Answer:
see explanation
Step-by-step explanation:
- 2.3 + (- 5.7)
reminder that + (- ) = -
To obtain - 3.4 it is likely that she added 2.3 to - 5.7
The solution is
- 2.3 - 5.7 = - 8
Answer:
I can't submit a photo but here:
x = 4, y = 16
(4,16)
You can choose whichever format
Step-by-step explanation:
We have x given to us already. Since we know the value of x, we can input the value into the other equation to solve for y
Solve:
Substitute 4 for x:
- y = 2x + 8
- y = 2(4) + 8
- y = 8 + 8
- y = 16
Our solution is x = 4 and y = 16, or (4,16)

n=9
Answer n=9
Answer: a<13
Step-by-step explanation:
a*(a+1)<a^2+13
a^2+a<a^2+13
subtract a^2 from both sides:
a<13
If AB=AC then It is an isocoles triangle. Because of this, Angle ABC=ACB, meaning they are both 60°. This means that Angle BAC is also 60°. Becasue of circle theorms, the angle BOC=2BAC so angle BOC=120°
