
Step 3: Divide both sides by 34.5.
34.5x
34.5
=
262.5
34.5
x=7.608696
Answer:kilometers
Step-by-step explanation:
Answer:
18 years ( approx )
Step-by-step explanation:
Since, if an amount is compounded daily,
Then, the final amount after t years is,
A= P(1 + r/365) 365t
Where, P is the principal amount
r is the annual rate ( in decimals ),
t is the number of years,
Given,
A = $ 800,
r = 3.9% = 0.039,
P = $ 400,
By substituting the values,
800= 400 (1 + 0.039/365)365t
t = 17.774 = 18
Hence, his balance will be $800 after approximately 18 years.
Answer:
Lee has 19 nickels and 8 dimes
Step-by-step explanation:
hello, I think I can help you with this
Step 1
Let
value of a nickel=$0.05
value of a dime=$0.10
number of nickels=N
number of nickels=D
According to the question data Lee has $1.75 in dimes and nickels.
0.05N+0.1D=1.75,equation(1)
also, the number of nickels is 11 more than the number of dimes.mathematical speaking
N=11+D,equation(2)
Step 2
replace N from equation (2) into equation (1)
0.05N+0.1D=1.75
0.05(11+D)+0.1D=1.75
Now, solve for D
0.55+0.05D+0.1D=1.75
0.15D=1.75-0.55
D=1.2/0.15
D=8
Step 3
replace the value of D into equation(2) to obtain N
N=11+8
N=11+8
N=19
Hence, Lee has 19 nickels and 8 dimes
Have a great day.
