Answer:
x=-2
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
I believe the answer to this is 4165750000000.
Answer:
4
Step-by-step explanation:
A simple matter of using Pythagoras. The hypotenuse is the ladder, and one of the legs is the wall, and we have to figure out the value of the other leg.
The Pythagorean formuda is (hypotenuse = a): a² + b² = c² (b and c are the other sides)
applying the values: a = 5 and b or c is 3 (I'll put b = 3)
5² = 3² + c²
25 = 9 + c²
25 - 9 = c²
16 = c²
√16 = c
4 = c
c = 4
A = number of $1 bill
B = number of $5 bill
A + B = 1919
A*$1 + B*$5 = 5959
so
A + B = 1919
A + 5B = 5959
Substract both equation
A + 5B - (A + B) = 5959 - 1919
4B = 4040
B = 1010
And
A = 1919 - B = 1919 - 1010 = 909
A = 909
Check the result :
A*$1 + B*$5 = 909 + 1010*5 = 909 + 5050 = 5959
Answer:
7 years
Step-by-step explanation:
Because there is no graph, I will just tell you how many years it should take, and you can probably figure it out from there. To start, let's [get out a calculator] find out what 2% of 250 is. This is 5, so we can add 5. Notice that adding 5 to the number does not change 2% of it by much, only by 5/50 or 0.1. So, we can keep adding until we get above 282, which should take 285 minus 250 over 5 times, or 7. So, the answer is 7 years. You can [get out a calculator] and find out that it is indeed 7 years.
