-1.5(4-n) + 2.8 - 1.5(4-n) + 2.8
Two ways of solving this, you can just expand and solve, or combine like terms then solve. I will combine like terms.
<span>-1.5(4-n) + 2.8 - 1.5(4-n) + 2.8
</span>(2*-1.5)(4-n) + (2*2.8)
-3(4-n) + 5.6
-3*4 + 3n + 5.6
-12 + 3n + 5.6
3n - 6.4
Answer:
32.98 ft
Step-by-step explanation:
What you have right there is a triangle.
The base of the triangle is given (14 ft)
The angle from the ladder makes while leaning on the house is 67 degrees.
This is a simple trigonometry problem
You want to find the length of the ladder and you don't have the hypotenuse
So you can use the function tan to find it.
tan(Ф) = opposite/adjacent
You are looking for the opposite side length
So you do tan(Ф) * adjacent = opposite
tan(67) * 14 = 32.98 ft
Answer:
12/17
Step-by-step explanation:
total number of marbles that are purple (11) plus the total number of marbles that are not small (15) minus the number of marbles that are both purple and not small (2)
11 + 15 - 2 = 24
over the total number of marbles (34)
24/34 simplifies to 12/17
Multiples of 3 are like 3,6,9,12,15 so 15s a multiple
(5,-8) after a 180 degree counterclockwise rotation about the origin is (-5,8)
