Answer:
A
Step-by-step explanation:
For test A, the unit rate is 30 words per minute divided by 4 minutes, or 7.5 words per minute.
Unit rate = 78 words/15 minutes = 5.2 words per minute for test B.
The unit rate for test C is 99 words/22 minutes, or 4.5 words per minute.
The awnser IS no it is not a true statement
Vertical angles are congruent
2x+50=7x
50=5x
x=10
2(10)+50
20+50
Angle AEB = 70
Answer:
The equation of line for given points is y = - 40 x - 42
Step-by-step explanation:
Given two points as :
( -1 , - 2 ) and ( 3 , - 162 )
Now, Equation of line in points form
y -
= m × ( x -
)
Where m is the slope of line
And, m = 
or, m = 
or, m = 
∴ m = - 40
So, Slope of line for given points is - 40
Now equation of line can be written as
y - ( - 2 ) = ( - 40 ) × ( x - ( - 1 ) )
or, y + 2 = ( - 40 ) × ( x + 1 )
or, y + 2 = - 40 x - 40
or, y = - 40 x - 40 - 2
∴ y = - 40 x - 42
Hence the equation of line for given points is y = - 40 x - 42 Answer
Answer:
if you use a calculator its easy
16.72 - 1.24 = 15.48
15.48 divided by 12 is 1.29
for sales tax 1.24 divided by 12 is .10
so for each one She spent $1.39
