8 0

Answer:

See below.

Step-by-step explanation:

Let d = number of dimes. Let q = number of quarters.

d + q = 35

A dime is worth 10 cents, or $0.1; d dimes are worth 0.1d.

A quarter is worth 25 cents, or $0.25; q quarters are worth 0.25q.

0.1d + 0.25q = 4.9

The system of equation is

d + q = 35

0.1d + 0.25q = 4.9

How do I factor: x to the third minus 3x squared plus 4x minus 2
Nataliya [291]

Answer:

(x² − 2x + 2) (x − 1)

Step-by-step explanation:

Use grouping.

x³ − 3x² + 4x − 2

x³ − 3x² + 2x + 2x − 2

x (x² − 3x + 2) + 2 (x − 1)

x (x − 2) (x − 1) + 2 (x − 1)

(x (x − 2) + 2) (x − 1)

(x² − 2x + 2) (x − 1)

-----.135as a fraction
Mrac [35]
This has to do with place value.
0.135.....the last digit (5) is in the thousandths place....so put it over 1000.
135/1000 reduces to 27/200
