Fraction form 3/2 or 1.5 in decimal form :)
Answer:
45
Step-by-step explanation:
If two lines are parallel and cut by a transversal, corresponding angles are congruent. Angle GEB and angle EFD are corresponding so they are congruent so you can set them equal to each other and solve.
2x - 30 = x + 15 (add 30 to both sides, subtract x from both sides)
X = 45
Answer:
h
Step-by-step explanation:
Answer: Because the y terms cancel
Step-by-step explanation:
Hi, this approach is called the addition method.
By adding both equations we can cancel one term that contains one variable, and calculate the remaining variable.
For example, in this case:
8x + 3y = 27
+
4x-3y = 9
_______
12x = 36
Now, we can solve for x:
x = 36/12
x = 3
Now, simple replace the value of x in any equation to obtain the value of y:
4x-3y = 9
4(3)-3y =9
12-3y =9
12-9 = 3y
3 =3y
3/3 =y
y=1
