If the circumference of a circle is 40 m, its area is 127.32395447352 m².
Answer:
-4u -5v
Step-by-step explanation:
Let the sum be ...
<3, -27> = a<3, 3> +b<-3, 3>
This resolves to two equations
3 = 3a -3b
-27 = 3a +3b
Adding these together, we get
-24 = 6a
a = -4
Substituting into the second equation gives ...
-27 = 3(-4) +3b
-15 = 3b
-5 = b
The desired linear combination is ...
<3, -27> = -4<3, 3> -5<-3, 3> = -4u -5v
So 22 is 44% of something
22=44% of x
'of' means multiply
22=44% times x
percent means parts out of 100
44%=44/100
22=44/100 times x
22=44x/100
multiply boht sides by 100
2200=44x
divide both sides by 44
50=x
the number is 50
