C = 180 - 140 = 40
x + 2 + 2x + 40 = 180
3x + 42 = 180
3x = 138
x = 46
B = 2x
B = 92
Answer:
The answer is A
Step-by-step explanation:
When two parallel lines are crossed by another line the angle of 1 will be equal to 4, 5, and 8. The angle 2 will be equal to 3, 6, and 7. Since a straight line has a degree of 180, the subtracted degree of 180-140=40 which would mean 2=40 which 2=6 so 6=40.
Answer:
30 miles
Step-by-step explanation:
300/10=30
30 miles is the answer
Y = 5x - 1...so we sub 5x - 1 in for y in the other equation
-15x - 3y = 3
-15x - 3(5x - 1) = 3
-15x - 15x + 3 = 3
-30x = 3 - 3
-30x = 0
x = 0
y = 5x - 1
y = 5(0) - 1
y = -1
it has one solution (0,-1) <=
Answer:
I believe that her theory is correct
Step-by-step explanation:
this is because the ratio of cups of sugar to cups of flour is 1:3 and if we times both sides by 3 we get 3:9 which is the answer she presents
