Answer:
- 30 + 5v
Step-by-step explanation:
- 3(10 - 5v) - 10v ( multiply each term in the parenthesis by - 3 )
= - 30 + 15v - 10v ← collect like terms
= - 30 + 5v
Answer:
1. with the aid of a saw
2.No
Step-by-step explanation:
A. The 9‘ x 9‘ can be divided into two with the aid of a saw .
we have to take into account the area of the shape wic 9'x9'. and then saw the piece at the middle.
b.there are two sides to the second answer
1. the area of the smaller pieces will be smaller than the area of the larger piece
2. when the smaller pieces are placed side by side aain , tere area combined together will be the same as the original piece
Hi. I begin by finding the positive factors of 14. They are: 1 x 14 and 2 x 7. None of those can be added to yield a negative number, so let's now instead consider their negatives: -1 x -14 and -2 x -7. Does either of these pairs, when added, yield -9? Yes: -2 and -7.
To be clear: -2 x -7 = 14; and -2 + -7 = -9.
So the answer is -2 and -7.
Answer: The number is: "2" .
_______________________________________________________
The expression is: 2 − (½)x = (½)<span>x ;
</span>→<span> in which "x" is the "unknown number".
</span>_______________________________________________________
Explanation:
______________________________________________________
Given:
_________________________________________________________
"Two decreased by a half of a number is one-half<span> of the number" ;
Let "x" represent the "unknown number" for which we wish to solve;
Write the expression as:
_________________________________________________
" </span>2 − (½)x = (½)x " .
_________________________________________________
Note: Add "(½)x" to EACH SIDE of the equation:
_________________________________________________
2 − (½)x + (½)x = (½)x + (<span>½)</span>x ;
to get:
_________________________________________________
→ 2 = 1x ;
↔ 1x = 2 ;
↔ x = 2 .
