The answer is <span>2(–4y + 13) – 3y = –29
Step 1: Express </span><span>x from the second equation
Step 2: Substitute x into the first equation:
The system of equations is:
</span><span>2x – 3y = –29
x + 4y = 13
Step 1:
</span>The second equation is: x + 4y = 13
Rearrange it to get x: x = - 4y + 13
Step 2:
The first equation is: 2x – 3y = –29
The second equation is: x = - 4y + 13
Substitute x from the second equation into the first one:
2(-4y + 13) - 3y = -29
Therefore, the second choice is correct.
Hi.
Your answer is going to be
C.) 33
Hope this helps! :)
You would just have to isolate for x
so it would simply become
-1.56/-7.8
= 0.2
Answer: 27.47
Step-by-step explanation:
(sin(70) * 10) / sin(20)) = 27.47
