Wednesday
O= 6 phone calls
How many phone calls did the school receive in all?
8 phone calls
B
48 phone calls
54 phone calls
D
18 phone calls

B

Step-by-step explanation:

(Each counter = 6 phone calls)

Monday = 000

Tuesday = 000

Wednesday = 00

Total = 00000000

8 x 6 = 48

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
