Answer:
3 oil changes
Step-by-step explanation:
1. Find an equation that represents this word problem: 3000x + 5000 = y
Where y = the # of miles total. y = 250 miles/week * 52 weeks/year = 13000 miles.
2. Solve for x: 3000x + 5000 = 13000 3000x=8000
3. x = 8/3 integer round down x = 2 oil changes, but plus the one after 5000 miles is a total of 3 oil changes that year
Answer:
36.87°
Step-by-step explanation:
Since ABC is a right-angle triangle, we can use trigonometric ratios to solve for unknown angles and sides.
For Angle at A, we have lengths of opposite and adjacent sides so we can use tangent at A.
tan(A) = opposite/adjacent
tan(A) = CB/AB
tan(A) = 6/8
A = (tan^-1)(0.75)
A = 36.86989765°
Answer:
Step-by-step explanation:
put x = 3 and y = 6 in (x+3,y-2) so it becomes (6,4)
All paragraphes should have a leading and supporting clause. just like this hre, "I love tocas."
