Answer:
2n-7
Step-by-step explanation:
"7 less than twice a number n"
is the same as
"7 less than (twice a number n)".
I put ( ) around that one part because I want you to focus on that part first.
Twice a number n means 2 times that number n or 2n.
So now we have
"7 less than 2n".
This means 2n-7.
Answer: 5°
Step-by-step explanation:
You can use a right triangle to solve
Hypotenuse would be the flight path
One leg (opposite) is the tree 65 ft
Tan (Θ) = opposite/ adjacent = 65/750
Θ = arctan (65/750)
Θ = 5°
so get the people down to unit rates first
Natalie= 40 in 9 minutes
Steven= 10 in 3 minutes
multiply Stevens to get it even
so by 3
30 in 9 minutes
so Natalie paints faster
