Answer:
A = 2, the number is 3221
Step-by-step explanation:
In order for the number to be divisible by 9, the sum of it's digit has to be divisible by 9.
In our case, 
where k is an integer. the easiest way happens when k=1
Higher values of k will likely most work (with k=2 you get A to be a non-integer, which can't work since it's the digit of a number, and with higher values of K you're not getting a number in base 10.
Answer:
(x+22) + x = 88
Step-by-step explanation:
if x is how much your friend collected, then how much you collected would be x + 22 because you collected 22 more then her. and if you add both of those together to get how much you collected together (the total) you get 88. so x (your friends sea shells) plus x+22 (your sea shells) is 88. tell me if you also need help solving the actual equation
you have x+22 + x = 88
you combine like terms, in this case the Xs
and you get 2x + 22 = 88
then you subtract 22 to both sides because you want to get x alone
and you get 2x = 88 - 22
which is 2x = 66
then you divide by 2 on both sides
and you get x = 66/2
and you get x = 33
$417.50 should be the correct answer you just multiply the $7.25 to 30 and then add the $200.
We have that
cos A=0.25
so
A=arc cos (0.25)-------> using a calculator----> A=75.5225°
Round to the nearest hundredth-----> A=75.52²
the answer is
the option <span>75.52°</span>
