Hi I really need help with this question. SHOW YOUR WORK IF YOU ARE WILLING TO HELP ME TY! <3 (4.5+7.6)-8/2.5

Answers

Answer 1

Answer:

Answer:

8.9

Step-by-step explanation:

Parenthesis are always first so,

4.5+7.6=12.1

so the problem would look like this now:

12.1-8/2.5

so convert 8/2.5 to 8÷1/5÷2 so this will become 16/5

16.5 concerted to decimal=3.2

so 12.1-3.2=8.9

What is the reciprocal of 3 1/4?

Answers

By using the concept of reciprocal of fraction, the result obtained is -

Reciprocal of $3(1)/(4)$ is $(4)/(13)$

What is reciprocal of a fraction?

At first, it is important to know about fraction.

Suppose there is a collection of objects and a part of the collection has to be taken. The part which is taken is called fraction. In other words, part of a whole is called fraction.

The upper part of the fraction is called numerator and the lower part of the fraction is called denominator.

For example: $(4)/(7)$ is a fraction. Here, 4 is the numerator of the fraction and 7 is the denominator of the fraction.

Let p be a fraction. Reciprocal of p is a fraction in which if the fraction is multiplied by p, the result obtained is 1 (multiplicative identity)

Here,

$3(1)/(4) = (13)/(4)$

Let the reciprocal of $(13)/(4)$ be x

$(13)/(4) * x = 1\n\n13x = 1* 4\n\n13x = 4\n\nx = (4)/(13)$

Reciprocal of $3(1)/(4)$ is $(4)/(13)$

if u calculate 3 1/4 u would get 13/4

This means to get the reciprocal fraction of 13/4 just turn it upside down like this

13/4= 4/13 so ur answer is 4/13

-r + 6 +8r -14
Simplify the expressions by combining like terms?

Answers

-r + 6 + 8r - 14

Add up all the 'r's: -r + 8r = 7r

Add up all of the
just-plain-numbers: + 6 - 14 = - 8

The whole messy complicated expression is the same as 7r - 8 .
