In the general case, it is (x, y+3), where y = f(x).
Let the number of islands visited be x and that peninsulas be y
thus,
x+y=19
⇒y=19-x.........i
if he skydives twice in islands and thrice in peninsulas, then the total number of skydives will be:
2x+3y=45.....ii
substituting i in ii we get:
2x+3(19-x)=45
2x+57-3x=45
putting like terms together we get:
2x-3x=45-57
-x=-12
therefore
x=12
and
y=19-x=19-12=7
hence the number of islands visited was 12 and that of peninsulas was 7
Answer:
110/289 feet
Step-by-step explanation:
Step one:
given data
Area of the floor= 55/14 square feet.
The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet
Step two:
The expression for the area of the room is
Area= L*W
55/14= 17/2*W
55/14=17W/2
cross multiply
17W*14=55*2
289W=110
divide both sides by 289
W= 110/289 feet
Answer:
6x^2 -4x +8
Step-by-step explanation:
(6x^2 + 5) - (4x - 3)
Distribute the negative sign
(6x^2 + 5) - 4x + 3
Combine like terms
6x^2 -4x +5+3
6x^2 -4x +8
