Answer:

19+1=20

20+5=25

Step-by-step explanation:

since 19 is so close to 20, we can split the 6 into two groups, leaving us with 19 + 5 + 1. add 1 to 19 to make it 20, then add 5 to 20 to get 25.

1/3 (x+2)=-2/5 (x-9) and x=4
MAXImum [283]

Answer:

2 = 2 (Identity)

Step-by-step explanation:

1/3 (x+2)=-2/5 (x-9) and x=4

Follow distributive property

1/3x + 2/3 = -2/5x + 18/5

Replace x for 4

1/3(4) + 2/3 = -2/5(4) + 18/5

4/3 + 2/3 = -8/5 + 18/5

Add like terms

6/3 = 10/5

Simplify

2 = 2
