252 will most likely support it because if you simplify 30 over 50 then u get 3 over 5, then 5 divided by 420 is 84. If you multiply 84 by 3 then you get 252
Answer:
7) 15
Step-by-step explanation:
7) 20% = 3 problems
20 x 5 = 100
3 x 5 = 15
I think it is the first one! When you plug in -7 as ^an, it follows the sequence #1.
Example: a1 = 7 an = 2 + an
you would do this:
first term = 7, second = 7+2 = 9, third = 9+2 = 11, ..........

<span>George And Carmen Went On A Bicycle Trip. They Took A Bus To Their Starting Point Then Biked The Rest.
They Traveled 275 Kilometers In Total,
And They Biked 55 Kilometers More Than They Were Bussed.
Let X=Kilometers Traveled By Bike
Let Y=Kilometers Traveled By Bus.
Find How Many Kilometers They Traveled By Bike.
--------
X + Y = 275 km
X = Y + 55
-------------
Substitute or X and solve for "Y":
Y+55 + Y = 275
2Y = 220
Y = 110 km (distance traveled by Bus)
-------
Solve for "X":
X = Y + 55
X = 110+55 = 165 km (distance traveled by Bike)</span>
Answer:
y^2-5. In the quadratic formula there is always an exponent.
