Answer:
Equations are composed for many expressions.
Expressions can indicate variables, constants, etc.
Best regards
A $20 decrease followed by a $20 increase - original value
A 75% decrease followed by a 50% increase - less than the original value
A 50% increase followed by a 33 1/3% decrease - greater than the original value
A 60% increase followed by a 40% decrease - greater than the original value
A 100% increase followed by a 33 1/3% decrease - greater than the original
Answer: Two planes meet in exactly one point
Two lines meet at exactly two points
Step-by-step explanation:
From the given statements there are two statements which are never true :-
1) Two planes meet in exactly one point .
Since when two line meets , they either meet at one point or infinite points (coincidence) , thus its impossible that they will meet at exactly two points.
2) Two lines meet at exactly two points
Since when two planes meet , the intersection of two plane always make a line not a point. Thus its impossible.
Answer:
5x3 + 3x2
Step-by-step explanation:
Let's say stress ball cost x and t shirt cost y
8x+5y=111.75
12x+4y=102.00→3x+y=25.5→y=25.5-3x
8x+5(25.5-3x)= 111.75
8x+127.5-15x=111.75
-7x=-15.75
x=2.25
12x+4y=102
12(2.25)+4y=102
27+4y=102
4y=75
y=18.75
d is the correct answer
