Asquirrel family collected 172 nuts to store for the winter. they spread the nuts out evenly among their 6 favorite spots. the squirrels ate the last few nuts that didn't divide evenly . sadly, a crow stole half the nuts from one of the spots. how many nuts did the crow steal?

14

Step-by-step explanation:

172/6 = 28 with four as a remainder. if each group had 28 nuts and if the crow stole half of one of them, 28/2 is the answer which is 14.

steps:

1. 172/6= 28.66 repeating.

2. 26.66 is also 28 and 4 remainder

3. 28/2 = 14

14 is the answer

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
