35 students would not know any of the three languages, because if 30 know French, 19 knew German, and 16 knew Russian, that must mean that 65 students know at least one of the three languages. So you subtract 65 from 100 and end up with 35
Let x and y be the angles
X= 3•y-8
X+ y = 180
Substitute first relationship in second
3y-8+y=180
4y=180+8
Y =188/4= 47 degrees
X= 180-47=133 degrees
The measure of the large angle is
133 degrees
Answer:
x f(x)
0 0
1 3
2 6
3 9
4 12
5 15
Step-by-step explanation:
since they gave the point (0,0) and slope 3
y=mx+b
0=3(0)+b
b=0
y=3x and then substitute
Question 1:
Perimeter = 18ft
area = 15ft²
Question 2:
Perimeter = 11m
Area = 7.5m²
* eq 1 by 4 and eq 2 by 3 and add
24x-12y=60
21x+12y=30
45x=90
x=2
y=-1
