Q + d = 100 so q = 100 - d
0.25q + 0.10d = 19

substitute q = 100 - d into 0.25q + 0.10d = 19

0.25q + 0.10d = 19
0.25(100 - d) + 0.10d = 19
25 - 0.25d + 0.10d = 19
-0.15d = -6
        d = 40

q = 100 - 40 = 60

answer
Kitara has 60 quarters and 40 dimes

For each part below, use the figure to fill in the blank.
kobusy [5.1K]

Answer:

a) m<F = 70

b) AB = 6

Step-by-step explanation:

a)

Since this is an isoceles triangle, the base angles are equal so:

2x + 40 = 180

2x = 140

x = 70

b)

Since all of the angles are equal, this is an equilateral triangle. This also makes all of the sides equal and the same.
