Answer:
Line 2
Step-by-step explanation:
(x = 2, y = 4)
When we input it into Line 1:
2 + 6 = -2; not true
When we input it into Line 2:
3*2 - 4 = 2; true
Answer:
x = 10

Hoped this helped.
Answer:
The circumference is 56.52 m
Step-by-step explanation:
Eugene likely made the mistake of doubling the diameter thinking that it was the radius which gave the answer double the actual one. The equation for finding a circumference is C=
D where d is equal to the diameter and c is the circumference. All you do is multiply 18 and 3.14 to get your answer.
Answer:
y=5
Step-by-step explanation:
esa es la respuesta
Answer:
x=70
y= 40
Step-by-step explanation:
the triangle containing x is an isosceles triangle so two of the sides are 55.
55+55+x=180.
110+x=180
110-110+x=180-110
x=70
Triangle BAC is equilateral so 180/3=60. Now
x+60+c=180
70+60+c=180
130+c=180
130-130+c=180-130
c=50
That gives us one corner of triangle CBD. We know a second angle is 90 so
50+90+y=180
140+y=180
140-140+y=180-140
y=40
I think that is correct but you are free to check it yourself
