A sum of money was shared among Daniel Elliot and frank in the ratio 5 : 7 : 8 . If frank shares was $2,781 more than Daniel sha

aliya0001 [1]

Answer:

$18,540

Step-by-step explanation:

To find the original sum of money shared, setting up two different proportions using the ratios and the amount given will help. For the first proportion, we can set 'x' equal to the amount of money that Daniel received. Since Frank received $2,781 more than this amount, his amount is the expression 'x + 2781'. Using equivalent ratios, we can set up the following proportion:

$\frac{Frank}{Daniel}=\frac{8}{5}=\frac{(x+2781)}{x}$

Using cross-multiplication: 8x = 5(x + 2781)

Distribute: 8x = 5x + 13,905

Inverse operations: 3x = 13,905 or x = $4,635

Since 'x' represents the amount that Daniel received, than Frank received:

x + 2781 or 4,635 + 2,781 = $7,416

To find the remaining amount for Elliot, make another proportion:

$\frac{Daniel}{Elliot}=\frac{5}{7}=\frac{4635}{y}$

Cross-multiply and divide: 5x = 7(4635) or y = $6,489

Total amount = $6,489 + $4,635 + $7,416 = $18,540

WINSTONCH [101]

Answer:

Step-by-step explanation:

In order to find when the other car catches up to the other, you need to graph the distance and time for both cars. The linear function will represent their rate of speed, when the lines intersect, that is when car 2 catches up to car 1.

Hope this helps.

I need help ? which linear function is represented by the graph?

<h3>Answer: f(x) = (-1/2)x+1, choice B</h3>

=================================================

Explanation:

The diagonal line passes through 1 on the vertical y axis. So the y intercept is b = 1. This means the location of the y intercept is (0,1).

Start at (0,1) and move down 1 and to the right 2 to arrive at (2,0). This is another point on the diagonal line. The motion of "down 1 and right 2" is effectively the slope

slope = rise/run = -1/2

rise = -1, run = 2

The rise being negative means we have gone downhill as we move to the right.

With m = -1/2 as the slope and b = 1 as the y intercept, we go from y = mx+b to y = (-1/2)x+1

The last thing to do is replace y with f(x) to get f(x) = (-1/2)x+1 as the final answer.

Annette [7]

Answer:

$min(10,w)=\left \{ {{w} \quad\text{for } w$

Step-by-step explanation:

No value of w is given, so we can only tell you the meaning of <em>min(10, w)</em>:

When w < 10, min(10, w) is w.

When w ≥ 10, 10 is the smaller of the two values, so min(10, w) = 10.
