Answer:

  24

Step-by-step explanation:

Let d represent the number of dimes. Then (57-d) is the number of quarters, and the total value (in cents) is ...

  10d +25(57 -d) = 1065

  -15d +1425 = 1065 . . . . . . simplify

  -15d = -360 . . . . . . . . . . subtract 1425

  d = -360/-15 = 24 . . . divide by the coefficient of d

There are 24 dimes in the jar.

What is the solution to the inequality shown? -2(x + 3) < 6 - x x > -12 x < -12 x > 12 x < 12
Sonja [21]

Answer:

x < -12

Step-by-step explanation:

Given the inequality

-2(x + 3) < 6 - x

Expand

-2x - 6 < 6 - x

Collect the like terms;

-2x + x < 6 + 6

-x < 12

Multiply through by -1

-1(-x) < -1(12)

x < -12
