Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion
7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)
7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer
X=0 because when you have something to the power of zero your answer is 1.
x=0 since 1 to the power of zero equals 1.
hope im not too late
5% of 210000=
(210000/100)5= $10500 anually
so 4 years will be $42000
he'll pay 42000 + 210000
$252000
answer is B
The first solution contributes 0.78*1 = 0.78 L of acid.
The second contributes 0.64*6 = 3.84 L of acid.
There will be 7 L total of the new solution, and 3.84 + 0.78 = 4.62 total L of acid in it. So the new solution has a concentration of 4.62/7 = 0.66, or about 66%.
Hello!
You can write down what the possible numbers their are
The numbers greater than 2 are 3, 4, 5, and 6
The numbers that are odd are 1, 3, and 5
List all the numbers out in a row
3, 4, 5, 6, 1, 3, 5,
Eliminate one of the numbers that repeat
3, 4, 5, 6, 1
You put the amount of answers of the total amount of outcomes
The answer is 5/6
Hope this helps!
