Answer:
hour= 1.25
MINUTES ANSWER= 75 minutes
Step-by-step explanation:
hope that helps>3
Here,
Third term (a) = 5
Seventh term (b) = 9
17th number = ?
Now,
T3 = a + 2d
5 = a + 2d
d = (5 - a)/2 ------ 1.
T7 = a + 6d
9 = a + 6d
d = (9 - a)/6 ------- 2.
Combining eq (1) and (2)
or, (5 - a)/2 = (9 - a)/6
or, 6 (5 - a) = 2 (9 -a)
or, 30 - 6a = 18 - 2a
or, 12 = 4a
◆ a = 3
putting the value of a in eq (1)
or, d = (5 - 3)/2
or, d = 2/2
◆ d = 1
Then,
T17 = a + 16d
= 3 + 16
= 19
◆ T17 = 19
I hope you understand...
This is Right answer...

Answer:
(x + 5) - 9
Step-by-step explanation:
An expression is a mathematical phrase that contains a variable and a constant, but not an equal sign. Using key words from the given verbal expression, we can make an algebraic expresion:
'nine less than' = subtract 9 or - 9
'the sum of x and 5' = addition of 'x' and '5' or x + 5
put them together: (x + 5) - 9
