Solution steps:
1. Add the two given fractions.
2. Subtract the sum from 10 to find your answer.
Answer:
Step-by-step explanation:
an equation is : y = 10x+b
calculate b : this line passes by : (7;1) when x =7 y = 1
so : 10(7)+ b=1
b= -69
so : y = 10x-69
So, we know that the internal angles of a triangle add up to 180 degrees, yes?
60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.
Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!

Answer:
area = 40.8 cm²
Step-by-step explanation:
The figure consists of a rectangle and a triangle.
area of rectangle = 12 × 2.4 = 28.8 cm²
area of triangle = 
bh ( b is the base and h the height )
Here b = 2.4 and h = 18 - 12 = 6 , then
area = × 4 × 6 = 2 × 6 = 12 cm²
area of figure = 28.8 + 12 = 40.8 cm²
Answer:
(7, 5)
Step-by-step explanation:
When reflecting over the x-axis, the only position that moves is the y-coordinate as it is going above the axis it was previously below. Since point F's original position was (7, -5) it is 5 spaces away from the x-axis. We move 5 places up to be even with the x-axis, then move up another 5 places to reflect the point to get F'.
Hope this Helps!
