Answer:
Given a is 5
Step-by-step explanation:
I. Given a is 5
= a + 1
= 5 + 1
= 6
6 is divisible by 3 => true
II. Find 4 + 7a value
= 4 + 7(5)
= 4 + 35
= 39
39 is divisible by 3 => true
III. Prove by
6 ÷ 3 = 3
39 ÷ 3 = 13
Hope that help :)
Answer:
4/D a reflection fallowed by a rotation.
sorry if I am wrong
The triangle BAC has two known measurements 30 and 90 so add those together and subtract by 180
30 + 90 = 120
180 - 120 = 60°
Ok so first plug in y for in the equation 2x-2y=12
Therefore 2x - 2(x -6)=12
Then distribute the two to the x and the -6
2x-2x+12=12
The 2x's cancel leaving you with
12=12
From there you could subtract the 12 from both sides to get 0=0, I assume
