Answer:
The number is 5
Step-by-step explanation:
6+3n = 5n-4
Subtract 3n from each side
6+3n-3n = 5n-3n-4
6 = 2n-4
Add 4 to each side
6+4 = 2n-4+4
10= 2n
Divide by 2
10/2 =2n/2
5=n
I got 157/990. Just don't ask me how. I just used my fancy TI-84 Calculator.
Answer:
L= 5+2s
Step-by-step explanation:
Let L = the larger # and S = the smaller #.
A large # is 5 more than twice a smaller #.....This gives Eq 1) L = 5 + 2S
Their sum is 80...This gives Eq 2) L + S = 80.
Substitute Eq 1) into Eq 2), you get
L + S = 80
5 + 2S + S = 80
L = 5 + 2S
Answer: A. X(–2, 2), Y(–10, 2), Z(–6, 10)
Step-by-step explanation: This looks a bit tough, but knowing that scale factors less than 1 are ½, ¼, etcetera, I come to this answer, also knowing that in the end, they must have an unproportional relationship.
I hope this is correct, and as always, I am joyous to assist anyone at anytime.
Hi there
Part A
The formula is
A=pe^rt
A future value?
P present value 1300
R interest rate 0.042
T time 5 years
A=1,300×e^(0.042×5)
A=1,603.78
Part B
A=pe^rt
A future value?
P present value 1300
R interest rate 0.042
T time 9/12
A=1,300×e^(0.042×(9÷12))
A=1,341.60
Good luck!
