Common differnce
an=a1+d(n-1)
d=common difference
a1=first term
so

given

common difernce is -3 and first term is 7
an=7-3(n-1)
14th term
a14=7-3(14-1)
a14=7-3(13)
a14=7-39
a14=-32

the 14th term is -32
A is answer

I got A, -32, but it has been awhile since I have learned this in my math class. You might want to wait for someone else to verify this answer.

How many two-digit numbers are there in which the tens digit is greater than<br> the ones digit?
Dovator [93]

there are 46 2-digit numbers in which the tens digit is greater than the ones digit.

<h3>How many 2-digit numbers are there in which the tens digit is larger than the ones digit?</h3>

A 2-digit number is written as:

a*10 + b

Where a and b are single-digit numbers.

Tens digit and ones digit refers to place values:

a is the tens digit, and b is the ones digit. The numbers with a larger tens digit than the ones digit are:

98, 97, 96, 95, 94, 93, 92, 91, 90, 87, 86, 85, 84, 83, 82, 81, 80, 76, 75, 75, 74, 73, 72, 71, 70, 65, 64, 63, 62, 61, 60, 54, 53, 52, 51, 50, 43, 42, 41, 40, 32, 31, 30, 21, 20, 10.

We can see that there are 46 numbers in that list, so we conclude that there are 46 2-digit numbers in which the tens digit is greater than the ones digit.

The equation c = start fraction: numerator: 5 denominator: 9: end fraction (f – 32) is used to convert temperature from degrees
krek1111 [17]
It will increase by 5/9 of a degree.

If you convert the given equation into slope intercept form, you will have:

c = (5/9)f + 160/9

In this form, it is easier to see the slope. The line would be increase by a rate of 5/9.
