(6 • 3 - 2x +3) - (-3 • 3 + 5 • 2 + 4x - 7)
first lorne added all binomials
(21 - 2x) - (-6 + 4x)
then took away the parentheses
21 - 2x + 6 + 4x
added them again o_o
27 + 2x
and ended up you her answer, shown above
There are 3 feet in 1 yard. 300 feet is equal to 100 yards.
2 pieces of rope at 16 yards = 32 yards
1 piece of rope at 12.5 yards = 12.5 yards
1 piece of rope at 123.25 feet, divided by 3 feet per yard = 41.1 yards (approx.)
100 - 32 - 12.5 - 41.1 = 14.4 yards
Now multiply by this number of yards by 3 to convert it to feet.
14.4 x 3 = 43.2 feet
The school club needs 43.2 feet of additional rope.
Well since she exercises 5 times a week, and each morning she runs 3 miles, you would do 3*5=15, so you subtract 15 from 30, which leaves 15. She bikes 3 miles each evening
Answer:
35 tickets at $35, 72 tickets at $25
Step-by-step explanation:
x+y=107 -> 5x+5y=535
45x+25y=3375
simplify, divide by 5 to get
9x+5y=675
Substract
9x+5y=675
- 5x+5y=535
4x=140 -> x=35
y=107-35 = 72
Answer:
1)A parabola is defined as a set of points in a plane which are equidistant from a straight line or directrix and focus.
The hyperbola can be defined as the difference of distances between a set of points, which are present in a plane to two fixed points is a positive constant.
2)A parabola has single focus and directrix
A hyperbola has two foci and two directrices
3)Eccentricity, e = 1(parabola)
Eccentricity, e>1(hyperbola)
4)The two arms present in a parabola should be parallel to each other
The arms present in hyperbola are not parallel to each other
5)It has no asymptotes(parabola)
It has two asymptotes(hyperbola)
