Lines that intersect are intersecting or crossing lines.
Perpendicular lines are lines that cross at a 90 degree angle.
Skew lines are lines that are non-coplanar and don’t intersect.
The balloons of each color that Marty inflated are:
- Marty
- inflate
- red 271
- ballons
- Marty
- inflate
- red 380
- ballons
This is further explained below.
<h3>How many balloons of each color did Marty inflate?</h3>
Generally, the equation for the statement is mathematically given as
w= r+225
w - 225 = r
Therefore
w - 116 = b
Where
r + w + b = 1147
(w - 225 )+w +( w - 116)=1147
3w = 1147 + 341
w = 496
In conclusion, For Red
w - 225 = r
496 - 225 = r
r=271
Marty inflate red 271 ballons
For blue
w - 116 = b
496 - 116 =380
b=380
Marty inflate red 380 ballons
