Answer:
300 meters
Step-by-step explanation:
250+150+50+x=750
450+x=750
x=750-450=300
Answer:
D. She only needs to know the measures of two angles, but one of the angles must be one of the remote interior angles.
Step-by-step explanation:
Because we don't know what kind of triangle we're looking at, and none of the lines are parallel or perpendicular, the other responses wouldn't make sense.
As a result, we'll need two perspectives.
C would not work since we would know that the two angles are supplementary if we knew A or B.
If we start with A, we'll end up with B, which is 180-A, and vice versa.
Both A and B are unnecessary.
Answer:
450 students
Step-by-step explanation:
Let s = number of students
1/2 are Americans 1/2s are Americans
s -1/2s = number of students left
1/2 s = number of students left
1/3 of the students left are Europeans
1/3 (1/2s) = 1/6s are Europeans
The rest are Australians = 150
Students = Americans + Europeans + Australians
s = 1/2s + 1/6s + 150
Combine like terms
s = 1/2*3/3 *s + 1/6s +150
s = 3/6s + 1/6s +150
s = 4/6s + 150
Subtract 4/6s from each side
s -4/6s = 150
6/6s - 4/6s = 150
2/6s = 150
1/3s = 150
Multiply each side by 3
3* 1/3s = 150*3
s = 450
There are 450 students
In the graph you can see the point are crossing Y -1 and x= 2,
x-y=xy
2-1=1
Y=1
