Lets Sean's age be x
Helen's age by y
x/y=3/5
x=3/5y
Second equation
2(x-2)=y-2
on solving u get Helen as 10 and Sean as 6
I think the answer would be 7/50
The proportional graph that corresponds to M = 3n is: Graph C.
<h3>What is a Proportional Graph?</h3>
The constant of proportionality, k, of a proportional graph is given as, y/x. The graph is expressed by the equation, y = kx.
The equation given, M = 3n, represents a proportional relationship where k = 3.
Using a point on graph C, (400, 1,200):
k = 1,200/400
k = 3
Therefore, the graph that corresponds to the situation is: C.

Answer:
a) $26.4
b) $324
Step-by-step explanation:
Hire purchase is the purchase of an item which can be paid instalmentally.
The bicycle costs $300 for an instant purchase.
For a hire purchase, a $60 deposit must be made and the rest paid instalmentally over 10 months. An interest of 10% is included in the outstanding balance
The outstanding balance after paying deposit= $300 - $60 = $240
Hence, 10% of 240 = 10/100 × 240 = 24
An interest of $24 is added.
Therefore, a total of $240 + $24 = $264 will be paid for the next 10 months.
a) Hence, the amount to be paid in instalment each month is $264/10 = $26.4
b) the total cost of buying the bicycle by hire purchase= deposit amount + instalment price
= $60 + $264
= $324
Hence, a total of $324 will be paid for the bicycle by hire purchase.
N.B: $300 is the sale price + $24 interest
Answer:
A
Step-by-step explanation:
f(g(3)= f(g(x=3)) = f(
) = f(4/2) = f(2) = f(x=2) = 3*2-7 = 6-7 = -1
