Answer:
143
Step-by-step explanation:
180 - 37 = 143.
We know this because y + 37 = 180
so we can does 180-37 to get our answer.
You can make it easier by replacing x^n with another variable, factoring, then putting x^n back in the end.
Using exponent and algebra rules, rewrite x^2n - 2x^n + 1 as
(x^n)^2 - (2 x x^2) + 1
Then, let x^n = m.
m^2 - 2m + 1
Now factor that: (m - 1)^2
And now put x^n back: (x^n - 1)^2
X+2y=4
3x-2y=4
4x=8
x=2
2+2y=4
2y=2
y=1
y=1
x=2
Hope this helps :)
Answer:
20%
Step-by-step explanation:
to find out we make it a fraction:
14/70
then divide
14÷70=0.2
then times it by 100
= 20%
It would be 5 because its closer to five then it is 4
