8 + (9 + 2

3) − 9 + 8 × 6 ÷ 3 = ​

47

Step-by-step explanation:

follow Pemdas order of operations.

8 + (9 + 23) − 9 + 8 × 6 ÷ 3 = ​

8 + (32) - 9 + 8 x 6 ÷ 3

8 + (32) - 9 + 16

add and subtract the rest and u get 47

tigers

step-by-step explanation:

cougars 12/10 (12-10 = 2)

bobcats 20/10 (20-10 =10)

bulldogs 8/5 (8-5 =3)

tigers 3/5 (3-5 =-2)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
