A Sum of $14 is made of 92 coins consisting of dimes and quarters. How Many are there of each kind of coin
steposvetlana [31]
So first I would say, what if all of them were dimes, how far away would it be from $14?

So 92 coins * 10 cents = $9.20

So it's 4.80 dollars away from 14 dollars.

So if we were to switch one to a quarter, it would increase by 0.15 cents.

So we want to see how many increases we need to reach 4.80 dollars more.

4.80/0.15 = 32

So there are 32 quarters and 60 dimes.

FIND THE SLOPE OF THE LINE...<br><br> A) 1/2<br><br> B) 2<br><br> C) - 1/2<br><br> D) -2
Ainat [17]

Answer:

The slope would be C) -1/2

Step-by-step explanation:

To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)

m(slope) = (y2 - y1)/(x2 - x1)

m = (-3 - -4)/(0 - 2)

m = 1/-2

m = -1/2
