Answer:
$43,450
Step-by-step explanation:
The last dollar in the ones place is 1.
Since this is less than 5, we have to round down.
Which gets us to 43,450.
Hope this helps! :)
Answer:
3,200,000
Step-by-step explanation:
3,153,007 rounds up to 3,200,00 because the number in the ten thousandths place is above 5.
Answer:
Lenght: 21 inches.
Width: 14 inches.
Step-by-step explanation:
1. You know that the width (W) of a rectangle is 7 inches less than the length (L), then:
![W=L-7](https://tex.z-dn.net/?f=W%3DL-7)
2. The perimeter is 70 inches.
3. The formula for calculate the perimeter of a rectangle is:
![P=2L+2W](https://tex.z-dn.net/?f=P%3D2L%2B2W)
3. Substitute
and the value of the perimeter into the equation to calculate the perimeter and solve for the length:
![70=2L+2(L-7)](https://tex.z-dn.net/?f=70%3D2L%2B2%28L-7%29)
![70=2L+2(L-7)\\84=4L\\L=21](https://tex.z-dn.net/?f=70%3D2L%2B2%28L-7%29%5C%5C84%3D4L%5C%5CL%3D21)
4. Then the width is:
![W=L-7=21-7=14](https://tex.z-dn.net/?f=W%3DL-7%3D21-7%3D14)
Answer:
Slope of the line 12=4x−6y is
.
Step-by-step explanation:
The slope line form is denoted by
y = mx + c
Where m is the slope and c is the y- intercept .
As given
The equation of the line is given by .
12=4x−6y
It is also written as
6y = 4x - 12
![y = \frac{4x}{6} -\frac{12}{6}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B4x%7D%7B6%7D%20-%5Cfrac%7B12%7D%7B6%7D)
Simplify the above
![y = \frac{2x}{3} -2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2x%7D%7B3%7D%20-2)
(Compare with y = mx + c )
Thus
![m = \frac{2}{3}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B2%7D%7B3%7D)
Therefore the slope of the line 12=4x−6y is
.
