Answer:
12.3
Step-by-step explanation:
You will use cosine to solve for y because you are given the hypontenuse and need to find the adjacent side.
cos 35 degrees = adjacent/hypontenuse
cos 35 = y/ 15
15( cos35 ) = y
y=12.287
=12.3
The tenths place, starting from the right, it gets higher going to the left. so the tenths place is only ten times greater than it.
4x=251
251-84=167
4x=167
X=41.75
One tire will cost $41.75
9(-6x-2)-7(-10x-2)
Simplify, by distributing the 9 and the -7
-54x-18+70x+14
Combine like terms
16x-4 is the simplified expression
Hope this helped!
