Answer:
21/4
Step-by-step explanation:
3/4 x 7
you need to multiply 7 by the 3 which gives you 21
so 21/4
Answer:
Greater than.
Step-by-step explanation:
Let the original value be x.
A 50% increase in x is given by
x + 50%x
=> x + 0.5x
=> 1.5x
Followed by a 33
% decrease in the value gives:
1.5x - 33
%(1.5x)
=> 1.5x - 0.33(1.5x)
=> 1.5x - 0.495x
=> 1.005x
Since 1.005x is greater than the original value, x, then:
A 50% increase followed by a 33
% decrease gives a value that is greater than the original.
Answer: The b-value is the middle number, the number next to the X
X+y=155. Y= -x+155
1.50x +4(-x+155)= 520
1.50x-4x+620=520
-2.5x =-100
X= 40. Y=110
