Answer:
65
Step-by-step explanation:
So let's first set up our equation here:
35 + 42 = 12 + x
Now, let's add like terms
77 = 12 + x
Now, let's subtract both sides by 12
65 = x

Answer:
-3
Step-by-step explanation:
When a line is perpendicular, the slope becomes the opposite to the original. If the slope is 1/3, the perpendicular line's slope would be -3.
Answer: A
Step-by-step explanation:
The line and dots are closed circle, so B and D would not be the answer.
The line have passed through the point (-6,4) and (0,2); we uses to find the slope.
slope = m = (y2 - y1)/(x2 - x1) = (2 - 4)/(0 - (-6)) = -2 / 6 = -1/3
we plug in slope to the linear equation in form of y = mx + b, where m is the slope, and b is the y- intercept.
y = -1/3x + 2
So the answer is A.
3 1/5 x 7 1/4
= (15/5 + 1/5) x (28/4 + 1/4)
= 16/5 x 29/4
= (29x16) / (5x4)
= 464/20
= 116/5
= 20 16/5
