Answer:

Step-by-step explanation:

It might help to use decimals

1 1/8 = 1.125

4 2/5 = 4.4

Add these together

1.125 + 4.4 = 5.525 That's the correct answer, but likely not in the form you wanted.

1 1/8 = 9/8

4 2/5 = 22/5

9/8 + 22/5

multiply through by the Lowest Common Denominator

9*5/40 + 22*8/40 =

45/40 + 176/40

221/40

5.525

5 21/40

You get the fraction by multiplying 40 * 0.525 which is 21

So you can express 0.525 as 21 / 40

he temperature at noon on a winter day was 2 °F. By 6 p.m., the temperature had dropped to −9 °F. Write a subtraction expression

nydimaria [60]

Based on the starting temperature and the new temperature, the relevant expression would be 2 - (-9)

To find the number of degrees the temperature has changed by, use the following equation:

= Starting temperature - Current temperature

Starting temperature = 2°F

Current temperature = -9°F

The equation becomes:

= 2 - (-9)

In conclusion, the expression would be 2 - (-9)

What’s the 5th term is 2,14,98

iragen [17]

$\bold{\huge{\orange{\underline{ Solution }}}}$

<h3>Correct Question :-</h3>

What is the 5th term of an AP 2 , 14 ....98 .

<h3>Given :- </h3>

We have AP, 

$\sf{ 2 , 14 ,.... 98 }$
AP is the arithmetic progression or a sequence of numbers in which succeeding number is differ from preceeding number by a common value.

<h3>Solution :-</h3>

We have an AP :- 2 , 14 .....98

Therefore,

$\sf{a1\: or \:1st\: term = 2 }$
$\sf{a2 \:or \:2nd\: term = 14 }$
$\sf{an \:or\: last\: term = 98}$

Here,

Common difference of an AP

$\sf{ a2 - a1 }$

$\sf{ = 14 - 2}$

$\sf{ = 12}$

Thus, The common difference is 12

Now, 

We know that,

$\sf{an = a1 + ( n - 1 )d}$

$\sf{a5 = 2 + ( 5 - 1 )12}$

$\sf{a5 = 2 + 4 × 12}$

$\sf{a5 = 2 + 48}$

$\sf{\red{a5 = 50}}$

Hence, The 5th term of given AP is 50
