Its simple, the expression is 7+x and it does not have an equal sign since it is not an equation
Answer:
22 miles per hour
Step-by-step explanation:
we know that
The speed is the ratio of distance by the time
Let
d -----> distance in feet
t ----> time in seconds
s ----> the speed in ft/sec
we have
substitute
Remember that
Convert ft/sec to mi/h
To calculate it, first order your data points from least to greatest, then determine your first and third quartile positions by using the formulas (N+1)/4 and 3*(N+1)/4 respectively, where N is the number of points in the data set.
after you do that then say IQ=Q3-Q1
<span>x= 5 + y
28x – 9y = -12
substitute </span>x= 5 + y into 28x – 9y = -12
28x – 9y= -12
28(5 + y) – 9y = -12
140 + 28y - 9y = -12
19y = -152
y = -8
<span>x = 5 + y
</span>x = 5 - 8
x = -3
solution (-3, -8)
