Answer:
8 and 2
Step-by-step explanation:
Let x = the smaller number.
Let y = the larger number.
Let the numbers be x and y
x+y = 10 ..............(1)
y= 4x ........(2)
Put value of y into equation 1
x + y = 10
4x + x = 10
5x = 10
Divide both sides by 5
x = 10/5 = 2
Put value of y into equation 2
y= 4x
y= 4(2)
y = 8
Therefore the numbers are 8 and 2

438 since 584 divided by .25 is 146. Then you subtract 584 and 146 to $438
75 degrees because 42+63=105
180-105=x
Answer:
the given equation is y=4/7x
reciprocating both sides you get y/x =7/4
now x and y are directly porportional to each other so
x=ky where k is the constant
or x/y=k ......................(2)
equating 1 and 2
k=7/4

Answer:
Step-by-step explanation:
Given that:
Principal = $650
Interest rate, r = 2.3% = 0.023 compounded daily
Time, t it takes for final amount, A to reach $880
Using the relation :
A = P(1 + r/n)^nt
n = number of times compounded per period
Hence, n = 365
880 = 650(1 + 0.023/365)^365t
880/650 = 1.0000630^365t
1.3538461 = 1.0000630^365t
Take the log
0.1315692 = 0.0000273596 * 365t
0.1315692 = 0.0099862t
t = 0.1315692 / 0.0099862
t = 13.175101
t = 13.18 years a
