Answer:

c = - 20

Step-by-step explanation:

Given

- 21 = $\frac{1}{2}$ c - 11 ( add 11 to both sides )

- 10 = $\frac{1}{2}$ c ( multiply both sides by 2 to clear the fraction )

- 20 = c , that is

c = - 20

riadik2000 [5.3K]

Answer:

x = nickels

y= dimes

x + y = 34

.05x + .10y= $1.90

-.10x - .10y = -3.40

-.05x + .10y = 1.90

-.05x = -1.50

x = 30 nickels

30 + y = 34

y = 4 dimes
