Answer:
x=16 y=38
Step-by-step explanation:
x+y=54.......equation 1
x=y-22........ equation 2
substitute
y-22+y=54
2y-22=54
2y=54+22
2y=76
y=76/2
y=38''
x=y-22
x=38-22
x=16''
How to find the percent of change between numbers
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
If your answer is a negative number, then this is a percentage decrease.
To calculate percentage decrease:
First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.\
% Decrease = Decrease ÷ Original Number × 100
If your answer is a negative number then this is a percentage increase.
If you wish to calculate the percentage increase or decrease of several numbers then we recommend using the first formula. Positive values indicate a percentage increase whereas negative values indicate percentage decrease.
The answer is 24.22%

Answer:
-1/4
Step-by-step explanation:
We can find the slope of a line given two points by using
m = (y2-y1)/(x2-x1)
= (-2- -1)/( -4 - -8)
= (-2+1)/(-4+8)
= -1/4
Her shoe may be about a foot, definitely not 3 feet (a yard.) A yard length shoe does not seem average or the normal size.
Therefore, Bella's shoe is less than one yard.
