Carl collects coins compulsively, but he only likes quarters ($0.25) and dimes ($0.10). Carl currently has 125 coins for a total

of $26.00. How many of each coin does Carl have?

Answer:

Carl has 35 dimes and 90 quarters

Step-by-step explanation:

Let the number of quarters be q and the number of dimes be d

Total number of coins is 125;

Hence;

q + d = 125 •••••••••(i)

The total value of quarters present = q * 0.25 = 0.25q

The total value of dimes present = d * 0.1 = 0.1d

Adding both gives the total

0.25q + 0.1d =26 ••••••••(ii)

So we need to solve both equations simultaneously;

From i,

q = 125 - d

Substitute this into ii

0.25(125-d) + 0.1d = 26

31.25 -0.25d + 0.1d = 26

31.25 -26 = 0.25d -0.1d

5.25 = 0.15d

d = 5.25/0.15

d = 35

Recall; q = 125 - d = 125 -35 = 90

which equation can replace 3x 5y = 59 in the original system and still produce the same solution? 2x – y = –4 10x – 5y = –20 7x
natka813 [3]
From my research, the original system of equations contain the following equations:

<span>2x − y = −4 
3x + 5y = 59

where obtained solution is x = 3

Among the choices, it is easier to substitute </span><span>3x + 5y = 59 with one of the choices to see if they yield the same solution set. From trial-and-error, the equation that can replace the original equation is " 13x = 39 ". Among the choices, it is the 4th choice.</span>

Write and solve an equation of ratios, as follows:

32 fl oz              60 min
-----------     =     ------------
      x                  135 min

Then 60x = (32)(135) = 4320, and x = 72 oz.

damron should drink 72 fl. oz. of water if he rides 135 min.

A triangle has 2 angles that measure 60°. What kind of triangle is it?
QveST [7]
The correct answer to your question is an equilateral triangle. this is because all triangles must equal 180 degrees,, and if you already have two 60 degree angles then youre only 60 degrees away from 180. this means that every angle of your triangle is going to equal 60 degrees, and when all angles of a triangle are the same, then it becomes an equilateral triangle. this could also be considered an acute triangle since all angles are less than 90 degrees.
