Answer:15
Step-by-step explanation: 7 and a half times 2 is 15
Answer:
76
Step-by-step explanation:because its the answer
Let us assume the common ratio to be = x
Then
7x + 8x = 45
15x = 45
x = 45/15
= 3
Then the two numbers are
7x :8x
7 * 3:8 * 3
21: 24
Then the two numbers are 21 and 24.
I hope the procedure in which
the problem is done is clear to you. This is a simple but effective way of
solving such problems. In future this method will make you confident about
solving these kind of problems.
F(-4x)=4x+4x
set up the composite function and simplify!
