The answer is 13 because a quarter is 25 cents so subtract 90 by 25 to get 65. Then you would divide 65 by 5 cents for the nickels and get 13.
10.2 inches
Step-by-step explanation:
The initial diameter of the base ball is 20 inches
Reducing this diameter by 20% means; (100-20)/100 * 20
80/100 *20 =16 inches
Reducing this diameter by 20% for the second time gives
80/100* 16 = 12.8 inches
Reducing this for the third time gives;
80/100 * 12.8 =10.24 inches

7 cause the amount you paid and it subtracts the amount of money you have
Answer:
1. -8x² - 16x - 6 a = -8, b = -16, c = -6
1. 4x² - 1 a = 4, b = 0, c = -1
Step-by-step explanation:
use the 'foil' method:
(4x + 2)(-2x - 3)
F: -8x² O: -12x I: -4x L: -6
-8x² - 16x - 6
(2x + 1)(2x - 1)
F: 4x² O: -2x I: 2x L: -1
4x² - 1
Answer:
x = - 12 6/7
Step-by-step explanation:
x - 12x/5= 18
Get a common denominator on the left
5/5 x -12/5x = 18
Subtract
-7/5 x = 18
Multiply each side by -5/7 to isolate x
-5/7 *-7/5 x = -5/7 *18
x = -5*18/7
x = -90/7
Changing this to a mixed number
7 goes into 90 1 2 times with 6 left over
x = - 12 6/7
