Answer:
The commutative property
Step-by-step explanation:
a math rule that says that the order in which we multiply numbers does not change the product.
1) The expressions are not equivalent. When you expand and multiply 2(x + 3) it becomes 2x + 6. This is not equal to 3x + 5
2) They are equivalent. Again, expand and multiply the second expression. 2(3n + 4) becomes 6n + 8. This makes both sides equal.
3) They are equivalent. In the parentheses, you are adding 3 y's and a 2. This gives you 3y + 2. Now add the additional 3y that follows the closed parentheses. You'll have 6y + 2. Now both sides are equivalent.
The answer is 2/9 because there is a total of 9 balls. And the chances are 2 so that's how we get 2/9
Hope I was help !!! :D
Answer:
- 3225
Step-by-step explanation:
d = 75
2d + ( - 45 d )
= 2 ( 75 ) - 45 ( 75 )
= 150 - 3375
= - 3225
Answer:
$83,320
Step-by-step explanation:
The formula to apply here is;

where;
A=Amount at the end
P=the amount to invest/principal
r=rate of interest as a decimal
n=number of compoundings in a year
t=time in years
Given that;
A=$400,000
P=?
r=8%=0.08
n=2
t=20
Substitute values in equation

P=$83,320 (to the nearest dollar)
