Is -6.7 equal to -6 7/10

2 answers:

6 0

Yes, -6.7 is equal to -6 and 7/10. We know that in -6.7, 7 is in the tenths place. So you would have -6 7/10. You can also divide 7 by 10. 7 divided by 10 equals .7. So -6.7 is equal to -6 7/10. I hope that I could help! It is a lot easier than it first sounds!

No, because -6.7 is negative 6 and 7 tenths and -67/10 is negative 67 tenths which is wrong, I think....

Hey there,

For the first one, your answer will be C. The height of the plant increases by 2 mm for every hour of sunlight it receives. For the second one, It is B.There is a strong negative relationship between x and y. And the last one is B. It is greater for Group B than Group A.

I hope I helped :)

A. .x=8 f(x)=1*1 (8) = ?

Ksenya-84 [330]

You are missing information.

f(x) needs to equal an equation that has an x in it.

f(x) = 1 * 1

x = 8

There is nowhere to fill in the 8.

Sorry. :(

Factor the expression 77x + 21

klemol [59]

Answer: 7(11x + 3) .
______________________________________________________
Explanation:
______________________________________________________
We are asked to: "Factor the expression: 77x + 21 ."
______________________________________________________
Upon examination of both: "77x" and "21" ; we can see that "7" is the greatest common factor (GCF) of BOTH. We can examine this visually, but let us write this out:
_______________________________________________________
21: 1, 3, 7, 21

77x ;
or simply: 77: 1, 7, 11, 77
_____________________________
So, to proceed:
_____________________________
Write down a: "7" ;
_______________________________
7 *( ????)
________________________________
Note the distributive property of multiplication:
______________________________________
a(b+c) = ab + ac ; AND:

a(b - c) = ab - ac ;
____________________________________________________
So , we write down a "7" ;
____________________________________________________
7*( ???
____________________________________________________
The first value is: "+77x" ; so, " 7 * ? = 77x ?" ;

We can examine this visually and realize that the value is "11x";

or we can divide, as follows: (77x/ 7 = 11x ).
___________________________________________
So we have already written down: 7* (??? )
________________________________________
We can down rewrite as: " 7 * (11x ......)
________________________________________
(since " 7 * 11x = 77x ") ;
_____________________________________
The next (and in our case, final !) value in our expression is:
__________________________________________________
" +21 " ;
__________________________________________________
We have written down: 7* (11x ......)
__________________________________________________
So now, we need to determine: "7 * ? = 21" ?
__________________________________________________
We can inspect visually and determine the value is: "3" ;
__________________________________________________
Or we can solve by division, as follows:
__________________________________________________
"7 * ? = 21 ?" ; 21 / 7 = ? ; 21 / 7 = 3 . The value is: "3" .
__________________________________________________
So , we have: " 7 * (11x .....) " ; now we can rewrite as:
____________________________________________________________
" 7*(11x + 3)" ; or, simply: " 7(11x +3)" ; The multiplication is implied).
_________________________________________________________
The answer is: 7(11x +3) .
_______________________________________
Does our answer make sense? Let us check!

The answer; " 7(11x +3) " is the factored expression of: "(77x + 21)" ;
__________________________________________________
So: " 7(11x +3) " should EQUAL "77x +21 " . Is this true??
___________________________________________________________

Remember the distributive property of multiplication:
________________________________________________________
a(b+c) = ab +ac ;
________________________________________________________
So; " 7(11x +3) " = (7*11x) + (7*3) ; which equals:
_______________________________________________
 77x + 21 . Yes!
________________________________________________________

PLEASE HELP ME WITH B AND C.

stepladder [879]

B)The numbers are being divided by 10 repeatedly.

The numbers are:

7000

700

.07

.007

(See it now?)

The number that is missing is 7

My conjecture is that 7 can’t be written in scientific notation.

Hope I helped!

Good Luck!
