So, this is kind of a hard concept to explain without any pictures, but I'll try anyways.
Think of a plane as like a sheet of paper, and a line as a metal rod.
If I want to intersect the plane, it means that my line (rod) has to touch the plane (paper).
If I poke the rod through the paper, it only intersects it in one place, and I cannot fold or warp the paper to change that.
The only other way I can make these two touch is if I lay the rod on top of the paper. However, when I do this the paper is touching every single point along the rod...
I hope this kinda helps explain why you can never intersect in exactly two points.

Answer:
$262.50
Step-by-step explanation:
7 Months is approximately 30 weeks.
25 x 30 = $750
10% = $75
5% = $37.50
60% = (75x6) = $450
$450 + $37.50 = $487.50
$750 - $487.50 = $262.50
Answer:
3 2/3
Step-by-step explanation:
Answer:the pair of simultanous equations that model Andy's and Ron's ages are
3A-2R=6----Equation 1
R-A =2----Equation 2
Andy is 10 Years and Ron is 12 years
Step-by-step explanation:
Andy's age is represented as A
and Ron';s age is represented as R
Now if Andy multiplies his own age by 3. He then subtracts twice Ron's age. The answer is 6 can be expressed mathematically as
3A-2R=6
And if Ron subtracts his age from Andy's age. The answer is −2 can be expressed as
R-A =2
Therefore the pair of simultaneous equations that model Andy's and Ron's ages are
3A-2R=6----Equation 1
R-A =2----Equation 2
Solving becomes
3A-2R=6----Equation 1
R-A =2----Equation 2
Make R subject formulae in equation 2
R =2+A
Putting R =2+A in equation 1
3A-2(2+A)=6
3A -4-2A =6
A-4=6
A=6+4=10
From eqn 2,
R-A =2
R-10 =2
R=10+2=12
Andy is 10 Years and Ron is 12 years
