The sum of two irrational numbers<span> is SOMETIMES </span>irrational<span>. The </span>sum of two irrational numbers<span>, in some cases, will be </span>irrational. However, if the irrational<span> parts of the </span>numbers<span> have a zero </span>sum<span>(cancel each other out), the </span>sum<span> will be </span>rational<span>. But Remember the sum of two irrational number is sometimes irrational. Hope this helped :)</span>
Answer:
ok then
Step-by-step explanation:
By "inspection" you can write the equation as
.. x + y = 10
Then
.. y = -x +10 . . . . . . . . the desired form
Equations:
m = k + 5
k = s + 2
m + k + s = 30
-----------------------
Substitute for "m" and for "s"::
k+5 + k + k-2 = 30
3k +3 = 30
3k = 27
Kirsty has 9 marbles
---
Mina has 9+5 = 14 marbles
Seb has 9-2 = 7 marbles
A =(b1+b2)h/2
actual b1 =10cm*10m/1cm =100m
actual b2 = 6cm*10m/1 cm = 60m
height = 5 cm*10m/1cm = 50m
A=(100+60)*50/2 = 160*50/2 =80*50= 4,000 m²
Answer : <span>C.=4,000 m²</span>
