3 0

Answer:

10 nickels 3 quarters

Step-by-step explanation:

# of nickels =x

# of quarters =13-x

value of nickels =5x

value of quarters = 25(13-x)

Total amount 125 cents

5x+25(13-x)=125

5x-325-25x=125

-20x=-200

x=-200/-20

x=10     number of nickels

quarters=    13-10=3

Find the value of x and y
Aleks04 [339]

Answer:

x=30

y=17

Step-by-step explanation:

We know that 6x+9 = 129  since they are vertical angles

6x+9 = 129

Subtract 9 from each side

6x+9 -9 =129-9

6x = 120

Divide by 6

6x/6 =120/6

x = 20

3y+129 =180  since they make a straight line and straight line are equal to 180 degrees

3y+129 =180

Subtract 129 from each side

3y+129-129=180-129

3y = 51

Divide by 3

3y/3 = 51/3

y = 17

Solve 9x^2 + 12x – 24 = 0 using the quadratic formula.
Nataliya [291]
Quadratic formula = (-b +- sqrt(b^2 - (4ac))) / 2a

\frac{ -12 +  \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}

and

\frac{ -12 - \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}

then simplify and solve
