Answer:

C = 72

E = 500

Step-by-step explanation:

Is means equals  and of means multiply

a) 60% of C is 43.2

.60 *c = 43.2

Divide each side by .60

c = 43.2 / .6

C =72

b) 38% of E is 190

.38 *E = 190

Divide each side by .38

E = 190/.38

E =500

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

Grace [21]

Answer:

<em>(D). x = 2 , y = - 5</em>

Step-by-step explanation:

A = - 8 + 48 = 40

A_{x} = -76 + 156 = 80

A_{y} = 104 - 304 = - 200

<em>x =</em> \frac{A_{x} }{A} = <em>2</em>

<em>y =</em> \frac{A_{y} }{A} = <em>- 5</em>

<u><em>( 2, - 5 )</em></u>
