Answer: D 1881
Step-by-step explanation: 6889 and 1961 don't read the same forwards and backward. 1991 upside down is 1661. So, only 1881 works
Answer: AB = 21
Step-by-step explanation:
Find the value of x by setting them equal to each other
x + 5 = 2x - 11
solve like a normal two step equation
x = 16
Answer:
Step-by-step explanation:
By the vertical angle theorem which states that angle opposite to each other is equal, we know the whole angle opposite to the angle that is 90 degrees (since it has a little square on the angle) is also ninety degrees.
However, that angle is split into two more angles one that is 22 degrees and the other being x degrees. Yet both of them added up equal to 90 degrees.
Thus we get the equation:
x + 22 = 90
x = 68 degrees
Hope that helps!
So, there are multiple forms of this. First there's improper fraction form which would be
There's also decimal form
(the .6 is repeating).
Hope this helps!
Answer:
5=25, 6=36 n=n×n
Step-by-step explanation:
If you look at the numbers side by side, the number on the right is just the number on the left multiplied by itself. You cannot find the exact answer for n but you can create an equation for it.
