-6.3+d> 4 1/2

Step-by-step explanation:

She starts 6.3 miles west of her home. This is denoted by the (-). The store is 4.5 miles east of her home. East would be denoted by a (+). never be exactly 4.5 miles from her home. This would be denoted by a (>). Therefore the answer is: -6.3+d>4 1/2

The store is more than 4.5 miles east of her home meaning that it would never be exactly 4.5 miles from her home. This would be denoted by a (>). Therefore the answer is: -6.3+d>4 1/2

Answer:

[tex]given \: => \: s = \frac{2x + t}{r} \\ = > 2x + t = rs \\ = > 2x = rs - t \\ = > x = \frac{rs - t}{2} [/tex]

so..

option (1) is correct!!

hope helpful <3

Answer: Option 1 because of inverse operations

Step-by-step explanation:

Answer:

300 + r = 217

Step-by-step explanation:

300 -> 300

added to r -> +

is the same as -> =

217 -> 217

Put this in one equation and you get:

300 + r = 217

If you need to solve for r (need to isolate r to solve for r):

300 + r = 217

r = 217 / (-300)

r = -0.723333333

Answer:

B. 3y + 3y - 12

Step-by-step explanation:

A. 6y - 12y - 12 = -6y - 12   No

B. 3y + 3y - 12 = 6y - 12   Yes

C. 6y + 6y - 12 = 12y - 12    No

D. 12y - 6 - 6 = 12 - 12    No

Answer: B. 3y + 3y - 12

Answer:

B. 3y + 3y - 12

Answer:

A

Step-by-step explanation:

Answer:

U = 1

Answer = 6

Step-by-step explanation:

We can do really any number. But in this case, we are gonna do 1. So, it would look like (7 x 1) - 1. It would look like that because we know that 7u is equal to 7 times U or in this case, 7 times 1. So, we know 7 x 1 is 7. Now, we do 7 - 1 since U = 1, and we get our answer of 6.

Sorry guess I don’t know then

It could be wrong but I'm pretty sure I'm right.

For 1 pound of flour you cant make any batches or .083 of a batch.

For 34 pounds you can make 2.833 batches.

And finally, 14 pounds of flour gives you 1.166 batches.

To find these answers take your amount of flour and divide it by the 12 pounds of flour.

Example; 34 divided by 12 = 2.833

Example 2; 14 divided by 12 = 1.66

Answer:For 1 pound of flour you cant make any batches or .083 of a batch.

For 34 pounds you can make 2.833 batches.

And finally, 14 pounds of flour gives you 1.166 batches.

Answer:

earnings = $125 + ($50/vacuum)x

Step-by-step explanation:

This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:

The equation represents the man's total earnings.  The independent variable is x, the number of vacuums he sells.

Thus, earnings = $125 + ($50/vacuum)x.  As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).

Plot a black dot at (0, $125).  Now move 2 units to the right from this dot and from there up by $100 to (2, $225).  Plot this new point.  Then draw a line through the two points you've plotted.

Table:

 x   earnings

----  --------------

 0      $125

  1       $125 + $50 = $175

  2      $125 + $100 = $225

and so on.

the awnswr i believe is B, because a funcion has diffrent x's

Answer:

No, its not.

Step-by-step explanation:

Answer:

The means differ by 4 times the MAD.

Step-by-step explanation:

I may be missing something, but this is how I interpret it.

The mean number of deliveries for company A is 6, and the mean for company B is 14. Lastly, the mean absolute deviation (MAD) for both companies is 2.

[tex]14-6=8\\8\div2=4[/tex]

The means differ by 8, and that is 4 times the MAD, so the means differ by 4 times the MAD.

Answer:

-5np - r² + m + 45n - 6

Step-by-step explanation:

1) Eliminate redundant parentheses

m + 5n · (9 - p) - 6 - 1r²

2) Rearrange terms

m + 5n · ( - p + 9 ) - 6 - 1r²

3) Distribute

m - 5np + 45n - 6 - 1r²

4) Rearrange terms

-5np - r² + m + 45n - 6
