Answer:
add otherwise I don't know sorry im on that question
Step-by-step explanation:
45 miles per hour is 3/4 mile per minute. Divide 4.8 by 0.75.
Answer is A.
step 1 , 16 was not multiplied by 9
should be
54x - 9y = 144
we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

Step 1
<u>Find the slope of the given line</u>
we have

Solve for y
Divide by
both sides


the slope of the given line is 
Step 2
<u>Find the slope of a line that is perpendicular to the given line</u>
we have



substitute the value of m1

therefore
<u>the answer is</u>
the slope is 
X=number of students at Marita's high school last year
98%=.98
.98x=1170
x=1170/.98
x=1194
