No, 22 should stay on its own side but x needs to be alone. so start on the 7+3x side and get 22 alone.                  
22=7+3x  should start with subtracting seven instead of 22 then dividing by 3 and you will find the answer

Is there a commutative property of subtraction that states a-b=b-a? investigate and make a conclusion that you justify.
Rom4ik [11]

No is your answer

Assuming that b ≠ a, the answers will not be the same.

For example, (remembering that b ≠ a) let us assume that b = 10, a = 5

10 - 5 = 5

5 - 10 = -5

5 ≠ -5

So the commutative property of subtraction does not work unless in certain cases, in which a = b.

hope this helps

A former sells 9.4 kilograms of pears and apples at the farmers market. 4/5 of this weight is pears and the rest is apples. How
SCORPION-xisa [38]

Answer:

1.88

Step-by-step explanation:

A farmer sells 9.4 kilograms of pears and apples

4/5 of the total weight is pears while the rest is apple

Let x represent the number of apples

9.4= 4/5 ×9.4 + x

9.4 = 0.8×9.4+x

9.4 = 7.52+ x

9.4-7.52= x

1.88= x

x= 1.88

Which point lies on the line defined by 2x – y = 7?
Eduardwww [97]
So lets just assume that y = 1 since 2x is most likely an even number.
Then we can say that 2x = 8
8 divided by 2 is 4
so a point on this line could be (4,1)
Hope this helped

(240 x 240) divide by 100
