Question 10

Mathematics
1 answer:
Anettt [7]3 years ago
6 0

Answer:

THere are 33 quarters and 151 nickles

Step-by-step explanation:

Let q be the number of quarters in the bag

Let n be the number of nickles in the bag

Because there are a total of 184 we have a equation:

q + n = 184

Because the total value of the coins is $15.80 so we have another equation

0.25q + 0.05n = $15.80

<=> q + 0.2n = 63.2

We have q + n - (q + 0.2n) = 184 - 63.2

<=> 0.8n = 120.8

<=> n = 151

<=> q = 184 - 151 = 33

What is the point and slope of the line represented by the equation below y-4=-5(x+3)
Vedmedyk [2.9K]
The slope is -5.
The point is (-3, 4)
The formula for point slope form is
y-y1=m(x-x1) where y1 and x1 are the coordiantes of the point and m is the slope.
This shows that the y coordinate is positive and the x coordinate is negative.
May seem counterintuitive. So just flip signs that you see in formula to make the actual point if you are confused.

-5 (p+2)=2 (2p-15)+p
Bess [88]
-5 (p+2)=2 (2p-15)+p 

-5p-10=4p-30+p&#10;&#10;  \text{Expand} 

-5p-10=5p-30&#10; 

-10=5p-30+5p&#10;  \text{Add 5p to both sides} 

-10=10p-30&#10;&#10; 

-10+30=10p&#10;  \text{Add 30 to both sides} 

20=10p&#10; 

\dfrac{20}{10}=p  \text{Divide both sides by 10} 

p=2  \text{Solution}

Need help with question 4
Katarina [22]

9514 1404 393

Answer:

  16/7

Step-by-step explanation:

If the segments are congruent, their lengths are equal:

  (1/2)x -3 = 5 -3x

  (3 1/2)x = 8

  x = 8/(3.5) = 16/7

The value of x is 16/7.

_____

<em>Comment on the question</em>

This value of x makes the lengths of the segments be -13/7 units. Usually, negative lengths are considered impossible for line segments.
