In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.
Answer:
solution
100 tins of corned beef =36 g
1 tin of corned beef = 36÷100=0.36
so, 1 tin of corned beef is 0.36 g.
Answer:
8
Step-by-step explanation:
Using the Heron's formula we can find that the total area of the triangle is 84 inches.
Then, to find the height of the triangle, you have to multiply the area by 2 since the formula for the area of a triangle is (h*b)/2
Now, when we multiply 84 and 2 we get 168, so you have to divide 168 by 21 to find 8.
Answer:
<u><em>Observe the attached image</em></u>
Step-by-step explanation:
We have the graph of a line that passes through the points (0,5) and (2, 1).
The equation of the line that passes through these points is found in the following way:
Where
m = slope
So
We must apply to this function the transformation.
We know that a transformation of the form
shifts the graph of the function f(x) h units to the right if , or shifts the function f(x) h units towards the left if .
In this case then the transformation displaces the graph 4 units to the right.
Therefore if f(x) passes through the points (0,5) and (2,1) then passes through the points (4, 5) (6, 1)
And its equation is:

Answer:
B) y=2x+3
Step-by-step explanation:
2x+3 2 is the slope it goes up two over one 2/1 or 2 and +3 is where the line intersects the y axis ( -3 would mean that the line intersected at -3 )
