First you need to find the slope.
You do this by adding x to both sides to get 3y=x-12
Then, you divide by three on both sides to get y=1/3x -4
to find the new y intercept you insert the point and the slope in the equation
2=1/3(18)+b
You multiply 1/3 and 18 to get 2=6+b
Finally you subtract 6 on both sides to get -4=b.
This means that the equation of the line is the same as the given line
Puppies : Adults = 1 : 4
Total parts = 1 + 4 = 5
5 parts = 100 dogs
1 part = 100 ÷ 5 = 20 dogs
Answer: 20 puppies
Answer:
Correct answer is x = 28°
Step-by-step explanation:
Okay we know Angle A is 2x + 2
Angle B is 90
Angle C is 180 - 148 = 32 ( straight line angle is 180)
Sum of all angles should be 180 in a triangle
which means
A + B + C = 180
2x + 2 + 32 +90 = 180
2x + 124 = 180
2x = 180-124
2x = 56
x = 56/2
x = 28
Answer:
x= 
or 0.5
