Michael has 1.85 in dimes and nickels.He has a total of 25 coins.how many of each does he have

creativ13 [48]

D+n=25 subtract d from both sides *(if your wondering what d and n are it stands for Dimes and Nickels)* n=25-d
0.10d+0.05= 1.85
0.10d+0.05(25-d)= 1.85
0.10d+1.25-0.05d= 1.85
0.05d = 0.60
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My answer: He has 12 dimes (d=12) and 25-12=13 so 13 nickels.. Hope this helps! :)

<span>2x-4y=32
2x-8y=48
--------------subtract
4y = - 16
y = -4

</span>2x-4y=32
2x- 4(-4)=32
2x + 16 = 32

Answer:

Option D

Step-by-step explanation:

A). From the graph attached,

Arrow AB represents the RISE and arrow BC represents the RUN.

B). RUN from point A to B (Horizontal distance) = 2 units

Rise from point A to B (Vertical distance) = -4 [Since, downwards arrow represents negative notation]

Slope of the line segment AB = $\frac{\text{Rise}}{\text{Run}}$

= $\frac{-4}{2}$

= -2

Therefore, slope of the line = slope of the line segment AB = -2

Option D will be the correct option.
