Answer:

Step-by-step explanation: Additive inverse of −7=7

The multiplicative inverse of a number for any n is simply 1/n

The reciprocal of a number obtained is such that when it is multiplied with the original number the value equals to identity 1.

Multiplicative inverse of −7= − 1/7

​   Therefore, required sum is 7−  

7-  1/ 7=48

Answer:

Here we have the relation:

m = 140*h

Where m is the distance in miles, and h is time in hours.

And we want to complete a table like:

\left[\begin{array}{ccc}in, h&out, m\\&\\&\\&\\&\end{array}\right]

The way to complete this, is to evaluate the function:

m = 140*h

in different values of h, and then record both values of h and m in the table.

Let's use values of h that increase by 0.5, then:

if h = 0.5

m = 140*0.5 = 70

We have the pair: h = 0.5,  m = 70

if h = 1

m = 140*1 = 140

We have the pair: h = 1, m = 140

if h = 1.5

m = 140*1.5 = 210

Then we have the pair h = 1.5, m = 210

if h = 2

m = 140*2 = 280

We have the pair: h = 2, m = 280

Now we can complete the table, and it will be:

\left[\begin{array}{ccc}in, h&out, m\\0.5&70\\1&140\\1.5&210\\2&280\end{array}\right]

Karen was trying to factor 6x^2+10 She found that the greatest common factor of these terms was 2 and made an area model
Kay [80]
<h2>Explanation:</h2><h2></h2>

In this case we have the following expression:

6x^2+10

We know that Karen was trying to factor out this and she found that the greatest common factor of these terms was 2, in other words we can write this expression as:

2(3x^2+5)

An area model for this expression could be the area of a rectangle that has the following dimensions:

W=2 \\ \\ L=3x^2+5 \\ \\ \\ Where: \\ \\ W:width \\ \\ L:length

So the area model can be written as:

A=W\times L \\ \\ \boxed{A=2(3x^2+5)}

What is the solution to to the equation x − 2/5 = −1?
ZanzabumX [31]

Answer:

  • x = -0.6

Step-by-step Solution:

<u>Isolate the variable x to get the answer.</u>

  • x − 2/5 = −1
  • => x = -1 + 2/5
  • => x = -1 + 0.4
  • => x = -0.6

Hence, the value of x is -0.6.
